The new Benjamin Maximus was introduced this year as a less expensive, entry level, Precharged Pneumatic air rifle capable of taking small game. It arrived at my door on the morning of June 10, 2016; and the barrel was quickly cleaned in preparation for shooting (barrel was relatively clean.) It had about 1,000 pounds per square inch of pressure when it arrived. So airing it to 2,000 PSI took only about 50 strokes of the Benjamin hand pump. Next the fiber optics sights were removed before installing the scope. The Benjamin sling that I received with the rifle (but purchased separately) was fitted to the rifle.
Everything was ready for the sighting process to begin. I shot five Crosman Premier Hollow Point pellets to locate the point of impact. Then I switched to the Crosman Premier Box Domes 14.3 gr that I plan to use for hunting squirrels. With the first adjustment to the scope completed, a couple more pellets were sent to the target. One more adjustment to the scope centered to point of impact. Five shots (one flyer) placed four in a tight circle the size of a nickel. Total number of shots = about a dozen.
First impressions of the rifle:
1- Accurate
[size=78%]2- Light and durable looking - should be ideal for hunting[/size]
3- Hollow plastic stock caused the rifle to feel a bit muzzle heavy
4- Loading is easy - even with the scope mounted
5- The barrel band is farther forward than the one on the Discovery rifle - that is a plus for me
6- Sling studs already installed - another plus [even though they needed to be drilled larger to fit the Benjamin sling swivel >:( [/size][size=78%]][/size]
7- At the current price, the rifle should be a hot seller.
I would give the new Maximus FOUR stars out of a possible five!

Good solid review on the Maximus. I was going to do a review on my Maximus .22 but no need as your description is spot on, even down to the brown box CPL's :)
I agree, at the offered price it should sell well.

I do not like youz peoples. I am selling my extra guns so I can buy a compressor. I do not need to see this stuff, because it is making me lust. :( I would like to have one in both .22 & .177. LOL

Did a lot of shooting in the backyard range today after installing a TKO. Did pellet grouping tests with all the .22 cal pellets on my shelf and found out it really likes Predators, CPL's, JSB Exact Express, JSB Exacts, Beeman FTS, Kodiaks and GAMO Hunters. Gave great groups on every one of those pellets. I did the final sight in with the brown box CPL's.
On a 2000 psi fill my rifle is giving me 20 good hunting shots with shots 21-25 starting to show a drop in POI.
My only complaint is that every once in a while the bolt will "pop up" when I fire. Doesn't happen all the time, just once in a while but it annoys me so I'll address that issue.
Spent about 2 hours in the range and had a blast :) First chance I get I'm gonna head over to a local vegetable farm I hunt on that's loaded with woodchucks and see if I can get her her first harvest :)
Great little rifle, really happy I bought it. :)

Hey, Jesse; listen to this: Maximus! Maximus! Maximus! Maximus!
Doesn't that sort of get your juices stirring!
Jeff, one of the first thing I installed on the new Maximus was the rubber band for the bolt. Not beautiful, but it works for me.
-
You read my mind Mike :)
My .22 disco doesn't have this problem but my .177 disco does and the rubber band worked like a charm so gonna "install" one on the Maximus as well :)
Like you said, it's not beautiful but it works great.
Jeff
-
For those of you that have a Discovery or Maximus with the bolt problem (the bolt doesn't close firmly), this is the rubber band fix we were talking about. Too easy not to give it a try - you might like it!
Just loop it over the end of the bolt after loading.

Alrighty now. Just got my Maximus kit today from Crosman. $300.21 shipped including a Fathers Day special 760 pumpmaster. Initial impressions were not good at all. Although packed well the freebee included pellets escaped their tin, rattled all over the box, including one lodged in the muzzle and somehow the lid managed to get back on the empty tin. Some slight lead marking all over the gun too. Not worth sending it back. I will call Crosman or write them a note about it. Gun had 1,000 PSI in the chamber. The bore wasn't as dirty as expected and after cleaning it took 50 pumps with the included hand pump to bring it to 2,000 PSI. Shooting the included pellets I started with 5 shots in the 805-810 range. 4 shots later it was 818 and climbed to a high of 832 with the vast majority were between 825-830 for 17 shots. Seems like the sweet spot was 1800 to about 1400 for these 17 shots. Mind you these were the Crosman Piranha pellets that were loose in the box.
After pumping it back up to 2,000 PSI I mounted a spare BSA Sweet 22 3-9x40 and went to shooting paper using some Walmart 14.3 HP from the tin. The first 10 shots were used to sight it in and the next five made one sub 1/4" group at 30 yards. In the wind. Not a breeze, but some good wind. I shot it down to 1,250 PSI popping clover flowers off the stems and proved the target was the norm for this gun. 21.4 FPE measured 6' from the muzzle and tiny groups with cheap pellets? Heck yeah I'm happy!
Now, what to do about the horrible, terrible, awful trigger.
-
Great reviews... you guys have me tempted to buy one.

Jeremiah, the Maximus is not a twin to the Discovery; rather it is a younger brother. If you would like a fine shooting, light weight, accurate, and inexpensive rifle, the Maximus is for you. GO FOR IT! JMHO.
-
Now, what to do about the horrible, terrible, awful trigger.
there are good write-ups on the three screw Discovery trigger (same as the Maximus one) mod along with using a ball point pen spring to replace the factory trigger return spring. It's super easy to do the simplified version of the two screw mod sans the one under the trigger guard + the spring replacement. It made my trigger a lot better than the form it came from the factory.
Also get the TKO brake. It makes the gun shot sound like mouse fart.
-
I let the Maximus sit for a couple weeks while my Judy and I went to Tennessee. Upon our return, I checked the pressure gauge and saw that it had not changed any.
I went out in the back yard to do some shooting - (it is okay because school is out for summer vacation). I had a paint can that was no longer usable. I shot it about eight times. No misses at about 30 yards.
That brings the shot count to about 20 on a 2K fill and I still have 1,200 PSI. Maybe what the advertisement says is true concerning the shout count - up to 30 shots on a fill. But for hunting, I probably would not go much below 1,200 PSI.
I am liking this rifle more each time I put my hands on it.
-

I did my own version of these mods. The biggest grit producer in the trigger group was the sear spring to sear interface. Unfortunately adjusting the overtravel screw to the point I like it causes the sear to drag on the hammer giving reduced and inconsistent velocities. The trigger is much, much better but still a little heavy. It's a hunter so it I will adapt. The pretravel screw for the trigger didn't do much for me so out it came. I did drill a hole in the bottom of the stock to allow adjustment of the screw that limits sear engagement .
The first tin of 500 is empty. My spinners are beat up, the Starlings have learned anything within 50 yards is my land and a coon going after the Chickens is now Buzzard fodder.
What I have learned:
My HW95 is HEAVY!
I like the exercise I get pumping the gun back up. At nearly 60 and in a management position I don't get enough exercise at work.
The Synco is consistent. No changing POI on this one. The shots between 2,000 and 1,850 are not as accurate as the 1,850 down. Once velocity drops off you can shoot this gun down to about 800 PSI before you hear the Buuuuuurrrrp of the hammer bouncing. Those remaining shots fall off is a nice line. As long as you don't have scope cant.
-
I'm a little disappointed in the Crosman Customer Service Dept. and disgusted in their Quality Control. I've sent my .177 Maximus back with their postage paid label with the, what I thought was an agreement that once they received the shipping notice they would send out a replacement gun. I haven't received a shipping notice after several contacts with them. Just a reply email asking to spell my last name and zip code. This information they already had during the initial contact. ( Sorry just venting, had to return two Amazon orders also but those went super smooth. ) I really wanted to get this set up for my father before I headed back on vacation but looks like I'll end up shipping it sometime later. I've already posted the issue with my barrel lacking rifling and no crown. Seems I should have gone with the .22 version, it still sounds like a low cost winner.
-
Mr. TKO (Mike Tiehen) must have shipped my LDC five minutes after he received my order. I placed my order on Friday (June 24) at about 2 p.m. and received it in the morning mail about 9 a.m. today (June 30).
After shooting twenty pellets through it, my opinion is that it is quieter than the AC Custom Shroud that I have on my Discovery. THANKS MIKE!
The Maximus is using about 800 PSI of air for those 20 shots [as mentioned in an earlier post.) The wind was moving the pellets around a little. <--- If I had been shooting at real squirrels, I may have missed one out of the twenty shots. ;)
-
Looks like a TKO is easier to put on a Maximus vs. a Disco, without getting in the way of the fill connector.
-
Jerry, that is a TRUE statement! Immediately after I got the TKO positioned firmly on the barrel, I charged the Maximus up. NO PROBLEM attaching the fill line. However, there is a little problem with my gun case - now it is too short for the Maximus. Academy, here I come. ;D
-
Great reviews... you guys have me tempted to buy one.
Jay
me to ;D(http://www.ecedc.com/bass.jpg)

I just came across the AirGunWeb (Rick Eutsler, Jr.) review of the .22 Maximus that Rick bought. It is short and to the point; and even has a little hunting segment at the end.
https://www.youtube.com/watch?v=nuxfepy61Yc (https://www.youtube.com/watch?v=nuxfepy61Yc)
-
He must have bought and reviewed a lemon. I get much better accuracy from mine. Just now working on the JSB 15.89 gr and it seems like it's a much better pellet for the gun. No fliers and holds energy better than the Crosmans. Need to do a shot/chrony run next.
-
Now that I have had a little trigger time (four hunts), I would like to say a couple things about the Maximus .22 I am using.
a] This rifle is lighter in weight than the Discovery .22 I used last season. Therefore, it is easier on the back when carried on the sling while bicycling to the woods. Also, it doesn't tire my right arm when not slung during hunting time.
b] I did re-sight my rifle after the third hunt (I missed two squirrels.) It was hitting about 1.5 inches to the right and one inch low. The adjustment was quick and painless though; and I went right back to taking squirrels with head shots.
c] The Maximus seems to be easier on air than my Discovery while hitting with near the same energy.
Let us know if you agree or disagree.
-
Mike, I agree with you on being light and more air efficient. I have the maximus .177 and this thing is averaging about 970fps out of the box. Polymags are fantastic in this gun, they hit with authority. I have taken squirrels out to 40yds so far with it. The Disco I have is still my go to gun for the bigger stuff but the Maximus will probably be my squirrel gun this season.
-
the Synco shoots well the disco shoots well.they hit really good to 40 yards.synthetic stock and sling mounts are a plus.add the brass trigger mod and trigger is much better.i shooting the jsb 15.9 pellets so far and it places them where I aim...I sighted the Synco in on a knot on a board haven't shot it at a target yet...I like it a lot and thinking of retiring my 22Mrod in favor of the 22 Synco...
-
I had a problem with shifting POI on the horizontal plane and attributed it to bumping the muzzle. Brass shim stock .005" thick placed around the circumference of both the barrel and air tube under the barrel clamp solved the problem. Out past 40 yards I really depend on my scope level to assure good hits. The JSB 15.89 is my match pellet and is giving very similar trajectory that the Crosman 14.3 from the tins gives.
-
I chose the CP Box Domes for hunting because I thought the Maximus would be pushing a little less energy than the Discovery. I figured the Box Domes would penetrate better than the JSBs because they are harder. So far, there is no problem getting good penetration from the Maximus - Box Domes combination. And the Maximus doesn't seem to be any more pellet picky than the Discovery. Both shoot several pellet well with only slight scope adjustments necessary when switching from one to another.
-
Ill be putting in an order for mine along with a marauder trigger and bnm breech and shroud
-
I'm not sure if Chairgun number are accurate but for me I show 12 lbs/ft at 50 yards using the Crosman and 14.7 with the JSB. If you can tolerate the occasional flier, the cheap Walmart tins are cheap shooting.
-

I will probably start using the JSBs when I run through all the CP Box Domes I have left. For hunting, I need the best accuracy and consistency that the rifle is capable of shooting. And the cost is a small consideration because I will use only about 100 pellets during the Fall/Winter season. With the JSBs, 100 pellets is like $3.00.
Thanks for the replies, guys.

To be in compliance with the Forum Rules, I have modified the following material taken from another thread.
This is a comparison of the Benjamin Maximus and the Benjamin Discovery.
My Maximus is lighter than my Discovery for a couple of reasons:
Hollow plastic (Maximus) is lighter than solid wood (Discovery).
My Maximus has a lighter scope than my Discovery = less overall weight there too.
Because of the hollow plastic butt portion of the stock, the Maximus has more weight forward.
Conclusion: My Maximus is more comfortable to carry bicycle riding and for longer hunts. And because I shoot off sticks about 99% of the time, the weight forward is not an issue. I like the Maximus very much; but I don't think it can outshoot the Discovery -- might be an even match there! YMMV
-
I just picked up a maximus, in .22, yesterday. i'll eventually write a review, but for now, just a couple of observations.
from a 2000 psi fill, I got 30 shots starting at 791, and ending at 793. if I drop the fill pressure to 1850, I get 20 shots starting at 819 and ending at 805. the majority of the shots are 823 - 827 fps. I can't wait for the huma reg to arrive. I figure a setting of 100 bar should be perfect.
it would seem that crosman has been doing their homework. the hammer spring is heavier than the disco, as well as shorter. as far as I can tell, there is little to no preload on the spring, which would account for the flatter shot string.
more later, when I have the time.
-
Now, that I have about 150 pellets down the barrel of my Maximus .22, I wanted to say a few things about this rifle’s performance:
The Maximus is starting to "wear in”; the bolt is getting smoother and easier to cock.
I was having some issues with consistency until the Christmas scope was mounted on the rifle.
The shot count has remained the same. I am still shooting the Crosman Premier Box Domes.
I did some target shooting with a friend over the Christmas Holidays. I used several different pellets. Each one shot to a different point of impact. But it seems all were grouping nicely with only a couple flyers - maybe the flyers were my fault too.
The new scope - Oh, it is a Bushnell Bone Collector. Like I told my son today, I LOVE THIS SCOPE!
-
I too have a new .22 Maximus in the house.
And I LOVE it! I am a bit of a gun and scope snob. I haven't' touched a pellet gun in quite some time, spending my shooting hours shooting a .257 TalonDor by Dyotat100 and R&L Airguns, with a lot of mod's performed by your's truly. It is a true tack driver at 100 yards and well beyond, using my cast bullets.
The last good shooter I had here in a actual pellet shooter was a Daystate MTC Air Wolf, and it was very accurate.
Now here comes the rub. I am shooting a heavier pellet than any have so far posted. The 18 gr. JSB, and in factory trim, the Maximus is shooting the JSB 18 at 820 to a high of 836. This is something I did not expect. As it is shooting the 18 grainer faster than what I have seen posted for lighter pellets.
but as we all know, a fast miss, doesn't' count for much. Or as a friend of mine likes to say, you can't miss fast enough to win in a gunfight. Not even a showdown with Mister Grey Squirrel . And nothing could be closer to the truth.
Wanted to test a few different pellets, and tried the new crossman piranha suckusucks at wallyworld, as I was there a few days before the Maximus arrived. They are a wicked looking new hollow point. I won't say much about it other than the results were terrible. (It was all that Wally had in stock at my local store). Every shot was a confirmed flier.
Next up were the RWS SuperDomes. Not as bad, but BAD!!! As over 1 inch at 30 yards bad!
I had a tin of 18 gr JSBs here that were left over from the aforementioned Daystate A.W. Too heavy, by all accounts, but I gave them a try, as they were all I had left.
What the-They were, well, I was scared they were missing the target, so I put my Zeiss Scope on the gun and could actually see each and every pellet slip thru the same hole. 8) (Yes, I said Zeiss, worth a half dozen or more of these little AG's). Every single pellet. I went so far as to shoot three fills at the target at the same poa. That was 60 pellets. Not one single flier. Not one! And every single pellet slipping thru a hole not much wider than 3/8"!
This, light, cheap, whippet barreled entry pellet rifle was shooting as well as the old Daystate at this range. Sure it was crude by comparison. And The trigger was heavy, but no creep, nor was it gritty, as I have heard often. Just smooth and heavy!
I moved out to 50 yards, and the group grew to a good 3/4 inch after ten shots. Another group of 5 was dead on at 1/2".
OK, on to 70 yards. Ten shots were one hole, but a rather large one. About one inch left to right, and 1 1/4" top to bottom. Woha!!! Is this even possible? The Air Wolf, with its' precision barrel, and electronic trigger set at 7 oz. just barely out shot this gun. And I only paid 179 with free shipping for it.
I'm stoked, yes, but in shock more than anything. But at the same time, my wife had a hard time wiping the smile off my face. And once I showed her the target, she was as shocked as I am.
Rec'd a TKO this evening. Will test it once this high wind cold front passes by the weekend. I'm a Texan. Anything much below 72F really ticks me off! ;) I sure hope the TKO doesn't diminish the fine accuracy I am getting with this little light weight Air Rifle. ;)
Guy's, trying the 18 grainers from JSB might give you surprising results. They are sure going to help in the Texas wind. I didn't mention that I had a 9-10 straight in North wind while testing. The results were hard enough to believe as it was!

Great description and shooting Michael. I'll have to try those 18's!
-
only reason I shoot the 14.3 crosmans, is I can pick them up locally. I won't keep a gun that I have to order ammo for, on line. If you look at my list of acquisitions, the only gun that doesn't shoot the crosman tin pellets is the stock beeman P17. it eats the really cheap daisy wadcutters. and, of course, the Sheridan, but, even that likes the Benjamin pellets, which, I can also buy locally.
all of the guns are one small ragged hole shooters, with the crosman tins. whether they're .177, or .22 cal. like I said, I wouldn't have them if they didn't.
-
wish I could find the .22 crossman P's here. They carry a "C" load of .177's, though.
I wonder if wally world knows that over 78% of pellets sold in the U.S. are .22?
Times have changed. Catch Up Wally World! 8)
Tater, did you every get rid of that fine looking cat? Had a bunch of very similar looking ones here last spring. Emphasis on "Had". LOL

Just a quick update on the Maximus and pellets:
This week, I received a shipment of JSB pellets in 15.89 gr and 18.13 gr. I ran about 20 of the 15.89 gr through the Maximus .22. As consistently accurate those are in my Discovery .22, the Maximus was spreading them out - side to side and from the center down. Not what I was hoping for.
I will be giving the 18.13 gr a try later this week. Watch for the report later.
"Jason Patin" came by for a short visit yesterday and had high praise for the 18.13 gr pellets. He was surprised as the high amount of energy that these pellets carried at 70 yards.
-
Thanks for the update Mike.
-
It was late and a little windy but I wanted to take a few shots with those new 18.13 gr JSBs. From the limited amount of information provided this afternoon, I think the group was pleasingly tight. The pellets were consistent through the top pressure range. But here is a little something that concerns me: It looks like those pellets are using more air per shot.Conclusion so far: More testing is needed.
EDIT: Jerry, we were typing at the same time. Thanks for your reply and here is another small update.
-
I got some 18.13 JSBs recently as well and they are grouping better than any other pellet I've tested so far. Otherwise the closest is the Vortex Supreme 14.66 which I believe are also some rebranded JSBs.
-
Vortex Supreme 14.66 gr - I will have to keep those in mind once I shoot all these JSBs. And maybe by then, they will have come down in price a little.
Thanks for the reply.

Guys thanks so much for the review, info and findings.
I want to give a quick explanation why I am responding to this.
My son has a birthday coming up in a couple weeks. He is turning 15. Its a good thing but a sad thing also. My little boy is growing up. I guess its just another stage in our life.
Well, I was able to take my boy out hunting for some rabbits and BTs the other day. I was carrying my Mrod .22 and he was carrying my oldest sons Ed tuned .177 tac driving Gamo. (Thank you Ed). Unfortunately, the birds weren't even moving. Of course this cause my son to get figgity and he started messing with the scope cap. Next thing I hear is him coming through the woods saying he has messed up the scope because he heard it clicking while he was messing. (Long fingered youngen....)
This allowed us to change from hunting to shooting. He had a great time. We finally got his Gamo zeroed back it to almost center shoot a bottle cap at 25yard. I let him shoot the Mrod and boy did he fall in love. Accuracy AND he didn't have to break the barrel. I set the bottle up at 25 yards and he dead centered the cap and almost split it top off. I couldn't have been more proud of him. He said its so easy to shoot, and so quiet. Long story short, he wanted one.
No here is why I am so proud of him. Now, I'm NOT complaining or whining. My son has always been a little different. He has always had some little health issues. His development has always been a little behind but he always gets there. He developed an issue with toe walking a few years back and now its his norm. He can't get flat footed. We have tried stretches and other thing and he did well for a while but a growth spurt hit and back up he went. So disheartening.... I guess we are going to have to look at surgery before its over. Poor child. He has had eye surgery twice. He knows he doesn't want them cutting on his feet but what else can we do?....
This condition has caused him to be less than active as most young guys his age. Not as coordinated and so forth. I try to keep close to him and be his friend. We really love each other.
As we were out hunting, he grew tired and had to sit down in the field as I finished the round. I came back and picked him up in the little truck and off we went to the above mentioned BT hunt and shooting.
Now when he shot the Mrod, he loved it and I want to get him one BUT, its way to heavy for him. I did a lot of research and your post here helped me in my delima. I now have a .22 Maximus with a 6.5 LDC from TKO on the way. Ordered some JSB 18.1s and scope rings for a scope I have here. Im looking forward to getting it all set up for him.
I can't wait to see the look on his face when he gets it. Its light, easy to shoot and he won't have to struggle with cocking a break barrel. I want him to FULLY enjoy shooting and hunting with me.
Thank you again for your posts.
Shadowshot.
Oh yeah, couple of pics of the shots. Close to centered cap top was at 25 with the gamo springer in .177.
The split top was his first shot at 25yards with the .22 Mrod.
I hope he likes the Maximus.
Dang, sorry for the long post. Guess I needed to vent a little
-
Paul, that was a very nice post you made here.
I hope that young guy loves his new Maximus as much as I love mine. Like I said earlier: If only I could teach that Maximus to cook. Hee hee
-
Glad to hear you made your choice and have some good bonding time with your son. My own son (youngest kid) is turning 16 this week so I know how you feel!
Please do keep us up to date on your adventures!
-
I'm sure he'll love the Maximus Paul. I hope his health issues improve too.

:D :o :'(
Well it finally came in. We are both happy with it but it was off to a rough start. It came in on fedex while I was still at work. I ended up calling in the rest of the day not feeling well and went home early. Nothing a new dose of AG couldn't fix. :P
It came with air, around 800 psi, good, no leak. I filled the rifle up to 2000psi and off we went. The first problem I had was it was digging dirt in front of the target at 25 yards. I couldn't adjust the scope high enough to hit the target. Even with iron sights it was low. A slight adjustment with a barrel bend and that was fixed. I had it zeroed in in less than 7 shots using 14.3 CPHP. I had to stop shooting though. It was a little loud and it had already gotten dark. I had a light on the target though, I could still see to shoot but didn't want to spook the neighborhood.
The next day my TKO LDC arrived and we installed it. What a difference that dust collector makes. ::) I ran a few more shots though it and it was still doing well. I figured Ill do some chrony numbers and figure which pellet it likes best later. But fist I have to do something about this 15 stage trigger. Creek, creek, give,creek, creek, creek, bang.
I pulled the trigger assembly and polished everything up with some 600+ grit paper. I polished the hammer where the sear engages. Put a quick two screw mod on it. Now its much better.
No more creek, creek,creek........
Once I was done and happy with it, I handed it to the boy and wished him a happy birthday. He was all smiles. Loves the gun.
I took him to the range today to try and get a squirrel but nothing got close enough. we decided to shoot targets a while.
Now he is not a shooter,YET, but I'm trying to get him pointed in the right direction. I figured after his first shot at 50 yards and he drilled the bottom of a coke can, we had a good match with him and the riffle.
Once back at home Is where the story goes south. It was time to chrony and pellet test. I filled the rifle up to 2000psi and set up a target at 25 yards. Now at this point all I was really looking to do was get some numbers and find the sweet spot using the 14.3 CPHP. My plan was to shoot down to 1000psi and see how many shots I get and I wasn't after accuracy so much at this point. I had shot this target before so I just picked a pellet hole and started shooting at it.
Shot string starting at 2000psi
1. 841.0
2. 839.4
3. 838.6
4. 846.5 AROUND 1800psi
5. 844.6
6. err
7. 835.5 I'm pretty impressed so far.
8. 853.9 Shots are looking good. Im starting to think
about the JSB diablo exacts heavy 18.1.
I bet they are really gonna shoot accurate.
9. 839.1
10. 860.2 Around 1500 PSI
11. 853.9
I pull the bot back and it snapped off in my hand.
Chrony and pellet test done for now but the numbers and accuracy was looking good, even though I wasn't trying for accuracy. A loosely shot shot group pictured below along with dad and sons rifle pics.
I called Airgun Depot and they said they will get an RMA out to me right away. I'm going to call crossman tomorrow. I think I just want a new bolt. Ive already got the trigger where I can use it.
Oh well, such is life. He still likes it. Just have to get it going again.

Now about those pictures???
-
Thanks Paul. Nice pictures.

That's a nice B-day present for your boy, Paul. I hope he enjoys the heck out of it and you have my best wishes that his health improves.
On the issue of breech bolts breaking on the Maximus, does someone make a stronger aftermarket bolt to fix that issue?
-
Pretty disgusting metallurgy on Crosman's part. Now, who wants to complain about Chinese quality?
Wait a minute; on second thought, it's probably steel bought from China. When the steel mill my dad worked at shut down, he told me it was cheaper to buy and ship steel from China than they could make it here.
Please let us know what happens when you contact Crosman. Thanks!

On the issue of breech bolts breaking on the Maximus, does someone make a stronger aftermarket bolt to fix that issue?
Alchemy airwerks. David is a respected vendor on the forum. Get the stainless extended probe bolt, with a matching stainless handle. I have one in mine. You won't be disappointed.
-
Scott, that is good to know. I have not had an issue with my Maximus yet, but . . . .
Thanks for the post.

Thanks - I looked on his website and his eBay store but couldn't identity what I would want to order. Was looking for items specifically labeled as for the Maximus so perhaps I'm missing it since I'm new to Airguns & Modding.
-
David, I was just on the Crosman.com site. I was specifically looking to for the parts manual [not available YET]. However, it appears that the bolt used in the Discovery is shared with the Maximus. See Fig 1. ---> https://support.crosman.com/hc/en-us/articles/210136946-BPM22B-N-Owner-s-Manual-2015-Present- (https://support.crosman.com/hc/en-us/articles/210136946-BPM22B-N-Owner-s-Manual-2015-Present-)
A phone call to Crosman would probably confirm that the two parts are the same. You could still buy the nice one from Alchemy Airwerks.

;D ;D It is great to hear about father and son bonds and a love of the outdoors shared by them I took my son hunting fishing and camping from an early age and we still talk about it to this day and my son is 43 yo now soon to be 44. Being a good dad requires both love, understanding and a good deal of effort but well wrth the rewards of shared memories
-
I spoke with Crosman on the phone. They are sending out a new bolt, charging handle and O-rings. Great customer service.
I'm also going to look at that new bolt and carrier you were talking about in the threat above.
-
The bolt for the maximus is the standard crosman 22xx bolt. Same as the disco, 2240, 2260, etc.

Thanks for clarifying that for me. On the AlchemyAirwerks site, I found a page for Bolt Handles that has ten different bolts but the description's do not say what they fit. I can't post the link as GTA wont let me. I then found a SS Extended Bolt Probe in a different section that says "for .22 caliber 2240, 2250, 1322, BackPacker, etc". I'm assuming I would order that and say the SS Bolt Handle with Black Knurled Handle?
-
You are correct on the bolt. ALL the handles will fit the bolt you're looking at. Let your son pick the one that he likes best. ;D
-
Thanks, Scott - I'll just decide which handle I think I like best and order, hopefully eliminating the bolt-breakage problem altogether.
BTW, it's Paul/ShadowShot that has the son, not me.
-
Thats right, he's all mine.

How do you like the extended probe on your maximus? I had to change mine to a short one and when i looked under the breech TP, the skirt of the pellet is totally fwd of the hole. This makes to me easier to load a pellet, i don't have to push it toward the breech opening.
-
I like the extended probes. I don't have any problems with loading. I just roll the pellets into the tray, and close the bolt.
-
Update.
I drilled out the charging bolt from the bolt last night. I also had to drill out the #.05 Allen head screw that stripped out when trying to remove the breach so I could get the hammer out.
Polished the hammer, cut to length and field machine a new bolt to replace the breach screw I drilled out. Reassembled the rifle and used an actual bolt for a charging handle bolt until the real charging handle bolt comes in. I put the 2 screw trigger mod back in and set up. Its not an Mrod but it will do for now.
Now back out side for the final chrony and accuracy tests.
Im going to keep this short. I tried the 14.3 CPHP from wally World and the 18.13 JSB Exacts.
The accuracy between the two were to close to call, even with the jsbs giving a few more consistent fps shots. If I want to pay double the price and get shipped only to get just a little more FPEs, Ill get the JSBs. The CPHP 14.3 gives a little less FPE and I can get them anywhere. The over all accuracy was very close from start of the shot string to the end.
----------------------------------------------------------------------
Shots made at 25 yards starting at 2000psi shot down to 1000 psi. Both strings came out to be 22cphp to 23jsb shots.
The JSB 18.1 started at 745.1 fps. The max fps reached was 795.7 fps around 1500psi range. Everything else in the high range stayed in the high 760s to 770s. The795.7 shot was the only shot that high. Final shot was around 1000psi at 733.5fps.
The sweet spot was around 1700 to 1100psi.
16 shots
High at 795fps
Low at 753.8 last shot of sweet spot at 1100psi
Ave 768.18fps
Giving an average 23.76FPE.
-----------------------------------------------------------------------
Now the Crosmans
The CPHP 14.3 started at 827.2 fps. The max fps reached was 866.3 fps around 1800psi range. Everything else in the high range stayed in the high 850s to 860s. Final shot was around 1000psi at 803.7 shot 22.
The sweet spot was around 1800 to 1300psi.
12 shots
High at 866.3 fps
Low at 841.4 last shot of sweet spot at 1300psi
Ave 853.13 fps
Giving an average 23.12FPE.
----------------------------------------------------------------------
The JSBs did give me a more consistent fps and more shots (16) in the sweet spot, over all 23 shots in the fill. But I didnt loose any accuracy even with the looser fps spread over the entire 22 shots with only 12 shot count in the sweet spot of the cphp.
I had 16 shots Giving an average 23.76FPE with the JSBs
and 12 shots Giving an average 23.12FPE with the CPHP.
I think I will stay with the CPHPs for the money. The fps variance may be more but the accuracy stayed the same.
A few pics below.
Oh yea, my son who is still learning was very happy. He was able to hit a dime at 25 yards using the cphp. Made me very proud. ;D
-
Thanks for that report. Looks like your new Maximus is working just fine.
I'm thinking a new fancy bolt handle and a Boyd's stock and it will look like a $500 gun. Of course it will have cost at least $315 at that point. The Boyd's stock will probably add about a pound of weight too.
-
Is this what you recommend?
I just placed the order.
Teardrop Stainless Steel 1-piece Handle
and the
Stainless Steel Extended Bolt Probe for .22 caliber 2240, 2250, 1322, BackPacker, etc.
-
Paul, I would classify that setup as “functional ‘bling’."
-
Thanks, Scott - I'll just decide which handle I think I like best and order, hopefully eliminating the bolt-breakage problem altogether
Don Cothran (http://www.cothranmachine.com/ (http://www.cothranmachine.com/)) sells stainless steel bolt handles for $9.50 plus $3 shipping, cheaper than the $20 charged by others. I bought his cylinder shape bolt handle and it's a fine piece of work.

Shadowshot,
I've got a .22 Maximus arriving tomorrow. I hope mine shoots CPHP's as well as yours. They are so cheap at Walmart.

First item: I hunted the whole Squirrel Season (The Season of the Maximus! (http://www.gatewaytoairguns.org/GTA/index.php?topic=115550.0)) using Crosman Premier Box Domes. The accuracy was very good and I managed to kill most of the squirrels that I hit. I did notice that most of the head shots were “through and through” kills. So, during the season, I ordered a few tins of (softer) JSB 15.89 gr pellets and one tin of JSB 18.13 gr pellets to try. Today, I decided to give the Maximus a chance to sling a few of the 15.89 gr pellets at paper. The first two shots were side by side about one inch high. I give the scope 16 clicks down and tried a few more. Too much. I went back up about six clicks and the last five shots were on target. These pellets are very good out of the Discovery. They should be very good out of the Maximus too. I will confirm in May when the season starts again.
Second thing: The past several weeks, the Maximus has been leaking about 100 PSI per day. I discovered that the the air was escaping at the fill nipple. I tightened it about 1/4 turn and aired it up to 2,000 again. Two days later, it was holding the pressure. After the shooting today, I am down at about 1,600 PSI - I will shoot it down a little more before setting it aside until May. I like to leave about 1,000 - 1,200 PSI in both the Discovery and the Maximus.
-
See “Second thing” in the previous post. I ordered some O-rings from Crosman (warranty - no charge) and installed one below the pressure gauge. I cleaned the threads on the gauge block and added fresh Teflon tape to the threads before reinstalling the gauge block. I then removed the fill adapter assembly, cleaned it, added fresh Teflon tape, and reinstalled the assembly.
I filled the rifle yesterday and let it sit. It does not seem to be leaking. ;D ;D ;D
Even a blind squirrel will sometimes find an acorn.

I like my .22 Maximus a lot. Mine is not pellet picky at all and is very accurate. My main\only problem with it is getting to shoot it if my 14 year old grandson is around. He shoots it better than any of the other airguns I have, and always wants to shoot it. I have not put a scope on it as there is no real need, if either of us can see a target we can hit it. His eyes are better than mine though, I would scope it just so I could reach out further if he did not love it as is. We get 1" groups at 30 yards with the open sites, I wouldn't be very surprised if it was one hole with a good scope.
-
You are 61 - he is 14. His eyes are better than yours. Really!!! ;D ;D
I scoped my Discovery .22 immediately; and I did the same with the Maximus .22. Both are hunting rifles (Squirrels); and I occasionally reach out for one high up in a giant Oak. Accurate is the operative word here.
I hit the squirrels in the head most of the time. The rifles are both better than I am able to shoot them. And like your Maximus, they are not pellet picky either. I shoot JSBs because they are consistently accurate and the lead is a little SOFTER than the Crosman pellets.
Listen, go ahead and give the Maximus to that grandson and get another so you can both shoot at the same time. ;)

I tried to buy another Maximus yesterday but Crosman's coupon 20OFFTUESDAY would not work on my android tablet mid afternoon and at 9:44Pm when I got home it wouldn't work on my computer. Crosman's customer service reply was basically tough luck! better luck next time! I have bought many airguns from their site, most of the time the coupon codes work but this is not the first time their own coupon code didn't work. I am not happy with their attitude about their screw up, the code should have worked or they shouldn't make me wait for next time, I wanted it for his birthday!

I seem to remember something about a Friday special. I don’t remember the details though.
Perhaps someone else can provide more information?!

Not sure about the Friday free shipping special...
Supposedly, on Friday you get free shipping AND 25% off using AGNATION coupon code. I got the 25% off but not free shipping. I did order late here in Vegas so it may have been Saturday in new York by the time i sent the order.
The coupon will work for 25% off any day of the week. Only on Friday you're supposed to get the free shipping as well.
No idea when the coupon expires so order up soon!

Shadowshot,

I hope to hear a report on it. I'm sure it will be the same old boring stuff. "She not a picky eater and accurate.... blah blah blah".
Seriously, I know your going to love it. I hope yours does better than anyone elses here. They are great little guns. I love mine.

Your right, I didn't even think of the lead being softer with the JSB's. Most all my CPHP do a pass through also. Softer JSB's should keep most of the energy in the target. Will switch over for hunting and see what kind of results I get.
-
Paul, you may not have seen this one yet ---> JSBs 18.13 gr in different rifles (http://www.gatewaytoairguns.org/GTA/index.php?topic=124982.0)
It seems that when I went from the 14.3 gr to the 15.89 gr pellets, the hits seemed louder and the squirrels often were dead before they hit the ground. So, I thought that if the 18.13 gr pellets were consistently accurate [good groups, etc.], then I would maybe try them for our Spring Squirrel Season in May. The Discovery can handle them and will definitely blow a few at some unlucky squirrels next month.
-
An update on the Maximus:
That little rifle loves the JSB 15.89gr pellets. The accuracy with these pellets is impressive in the Maximus (and the Discovery). And it seems that more pellets are not going all the way through the squirrels I took this Spring. I like that since my hunting areas are in close proximity to residences. I will continue using the 15.89 gr pellets when the Fall Season comes around.
