It was a good experience buying from Flying Dragon Air Rifles, I bought the Sentry model 705-9K in .22. I ordered the gun and it was at my door 2 days later, it came with five shot target at 10 yards, a note showing different velocities of 5 popular pellets at around 2400psi. It was a super good deal IMO for $310 to my door. I was expecting it to be an automatic safety which it's not and I'm very happy about that. The fit and finish on the gun is very nice. It's going to be a while before I get inside of this gun because I presently have been getting my M11 the way that I want it.
One thing I'm going to be adding to this gun soon is a scope and I'm seriously thinking about a nice one that FDAR offers at a remarkable price.
Here's the shot string the way the gun came out of the box with the power setting on 3.

After the first chrony string I decided to turn the power adjuster up to #4
(https://i.imgur.com/TqHuhAU.jpg)
I'm thinking this gun has much more potential by opening up one or more of the ports it, I've never been inside of one of these and I've no doubt it'll be a rewarding experience.
I'll be heading for the woods in about an hour with my M11 trying out a new LDC for it I recently bought from Rocker1.
-
Seems pretty impressive Wayne. :D
Now that I have a chrony I need to play with my Sentry's power setting...
I have one on FDR's Rex scopes on my XS60 and am very impressed with what you get for the money!
-
Haj did a review of the JSAR Hawk which is based on Sentry and found that transfer port going into the breach were mismatched and used 3/16 drill to open up breach to increase power 15%....check out the new Haj gate and JSAR gates and find a great deal of info and discussion of that "potential" these guys have once they are opened up
-
My old .22 Sentry just needed the barrel and transfer port opened up and I went conservative on that IIR .175 is what I bumped it up to, with amazing results.
They are pretty basic to work on similar to the SnowPeak guns.

Scott you're not the first person I've seen that had good things to say about those scopes. I will be buying one soon, maybe even after I type this up. I'll kill two birds with one stone and order scope rings with it too.
-
nice shot strings wayne, i love the sentry sidelever, smoooooth cocking
haj's video on the tear down and tp mods would be the same, barrel is different, valve different
the thing i really like about the side focus bubble scopes he offers is the light, that light blue really brings out detail in the brush line under low light, great for dark cedar patches and early/late day hunting
-
I just did another Chrony test, this time I set the power at 3.5 but on the first shot I hadn't reset the power yet, the rest of the shots were all at pwr level 3.5. I appears that the barrel is leading in and sealing better already with only 106 shots through the gun. These numbers are looking better yet IMO. This gun is going to make a dandy squirrel gun for sure . . . . cmon warmer weather, it looks like next week is supposed to get up into the 40's with some sunshine, that will bring the squirrels out !!!

Zeddymon the medium height 30mm rings didn't work out on that sentry well so I ordered a 3-12x Rex from FDAR and it came with 30mm tall rings, I ended up using the medium rings with the 3-12X on the Sentry and am going to use the tall rings mounting the 16x on my M11. That rifle will be ideal for shooting across the fields that I hunt for Ghogs, also I plan on trying for some stealth coyote hunting in early spring as well. I've never shot a coyote and even the DNR said they needed to be thinned out there. I must say though that I'm really happy with how well my Sentry .22 is performing, it's very accurate and fun shooting, I still haven't seen any good shots on squirrels since I've finally been out with it but I sure the heck will when we get rid of the snow, squirrel season is open til the end of March here.
I did a short video clip of a three shot group that was about 45 yards, I sure like the way this gun shoots, for being a gun that's not regulated I sure get a lot of shots with it. During this stormy weather we've got coming here I'll be doing another chrony string with it soon plus I'll probably be doing some more casting pellets and slugs.

Nice group Wayne= That will get you some squirrels for sure. I'm thinking of getting one of the new 705 Sentry's. Like all Chinese moderators i'm guessing the factory one doesn't work to good? Does the barrel have 1/2 x 20 threads? How do you get the factory mod off?
-
Pat to be honest I haven't had mine apart at all yet, the only thing that I've done is adjust the power up. It is not REAL loud but could very well be muffled down some if a person wanted to use it in suburbia however I only use most of my airguns on State land here in Michigan where it's mostly PB's that people are using and out there it's rare that people even hear me shooting. I might ask David about what he might have that would work good on one of these but for now it's not a critical thing in my case. I really had to get one for my M11 because it was as loud as a .22lr shooting straight from the barrel like it was, now it's mousefart quiet @60+fpe.
-
i have also been very happy with the sentry's, wish i had as much time as you do to hunt.........i've been doing birdfeeder protection from the red squirrel menace and fixing barns for the farmers
-
Wayne= Your a lucky man to have state land right out you door. Yes i am in suburbia so silence when i shoot in my yard is my number one goal. I know i can find a moderator to fit. I was just wondering how much of a pita the factory one is to remove.
-
While I can not speak for Wayne, Or the new 705... my 702 Sentry is fully shrouded and is very "Back Yard" friendly.

-
FYI the 702 does get louder when you crank up the power. ;D
-
So do I...
LOL
-
I like the looks of the full shroud on the 702 better then the little moderator on the 705. I will have to call Mike & ask if they are interchangeable. The selling point for me though is the side lever. Just feels so much more natural then a bolt. Just a personal preference.
-
Much agreed Pat, I LOVE a side lever... I have been waiting for a reply from JSAR, the maker of the Hawk / Night Hawk, for parts for the side lever conversion for over a year with no reply.

OH DARN... He is our new Administrator... :o
-
And a good one he is!! Unfortunately i would not hold my breath waiting on that. Im sure JSAR is just going to get busier & busier with new projects. Which is actually great for all of us. Now if only i could find a way to supplement my social security.
-
I might ask David about getting something to quiet mine down because even in the woods it's loud enough to let the squirrels and other critters know where the shot is coming from. I have mine set to 3 1/2 on the power adjustment which is really plenty in my opinion for the .22. I will be taking apart my prototype .25 because in reality it's not shooting the 26 grainers that I cast as fast as I'd like it to and I know that it's more than capable of getting the speed up considerably, it too is a 705-2 but it's bolt action. From what Mike says on his web site the 705-2's are more powerful. I don't think the $270 model is side lever but I could be wrong, it doesn't say anywhere on his site if they're now sidelever or not but I can tell you the side lever on the new HC is the cat's meow no doubt.
-
Lots of info online about the 702 sentry but not to much on the 705? From what i have read the 705 has a longer barrel,longer air tube & the side lever. I haven't read any bad reviews about these guns so that's good. BTW i see that HUMA now has a reg for the sentry.
-
Wayne= Your a lucky man to have state land right out you door. Yes i am in suburbia so silence when i shoot in my yard is my number one goal. I know i can find a moderator to fit. I was just wondering how much of a pita the factory one is to remove.
it is a pita to remove, hard factory press so they can't be removed from barrel, i did it to one of mine, its really barks now but is much shorter than the air tube, i will never get it back on and now i need to re-do a shroud set up for it or hope mike comes up with another barrel
sidelever and bolt action have slightly different barrels by length, bolt one will not slide in fully into sidelever
-
Zed that is a bummer that it's press fit on on barrel, I guess the LDC thing is pretty much out of the question then ???
-
Zed= That's what i was afraid of. Did you eventually get it off with heat? Could someone tell me the O.D. of the barrel. Donny fl makes slip on adapters in 10,11,12,14, and 15 mm . I have used one before & they work.
-

.22 barrel OD is .545 in seems enough meat to thread for adapter, lets not talk about how i got it off it wasn't pretty, just good enough to not damage barrel, did size a tube to fit over the old shroud for temporary use
-
here is what it looks like.......i did a custom stock to convince the boys at Xisico they should have some stock options available for a more traditional look
-
Zed= Thank you for the info. I'll have to see what i can come up with.I like your blond stock as opposed to the dark stain they come with. I also had a hard time getting one of those press on moderators off. With the barrel in a padded vice i heated it with map gas & had a pipe wrench on the moderator & it wouldn't budge. I finally put the barrel vertical in the vice and put some penetrating oil in the moderator & the next day it broke free.
-
After reading this thread I started looking into those REX scopes. Does anyone know the weight of the REX 3-12x40SFB? I cant seem to find that info anywhere.
-
I have one but I hate taking it off my gun because it's sighted in perfect. I looked the paperwork over closely and the box too but there's no weight anywhere. It's no where near as big as the Rex 4-16x which is probably 23 oz's, my Ohaus scale maxes at 22 oz's and I was just about to release it on the scale when it went over 22. The Rex scope is not made for a break barrel though but I actually had my gun leaning on a tree, it fell and the scope was still right on the money. I was really worried about it so I looked everything over real close to make sure everything was ok.
-
I was doing a search trying to find the weight of these Rex scopes a guy said that the Rex scopes are actually Schmidt and Bender or Swarovski brand that have minor flaws or cosmetic damage and can't be sold at a regular cost of $1600-$2200. He said that REX actually stands for Reconditioned, Extremely X-pensive
-
That's wild! Thanks for searching for the info.

that is right wayne,......i have never seen issues with the glass or reticles, mostly they are built to the same quality as sample batches for the makers, who then make changes to their liking before they get a stamp of approval

Pretty darned cool to be able to buy a scope at the REX price rather than blow a wad on a really expensive scope :D

From B.B Pelletier
"Rex scopes
Pyramyd Air has added the Rex line of scopes to its scope line. These optics come from the same people who bring you the BAM air rifles; (China) and from first examination, they appear to be just as well made. Today, I’ll take a look at the 10-40×50........"

-
yeah the acronym meaning is a joke, but the principle remains they are made for "brands" i don't know which currently, they are high quality, just tighten your screws, i have lost a focus screw and have had a turrent screw slip past on adjustment, just needed to be tighter
-
I did another chronograph pic/string with my .22 Sentry 705-2 this morning, this will be probably the last one that I do until I modify the gun which might not be too far down the road because with these guns I doubt very much whether I'll ever need to get warranty work done on this gun. They're really built very well and I'd be willing to bet that Mike gets very little warranty work in comparison to a lot of other pcp's that end up needing it. I sure am glad I made the decision to buy this gun because I'll more than likely be shooting it a lot this year.

Does Huma make a regulator for these guns ??? Having a regulator in one would help considerably for the loudness IMO, I'd probably regulate the .25 to about 2200 to 2300 psi, I think you'd have good energy at those pressures once you had the ports opened up some more, the baffles in the permanent moderator would probably be sufficient enough to quiet it down. You could also back off on the hammer as well at those pressures and probably not be using as much air per usable shot.
I was out shooting the prototype today shooting some slugs that I cast and sized up this morning and I was very surprised and happy with the results, even with that little Bugbuster that I have on it it was giving me some very good accuracy, I'm convinced that opening up the ports another .020 is a must so this gun is more adept for shooting the 35.3 grainers that I cast up this morning, the weight of them is very consistent with not very much variation in the weight. I'm going to do another couple casting sessions of the BBT's very soon knowing what I know now.

lane makes a reg for it, and huma
-
i removed that plastic thing on the muzzle and had all but one barrel port closed and had the lead-in done, as there was none before...... ::)
also cut, threaded and crowned the muzzle for a Rocker1 LDC.
different gun now !!
stability at high speed, 1000fpe with 14.3gr cpd eight touching at 35yrds.
no matter what some folks say about ".22's cant run over 925 accurately" ::)
this one does very well.
yep, it would be nice if there was a traditional stock available for the gun.
as for the rex scopes......i have a 30mm 3-12x40 SF that sits in its box, and can be had for the right price ;)
-
John that is a big improvement over the stock LDC and I'm sure that it's much quieter as well. I'll bet that the 217 BBT hollow points would shoot really good from that gun the way that it is right now. I'll be trying them soon in my .22 also and I'll let y'all know how good they work from it.

I was the one that worked with huma to develop a regulator for the sentry two years ago in my you tube video https://youtu.be/sFbmPwZDZ2Q

Very nice 702-3 ya got there Ken, that baby is accurate no doubt. I just recently opened the ports more in my .25 Sentry 705-2, it's not a lever action like the new ones but it's got the airtube like the new deluxe models with the gauge up in front. Even the wood stock and polymer fore stock are what the 702's had and have the hole in them for the gauge but there's no gauge block in the tube. I opened up the ports more yesterday and did a 28 shot chrony test with it today.

Looking good Wayne 👊🏾😎 give a huma regulator a try works good in mine
-
A couple days ago looking through my pellet supply I decided to try turning the gun all the way up and put some 23 grain magnum hunters over the chrony. The new side lever breech does cover up most of the #5 mark but it's on there. I was looking real close through my Optivisor and could see parts of the 5. This will be the next gun that comes apart, on the .25 the hammer spring did need some deburring on both ends and I think that it did make a difference comparing before and after. I'm also curious how big the ports are. The port that was on the .25 was very small, it's now 3/16". I made a TP from delrin for it that works great.
I started with 3K and ended at 1.8K pressure.

-
Wayne, the more posts that I have read about the Sentry the more impressed I get. I should weed out some of my .22's and pick one up and the new full shrouded models look and sound great. The problem is that I have too many pokers in the fire and can't get out of my own way. Bob
-
Bob this has the most out of the way side lever I've had on a gun too, it never gets snag on clothing or anything, I've yet to have it pop open at all when I'm out with it. The last time I was out with it I dug at the bottom of my coat pocket and found a BBT to try in it, with the scope adjusted for 19.6 grain pellets the 27.5 grain landed about 1/4" low and to the right(probably 30 yds) from where I'd just shot a 19.6 grainer just before it so I've got a sneaking suspicion that the gun is really going to shoot them good. Well I have a pot of lead and ladle that are probably up to temp right now and I'm going to cast up some BBT's in 25 cal. Both of these Sentry's that I have are eating the BBT's without being sized which also puts a grin on my face :D
-
Hopefully this will be the last chrony string before opening up this gun for mods maybe soon I've got the scope zeroed real good at this setting and pretty much know right where I'll be hitting.
(https://i.imgur.com/VC5q2ck.jpg)
These guns really are nice for the cost of them.
-
Dagnabit, you guy's - I'm trying to wait for that new Air Venturi Avenger to come out but every time I see you all posting about these Sentry's, I want to call Mike up & buy one!
-
That Avenger sure looks like the ATI Liberty to me ???
-
That's not a bad thing, is it? The Avenger just seems like a whole lot of rifle for $300.
-
That's actually a great deal IMO, Airventuri is a very reputable business too and your support there would be really good if you needed it.
-
I did do a more recent chrony string shooting the BBT's from my Xisico Sentry 705-9K and have also been in the woods with it since. Now that I know just how good the gun is shooting at present velocities I think it's finally time to get inside of this gun and make it breath, I'd like to get in the mid 800's with it which I'm sure that I can. The thing that's nice about these guns is the hammer spring that comes with them seems to be ideal for this gun in general and I think that it work well with the ports opened up also.
In the woods shooting slugs is a joy with this gun, super accurate the way it is, I can watch the slug flying straight as an arrow with a little elevation change out at a distance. I've got it sighted in for 40 yards right now and have already gotten some red squirrels with it, last outing I got two and nailed the first one in the head big time.
(https://i.imgur.com/Fag2dQ3.jpg)
The rain has stopped here and I'll be heading out in at daybreak (warm this morning) and I'll be bringing along some bug spray for the ticks (they're really bad this year). I'll be using the .25 cal Sentry shooting slugs, I'm going to start at a spot where I've seen ground hogs in the past but there's also red squirrels in the area. I've also seen quite a few possums at that spot as well.
-
Wayne
Looking good, I'll be following along behind with my 25 also............. ;)
Providing my supplies get here............... ::)
Have you run the power adjuster thru it's ranges, I am going to do that with my 22 Sentry,
hoping I'll be able to have a power range by changing the adjustment wheel etc.
Thanks,
Don
-
Don I would imagine that your .25 will have a lot more power than mine had to begin with because I found out that the prototypes had way too small ports in them, there were about 20 of them all together I guess.
-
Thanks Wayne
I was wondering,
when using the WC pellets (22/25 cal), if the power adjustment wheel would provide enough adjustments, read accuracy,
that when using WC pellets, power wheel set at 1.5 and heavy weights slugs power wheel set at 4.5 etc.
You would have to play around with the adjustment wheel to find the accuracy spot for each pellet/slug you are using etc,
but that would be nice to have that type of adjustment for any pellet/slug you wanted to use etc.
I'll have to look at the power wheel and see if I can add some numbers to the face side I can see etc.
I can't wait for my order to get here......................... ::)

I got to thinking about my .22 Sentry with the side lever that has the bleed block in the air tube and that's when I decided to do a complete teardown of it and it's probably a good thing I did because it had more than one loose bolt/screw holding it together. How I got the bleed block out of it was I bonked the tube on a piece of wood until close to the front of the tube, then I used 120psi pressure from the compressor nozzle into the hole in the tube and it pushed it out. Then I was able to loosen the cap to the valve and take it out. The Transfer port on it is about .110 (cheap harbor freight caliper), before I assemble it I'm going to drill the valve exhaust, transfer port and breech all out to 11/64" (aproximately .172). I'm sure that bleed block is probably the same one they used on the originals for the gauge ??? I'm sure that MikeM has just the tool for removing that bleed block which threads into it which would enable you to pull it out rather than using air to push it out. Also one of the barrel o rings was sheared too, I'll be taking my time reassembling it making sure I remove all unwanted burr's throughout.
Going from .110 to .172 will make a considerable difference the way the gun shoots without a doubt. Actually now that I think about it the transfer port that I have from my other Sentry is drilled out to .172 already, I'll use that instead and just drill out the valve and hole in the receiver.

Wayne
What does the poppet seal look like?
What dimensions are the poppet head/valve stem etc?
Inside diameter of the pressure tube?
Approximate cc's of the pressure tube,when all parts are in?
Diameter and length of bbl?
Did you also do the other end, any chance of adding numbers to the power wheel?
Which screws were loose and where were they?
Thanks,
Don
-
The poppet seal looked good, I didn't measure the poppet or stem, right now the tube assembly is back together with ports drilled out to 5/32" instead of 11/64", reason being I'd have had to drill off the shoulder of the TP and I didn't feel like making another delrin TP at the moment. Just got done deburring the hammer spring which had really sharp ends on it but not anymore. I've got the tube pressurized to about 2700psi and I'm going to let it sit over night before I assemble it the rest of the way.
-
Thanks Wayne
Was that #36 screw loose? the one you advised ti use Blue Loc-tite on......... ;)
Don
-
I was doing a search trying to find the weight of these Rex scopes a guy said that the Rex scopes are actually Schmidt and Bender or Swarovski brand that have minor flaws or cosmetic damage and can't be sold at a regular cost of $1600-$2200. He said that REX actually stands for Reconditioned, Extremely X-pensive
Not even in the same universe. And look nothing like either. They share about as much as a Ferrari and a
Toyota prius. No not even that much. LOL Think Yugo here!
-
Thanks Wayne

Actually that screw was tight on this one but I did use blue locktite on it. Both of the screws on the saddle (part that the stock screws into) were loose, screw on the rear of the trigger group and one of the breech screws. Those Chinese sure are in a hurry when they assemble these guns and honestly don't give a rip I'm sure.

I know that it does work great though and I'll continue using it on this gun.

I have had such bad luck with Chinese assembled equipment that I totally disassemble and inspect everything before I use it.
Especially machine shop equipment so this is necessary because of their lack of quality control.
-
Bob the Chinese guns are all like that and what you do is probably the best idea of all. I was really happy with the way this gun was shooting when I took it apart for this first time, I've also found a small crack in the stock when working on it, probably like that from the beginning. It's a minor crack in a spot where it wouldn't make a difference if it cracked more, if it does I'll spread the crack and get some wood glue in it but if it doesn't crack any further I'm not going to worry about it.
If I hadn't taken it apart there would have been problems for sure. I just got it back together and did another 32 shot chrony string and am very happy with the way it's performing now, I'll be leaving it this way because I've no doubt the shooting experience in the field will be excellent, it already was shooting very accurate before but shooting slugs the way it was I think that it'll be even better yet the way it is now.
I'll be posting the latest chrony string soon.

Here's my latest chrony/pic of the 705-9K and I'm pretty happy with the results I got from going from .110 ports to .156 and I think it will do just fine there.

Thank you for the info/photo etc, I can see the info with this color scheme......LOL
Am I correct in looking at those TP are made from alum? Do they still have a "O" ring on each side?
You may be able to use the power wheel a click or two higher,
for an average of what you had in the first string fps?
I wish my order would get here..................... :(
Thanks,
Don

Those are aluminum TP's the one on the left is the stock one that came out of the gun, the one on the right is the one that originally came out of my .25 cal and that's the one that I put in it. I had to drill out the valve exhaust port and the port in the breech to 5/32" as well. I was thinking about going bigger than 5/32" but it would have gotten into the sealing surface for the poppet on the valve. Anyway I can't wait to get out in the woods with this gun with the power that it's delivering now.

Thanks Wayne
I have got a sneaking suspicion,
that these Sentry's 702/705's would be an excellent launcher, for very HEAVY weight pills in 177 caliber?
I am thinking real HARD on a 177 rifle................... ;)
If and when my order get's here,
I'll do some careful measurements on the internals/valve etc............ ;)
as I have to replace all "O" rings and hopefully stop the air leaks, I have in both the 22 & 25 calibers.

Holy cow ordered that 702-5 this morning and it's already been shipped UPS, just check my email and I had a UPS Quantum view of it already. I did go out for a short woods walk this afternoon, I wanted to get the .22 sighted in and it wasn't far off, didn't see anything though, it's so saturated out there a person would be lucky to see any critter, at least the birds were out. I zeroed it for 40 yards and it's now dead nuts on.

I see that Mike is out of the .22 705-9K's now he's supposed to be receiving another shipment towards the end of June. I did receive my 702-5 yesterday around 11AM, all I did was open the box and take off the plastic bag on the gun and have a quick look see. I may be putting some of my 19.6 grainers over the chrony soon to see what it's doing on pwr setting #4. I did cock and shoot it without a pellet and they're definitely loud.

Mine seems to max out with the hammer spring nearing the 4.5 mark, I did go higher but hammer bounce was creeping in too much, maybe a debouncer mod on order ?

I fixed a leak in the 705-9K a few days ago, it appeared that it was leaking from the degas part, when I opened it up there was quite a bit of debris throughout the degas block (sludgy gritty stuff) encircling the o rings and a lot of it on the valve side of the block. It didn't appear that any of that stuff got down in the valve but I did a little more work on the valve while I had it apart, I burnished the valve seat with some fine steel wool. First time out after fixing the leak I did manage to get two red squirrels with it.
In the morning I got out with no luck getting a red squirrel in my sights so just before I left (way to hot by that time) I did a three shot group with it.

What gr. NOE boolet are you shooting there Wayne? seems to be very peppy from report to impact.

They're my 27.5 grain BBT's

My Xisico Sentry Deluxe has become a go to rifle recently, it's a fantastic squirrel gun with plenty of power and gives me a considerable amount of shots per fill next time I get out with it I'll try doing a 50 yard group with one of my pinup targets. The 27.5 grain BBT's that I've been casting fit it perfect and shoot really excellent from it.

Relatively older post I ran across when searching for how to de-gas my Sentry 705-9-T .25 w Mikes tune. But before getting to that I just had to say thanks for doing such a good job on this Sentry tune/mod review. It's really appreciated the way you followed through posting well laid out updates and specifics that are valuable to seasoned airgunners, and those (like myself) breaking into the PCP market with these gateway-drug priced guns.
I've found that mine shoots very well out to about 50yds and I'd consider it a great value. As I've gained extra-extra birthdays I prefer carrying a lighter rifle so I unweighted the front of my Sentry by simply removing the surprisingly heavy fore-stock. My vintage eyes also need a virtual telescope to accurately see past the end of the barrel so I gave back some weight and mounted a 6-24x50 that seems to meet my need. It'd be nice to upgrade the suppressor too but it sounds like a PIA to mod.
Unlike my .25 AV Avenger, I never did figure out how to bleed most of the pressure off of the Sentry to store it rather than simply cycle through empty rounds. Maybe I'll find an obvious answer or somebody will chime in. Also looking for a parts diagram after seeing your reference to loose screws from the mfg, and debris in the de-gassing valve.
Thanks again, Mike

Mike being that's the 705-9-T it does have a bleed screw on it but you need to take the forestock off to access it, I've got the 705-2 prototype to the 705-9 which doesn't have that bleed screw, it's basically a long tube with no openings for a bleed block or anything. In reality that gun would be a perfect nominee for a regulator because it's the biggest airtube I've seen on any of the 705's. I haven't shot that gun in about a year and it's still holding air just where I left it. It also had a different valve in it than what my 705-9 has which I was able to port to 3/16" straight into the valve without having to worry about cutting into the poppet sealing surface, that gun is capable of 65fpe with 38.5 grain BBT hollowpoints however doing that much energy I only get about 10 good shots from it so since then I backed it off considerably down to 50fpe shooting my cast 25 cal "Hunters" and now getting 24 good shots with it.
