How many of you use you Daisy 880 as a insect pest eliminator ?
Being that the Daisy can be pretty darn accurate and at short distances (~10yds with around 4-5 pumps) it would seem to me as a perfect gun for wasps, hornets, grasshoppers, cicadas and the like. I have not come across any such vermin yet in my area but those of you around water or in a wooded area I would imagine would have lots to shoot at that can keep you entertained for many hours. I'm going to start scouting around for older structures in the desert area that may have critters like this lurking around.
I think the Daisy would be a great gun for this, unlike a low powered barrel cocker, there is no main spring to lose its poop when cocked for a long time waiting for Mr. Wasp to land ;- ) The fact that if your intended targets range is shorter than 10 yds, three pumps may be all you will need, at short distances, a light, cheap, accurate pellet is the preferred ammo - no need for 10.5gn heavies here, a cheap 7gr lead will go out fast and shooting flat with just a few pumps ... perfect. A Crosman Wadcutter at 450fps still has about 2 fpe at 25 yards ... a CPHP at the same velocity has over 2 fpe at 45 yds!, more than enough for the critters I mentioned ;- ) If your gun shoots real cheap stuff accurately (as in some of the Daisy ammo or some of the Beeman) you are in pig heaven .. it is time to stock up on ammo and go on an insect safari !
There are a few insects I would try to leave alone like bees and dragon flies as they are beneficial, but I can imagine every once in a while one lands in the cross hairs !
What do you 880 guys think ?

Interesting...maybe once they thaw out ;)... but I would be more inclined to use bb guns for the last two (wouldn't want to use either one to tick off a stinger). Now if you mentioned lizards...
-
I do like to go bug hunting once the ground thaws up here. My go to bug busters are a D 722 pistol and a D 74 BB rifle. That last one shoots as fast as you can pull the trigger. You can "walk" the BB's to a flying carpenter bee. I never thought of using an 880 for bug hunting. I do have an 822. Should be at least as accurate. I'll give it a try......in about 4 months. :-\

As an herpetologist at one time, all reptiles and amphibians are off limits for me ... I consider them friends ;- ) they eat a lot of harmful stuff and IMHO are pretty cool. I had a collection of rattlesnakes too, but gave them to the zoo as it was just to dangerous to have them around.

Head shots on a couple inch reptile w/a head bout the size of a pellet is pretty cool also. ;)

The one and only time I was ever in Roswell NM, the roads and parking lots were covered with Horned Toads.
Talk about a target rich environment!

That's pretty funny Dennis & doesn't surprise me in the least. I will take an occasional run of the mill lizard with the 880, although HT would be hard for even me to shoot at. Those little guys are pretty cool.

Those little guys are pretty cool.
When I was in grade school in the '60's here in Denver we used to find them in an open lot across the street from the school. Those along with some little lizards about 4-5 inches long. Have to say that I haven't seen a single one of either in over 40 yrs. though.
We'd bring them into the classroom and put them in our desks. Teachers freaked out about it.
We used to think that the yellow belly HT's were poisonous. To this day I still don't know if that's true (and at MY AGE!!). ::)
-
Though I have not tried any bugs but slugs with the 880. I did get headshot on a jumping spider at 8 yards with my 1322 at two pumps using Meisterkugeln. I would assume the 880 would be a easy bug killer, it sure pops slugs easy.

LOL, Now that's what I call accuracy! I LOVE IT!!

You are correct. The YBHT secrets a toxin on its body to ward off predators. I've never seen one here in NM. Those I might take a wack at. ;D

That little critter should be preserved. That was one heel of a shot! I take it you avatar was taken shortly there after. ;)
Shoot the 880 can easily take down a rabbit with a head shot. My youngest son took a Jack Rabbit at 35-40 yards with one. He kept telling us it was skill... ???

I try not to kill anything that's helpful or just plain cool. No butterflies, honey bees, dragon flies, bats, snakes, toads, frogs, salamanders and etc. That leaves plenty of actual pests. Got two starlings off our bird feeder today. 8)

Yes that is exactly the face I made when that spider dropped. I thought at the most I could hope for is it would turn her into a spot on the wall. I was totally shocked to see the head missing LOL

Ahhh, another good reason for me to go ahead and get that “bug buster” scope i’ve been thinking about for one of my 880’s.
Should focus right in on those close range carpenter bees! :D

Bug buster is nice on the 880, but cost more then the gun LOL But you can bust some bugs

Paulus,
It would be the first time in my life (65 years) that I paid more for the scope than the rifle if I do it....a lot more!
Lol, it does kind of go against the grain for me.
Thing is, these little rifles have proven accurate enough to justify doing it.
Real happy with my 3x9 Barska and 4x Winchester scopes too though... really all that’s needed.
These little 880’s will make a fella go overboard if he does’nt watch it lol!
-
They shoot so nice, the bug buster just makes them real handy. Here is mine, but sadly that scope was only on temporally.
-
Wow Paulus.... it looks great with that scope on there.
Thanks for making me want one more lol!!
-
These little 880’s will make a fella go overboard if he does’nt watch it lol!
The thing to remember here is that although an 880 is an inexpensive gun, it shoots like a gun that is 2,3, 4 times the cost! That alone (for me) would justify putting a nice scope on it.
Then again, I'm one those nuts who takes a $60 Crosman 13XX and by the time I'm done with it I have $300 or more into it, but again, after all that, they shoot like a +$300 gun after my mod's.
Just my thoughts.
-

That is a nice looking set up ... does the 880 have a scope on it now or is it an iron sight gun ?
PS: did you do any power mods on that gun or did you leave it stock ?

I agree 100% on both counts... the 880 and the 13xx.
They both far out shoot their price tags, along with a few others out there too on the low end of the price tree.

My late model 880 is highly modified & can give any of my pumpers competition. I attribute most of it to it's hair trigger. Here are a few bulls at 10 meters w/open sights...

Since I do 99% of my shooting at night in the dark I must have a scope. So yes it does have a scope. It has the 3x9 center point that came on my trail np2 on it. The LDC is GEO and really makes things nice. I have not done any power mods. For me I cant hunt with air rifle in Washington. So I pest with it, the stock power at 10 pumps will more then take anything I would ever need to.

The Bug-A-Salt Lawn and Garden guns are the best "Insect Removal Tool"!!!
I killed about 25,000 insects last summer. Yes, 25 thousand.
I wore out 4 Bug-A-Salt Lawn and Garden guns.
They shoot about 6,000 times before they stop working, then Bug-A-Salt will replace them.
I sprayed the siding on my shed and my yard fence with hummingbird food and the ants and bugs come by the hundreds.

My late model 880 as stated earlier is highly modified; straw barrel encased inside of an arrow bolt, front sight altered to accept the added diameter of the arrow bolt, bolt & straw barrel cushioned above lever arm pivot point, plastic receiver clam shells bolted in place, added weight to both stock & forearm grip clam shells, & highly modified the trigger & sear. With all this said I recommend you only modify the trigger & sear & add weight to the forearm grip & stock. These are the only mods I will explain at this time & here’s why; the stock trigger assembly is atrocious & there is no weight to speak of to help balance the gun. There is no way you can group shots consistently with these two factors alone. Once you’ve addressed these two issues, & I say this with the utmost respect; learn how to shoot your guns.
That last comment is a tough pill to swallow as it was for me. I knew all there was to shooting guns & no one was going to tell me otherwise. It wasn’t until I spent time over at the “Shooting Match Gates” that I realized I didn’t have a clue the skills necessary to achieve the results l was hoping for. I was dumb founded as to how those members could knock down bulls the size of their pellets day after day like they were the size of dimes. It took a lot of time at the range to finally piece it together.
My recommendation at this point is to read the information on this link (https://www.gatewaytoairguns.org/GTA/index.php?topic=140500.0 (https://www.gatewaytoairguns.org/GTA/index.php?topic=140500.0)) & spend a lot of time on the range putting each step into practice until it becomes routine. To barrow a phrase from a wise man; "until you master these steps you'll be spittin in the wind". My apologies if I've offended anyone but I have never been one to tip toe through the tulips. ;)
In the mean time I’ll gather up those two mods which are scattered everywhere in this gate & post them here.

Here you go Dennis. Since there are no short answers I'll go ahead & explain it here;
Increased the angle of the drop off which shortened the ramp, then buffed & polished the entire trigger assembly to remove all casting burrs. Also streamlined the trigger.
I used needle files, then wet & dry fine sand paper (all under high magnification), & finished them off with my power buffer & wax polishing compounds (jewelers rouge).
My recommendation is to keep assembling & disassembling until you get the pull your after. Do not change the pitch of the ramp. It will be shortened while increasing the angle of the drop off. Make these alterations all the way to the face of the hammer. If not, the trigger will hang up & will not roll off the ramp as it should. Use caution because too light a trigger pull is just as bad & obviously much more dangerous!
-
I would say fun but not effective, hehe. Big furry pest require traps, small insect pest require spray!
-
Adding weight to the stock is straight forward. IIRC it takes about a tube of silicone.
As for the clam shells; fill to the edge of the support veins. Let the silicone begin to set up. Reinstall both clams right before the silicone hardens. It will form its own casting. Not the prettiest but it works.
-
Thanks Marty.
All I've done so far is to remove the leaf spring and file the 45 degree angle on the sear contact, leaving enough flat on top for a secure lockup. Also polished all contact areas. Right now I'm happy with mine.
After you filled the fore grips, did you dig out where the metal tabs insert/slide into the center spine? Otherwise, I think they would be loose, as the only other attachment is the front screws.
I have one plastic and two metal receivers. Where/how did you "bolt" the clamshell halves?
-
You are welcome Dennis.
This mod is only for the late model 880. The center keepers for the clam shells ride above the surface so the silicone is not a problem.
I have since purchased a couple of nice metal receiver 880's & are night & day compared to these feather weight late models. Plenty of weight on those. I've had so many coals on the fire lately that I haven't had a chance to run them through their paces aside from an occasional plink, but there is no doubt they will be a far cry performance wise from these late models. I doubt I'll do any mods on those...their that nice. ;)
...Oh ya...that flat spring was the first thing to hit the trash.
-
Agreed, the metal ones are much nicer. Only issue I have is that little pad that the barrel rests on at the TP. If those were still available the world would be a nicer place for older 880's. I like the screw-in valves also. Wish I had a lathe to try fitting a larger OD barrel. Some metal ones are smooth bore.

Thanks for that. It's good stuff. The day I stop reading, stop seeking advice from those who know more than I, start thinking I know all I need to know, is the day I becoming a closed minded dingle-berry.

Work has been driving me nuts, so I have not had a chance to do anything 880 related. I very well may try to pull the rivet that I have in place of the factory probe and install a longer one to see if my velocity issue was probe length related by not pushing the pellet totally past the TP, thus causing pellet interference with the air.
I hope to do this Saturday, so maybe I can get out and find something to shoot on the desert floor the rest of the weekend.
It is to cold for insects to be out, so I'll keep an eye out for an occasional Starling or maybe HOSP.
It sure is funny, with all the 25-60+ fpe airguns I have, I'm getting a kick out of these inexpensive Daisy's.

You were really on a roll there for a while. Hope you're not going through withdrawals. :o

Though I haven't actually tried shooting insects, I do find that, going to a very small target (bullseye with a marker pen), or using the scoring numbers on a target for a bull, I get some of my best groups.
-

Thanks Stuart. I think if folks are serious about honing their shooting skills they should spend a lot of time on the range putting those tips into practice. Without a doubt it can be extremely frustrating at times but once everything falls into place it is very rewarding. I have hesitated getting back into the shooting competition because it does take a tremendous amount of time, commitment, & discipline. On the flip side the rules are very lenient. You have a lot of time to shoot at bulls & only post your best round/rounds.

For testing this just use a bent piece of wire to push the pellet in a little further. That way if the probe length isn't the problem you can leave it be.

Lengthened the probe by another .085 and it made a difference of 20 fps with the 540fps gun ... so now I'm getting 560fps ... great ?
I'm going to put a shim under the hammer valve area to get more lift on the valve.. I ordered some .030 and .040 shim material, should get that tomorrow >

Is this the same gun that you were getting 580-590 fps from w/10.5 gr ammo? If it is, there might be something else going on because changing the probe shouldn't cost you any power as long as the TP isn't blocked. I seem to remember you mentioning bolt O-rings but cannot recall what was said, but have you tried the tissue/talc test to see if it's blowing back at the bolt?
Anyway, just a thought and good luck.

Yes it is, Since I changed the probe things went south with this gun. I will do a powder check tomorrow, although I did a toilet paper check and did not see air blow by ... except ... I felt it on the underside of the gun ?
I did not buy any small bolt "O" rings today as I was waiting for my graphics guy to tell me if he needed any "O" rings for our Roland printer. I will buy the rings tomorrow "Heck or High Water !!!"
He made some PETG slit washers for the hammer to lift the valve higher. I used A blister pack plastic of .025 thickness .... I ordered .030 and .040 from McMaster Carr today !! I will probably use the .040 thickness, as all my measurements indicate that thickness will work. A .04 higher lift SHOULD let a lot more air past the valve head and into the TP quicker, equating to higher velocity ----- We will see !

If this was a brass compression tube gun I'd suspect the barrel had gotten turned a little causing the TP to not be in perfect alignment w/the valve body but that's not a problem w/the aluminum tube guns.
Are you going to do the high lift mod before you sort out the power being a little off? Really doesn't matter that much either way, in the bigger picture as long as you get the power where you want it, it's all good anyway!

Bought the "O" rings a few hours ago and will give that a shot when they come in. He made a few split ring washers of .025 so i may try those. Will do a powder test tomorrow for sure. The only other thing I wonder is, this gun I believe has an old style flat piston .. I wonder if I should install a new piston and fill with JB Weld. I measured piston length before and they seemed to be the same, but this was a US made gun as I remember ?

Anyway, just a thought and good luck.
If this was a brass compression tube gun I'd suspect the barrel had gotten turned a little causing the TP to not be in perfect alignment w/the valve body but that's not a problem w/the aluminum tube guns.
Are you going to do the high lift mod before you sort out the power being a little off? Really doesn't matter that much either way, in the bigger picture as long as you get the power where you want it, it's all good anyway!
Bought the "O" rings a few hours ago and will give that a shot when they come in. He made a few split ring washers of .025 so i may try those. Will do a powder test tomorrow for sure. The only other thing I wonder is, this gun I believe has an old style flat piston .. I wonder if I should install a new piston and fill with JB Weld. I measured piston length before and they seemed to be the same, but this was a US made gun as I remember ?

Well that did not work out so well, the washer looked good, but the spring did not have the force to push open the valve poppet ... So I was walking around the shipping area with a airgun with 900 plus psi in it until I dismantled the gun and released the air ... phewww .. I was on edge for sure !!!
I'm going to look and see what McMaster -Carr has in springs !!!

Well velocity is staying the same even with a .060 shim under the hammer spring. I put a .025 shim under the poppet valve and that made no difference in velocity, this gun is a problem child.
Here are my readings on the Black 880 using 10.5 gr Crosman Premier Heavies.:
9 pumps - 562 fps
10 pumps - 581 fps
12 pumps - 607 fps (I never do 12 pumps, but with this gun I don't feel it pumping hard !)
I will work on the Brown 880 tomorrow by adding a .060 washer under the hammer spring and a .025 shim under the valve poppet !
See you tomorrow (If I can wait that long) ;- )

Just worked on the Brown 880 ( knew I could not wait a day).
Put a .060 shim under the hammer spring and a .025 washer under the poppet valve, here are the results with 10.5gr Crosman Premier Heavies:
9 pumps - 578 fps
10 pumps - 596 fps
Did not pump it more as it felt like it had pretty good pressure. Will shot it some more tomorrow, and re sight it in !

Good deal. Now, is this with the "short" finishing nail probe or has any of that been changed?

I used a 3/32 rivet and have a probe length of about .285. It shuts off the BB port but it actually makes loading easier as the thin probe is used as a guide. Loading lead balls is very, very fast also.
Will chronicle lead balls and report back after I do testing at work tomorrow.
I will decide on what velocity I will use for the lead ball based on a ~ 15 yard range.
We will see tomorrow !

My mistake- I forgot you said you already lengthened the probe by 0.085".

I kill jumbo cockroaches with a Daisy 105, but never tried it with a pumper.
I do it at night in the summer and like the quietest gun possible.

They come in from the fields and I gotta keep them from entering the house.
Chemicals could do it, but this is more fun and is effective enough.

I didn't shoot roaches, but I used to shoot caterpillars off trees when I was a kid with my 105 ;- )

Well I played with the 880's today and had to remove the shim under the valve poppet on both as I was getting about 10 fps lower fps than yesterday, as it stands now both guns are getting as follows ( within a few fps as I rounded off to make things easy as I made notes on stocks for field use):
Blacky:
11 Pumps ~595 fps 10.5 gr CPH
8 Pumps ~585 fps 8.2 gr .177 cal Lead Balls
Brownie:
10 Pumps ~ 596 fps 10.5 gr CHP
7 Pumps ~ 583 fps 8.2 gr 177 cal Lead Balls
Blacky has an older style cast piston head and there is a ~ two paper think ring on the face ... that may be the reason I'm not getting the speed of the Brown 880 ?
What I do need is a Code # for the hammer spring replacement. I just don't want to stretch it out, I want a bit more powerful one .... maybe another smaller powerful spring on the inside of the stock spring, I don't know. McMaster-Carr has this part # 9657K288, but its a little big, but it may work ... just wondering if it is too strong ?
Here is a picture of my problem child acting as if she is "Cool Beans"

Well, it's a looker!
Have you been to Ace? You might luck out for a stronger hammer spring, Most have a display board showing their spring selection w/the corresponding bin number.
-
I was just gonna suggest Ace Hardware.
FYI - Ace hardware stores are franchises and they don't carry the same brand springs from one store to another. You may have to start out at one store and if you don't find what you need, note the brand of spring hardware that that store carries. Then call some others to see if they carry a different brand. I have to shop at two different Aces myself to find what I need, sometimes for the same gun (but the springs are used in different locations on the gun).
The same thing goes for those little specialty hardware bits and pieces bins.
Like Mark said some Aces have springs in organized bins with the number on them that corresponds to a chart or booklet, but some others just have them in carded baggies hanging on hooks.

That's good to know. I'm lucky to have a really good Ace in my little town, been owned forever by the same family. The people that work there actually do help most times when you ask them something- imagine that! They even have taps to go with the odd thread count firearm fasteners.
Wll, if you measure the spring OD, free length, wire diameter and coil count you can use an online spring calculator (http://www.acxesspring.com/deflection-of-compression-extension-and-torsion-springs.html) to plug the numbers into to get the spring rate. General rules of thumb for springs: a smaller OD, less coils and larger wire diameter all (individually or collectively) gives a stronger rate/ stiffer spring.

I will check that out tomorrow and see what I can find out :-)

I muzzle load my 880 with a spit wad of tissue paper, then turnip seed for shot, then more tissue to hold it in place. I use coated electrical wire for a loading rod. I wing shoot yellow jackets out to about 6 feet.
