The S510 just landed. This gun is un. believable. (OK, honeymooning a bit)

Jeremy, Have you tried the Air Arms or JSB 18.13 pellets? For me in my .22 FX, the AA's were the best grouping and the JSB next. If you intend to hunt with the S510 I can tell you that the diablo pellet leaves nothing behind compared with the "Hunting" style pellets. I have taken a raccoon at 65 yards with a head shot and it was DRT. Squirrels with head shots at 45yards are a breeze.The diablo's were the most efficient in the gun at all power levels.

As you know I just bought that KPB .25 and I tried the H&N Grizzly pellet in it. Crap! TI was over at Jimmy's ( Camp Fussell,) and those things were all over the place at only 24 yards. No better then 2" CTC...! . They are a hollow point pellet and very short. they could almost turn sideways in the mag. I reviewed them on PA and told them they should remove them from inventory, and I was not alone in the sentiment based on the other reviews.... 

I didn't know if you had the feeling that the hunting pellets were better for your use or not. If you have not tried the the AA"s or JSB, you might be surprised on how they perform for you.

Remember my recommendations come with a disclaimer: Just because it works for me, It may not have the same results for you.
...In that case just tell me to shut up! HAHAHA 

Congrats on the new rifle Really sweet one there...

Well, in my experience, domed diabolo pellets are fine for brain shots, and the definitely keep their energy better downrange. Usually group tighter too. But they're not very efficient at dumping their energy when they hit the animal. It just doesn't take that much energy to scramble an animals brain. Where it makes a big difference is in hits to the heart/lung area. Expanding hunting ammo really causes a lot more damage in there, and causes them to drown faster. A shot that might just nudge the heart with a dome would cut a chunk out of it with an expanded hollow point, for example. I've had more than one case now where I saw where my pellet hit the squirrel, and it seemed too low and far forward, but sure enough it brain-damaged him. With domes on that kind of shot, they run off and starve.

The challenge is getting ammo that will expand, but still be accurate and reasonably efficient flying through the air at longer distances. H&N Baracuda Hunter and Predator Polymags are the only ones I've found so far. Polymags are generally not as good at high velocities as the H&N Baracuda Hunters, and the Baracuda Hunters are not QUITE as accurate as the preferred domes for my guns, which is usually the suitable weight Air Arms pellets.

Of course, with .22 caliber, placement is not QUITE as critical as with .177. Even domes do a lot more damage than .177 domes. For example, I noticed that chest shots bleed a lot more from .22 than .177. 

I need to order up some Air Arms domes in .22 in my next PA order. They always shoot just a bit better than JSBs for me.

Edit: forgot to answer your question. Yes, I tried JSB domes in 14.3, 15.9 and 18.1 gr. 15.9 and 18.1 gave the same accuracy at 35 yards. (you can see in the targets I posted above; I labeled which pellets were used)

Jeremy, forget the questions above. i looked at your post while fixing dinner with the wife in one ear. 

I see your point. I only take head shots or not at all. I experienced the same with body shots and diablos. I am a serious hunter \( powder burners) for just about anything that moves and I can eat. I have shot squirrels with .22 long lead bullets in the chest and they crawl off and dig in under bushes , never to be found.

So I bought a .17 HMR and ballistic tip Hornady bullets. they shred the squirrel no matter where you hit them. Too much meat loss. The FX at 32 FPE and the JSBs really did the trick. I have hit some in the body by mistake when the critter moved as I tripped the sear. They do the same crawling off. 

Fortunately around my hunting property I have coyotes and gray foxes that think I am feeding them..lol I'm serious... I have filmed foxes coming out of the bushes after a run off squirrel with it in its mouth... I am usually in my deer ground blind.

ddransomi: I don't know why they stopped making that model.

Smug: i love my s510 and will never sell it best looking gun in my collection. You should have your son take a couple of shots and you got down range 25 yards or so you will get a better idea of the sound. I do recommend power setting of 3 for best results it still should yield 22FPE with 16 jsbs if shooting with other homes in close proximity. I have and LDC on my rifle Lead Dust Collectors we do not put silencers on airguns. My 510 is FAC US specs fully shrouded. I got the LDC from Neil Claque and he has post some information on the laws in the US on LDC. Air rifles are not guns and so the silencers rule i believe is a little gray. I believe some places require them to be semi permanent installed (glued).

Jeremy: I too will agree, i only take head shots and if that means reducing the distance then I do so. I also only shoot using domed pellets because they are the most accurate. I have been tempted to use hunting rounds but they just don't shot as well over 25 yards. So if you are shooting 30 yards and less shot hunting rounds, but anything more i would recommend 16 or 18 grain JSB's. This group is at 75 yards and on high power not 3. I found that my gun shoots the BEST on high power at all ranges, but it is not back yard friendly in high power.



I didn't see your link with your grouping, but i know when i shoot @ 25 yards its not pellet on pellet but its always within .5-1 inch. I have noticed when i shoot further that group size holds true at 50-75 yards 1-1.5 inches, and at 100 yards 1.5 to 3 inches

I shot it at the 30 yard indoor range yesterday, and it's still one ragged hole. The P-Rod, by comparison, was more like 1.75" avg. and not nearly as consistent. To be fair, that's a new gun, not broken in yet, and at 1/3 the cost, I guess I shouldn't expect miracles. But I was hoping for 1" average or better. It was also shot from the bench, instead of field target position, but still shot much bigger.

The Compatto is on par with the S510. Not one ragged hole, but it is a smaller caliber, so that's much harder to do, and it also just has a 12X scope vs the 32x that the S510 had.

my s510 .22 cal will do 3 mm ctc at 28.5 yards, all guns are diddferent...im sure your gun can shoot smaller groups than the ones you posted.
​did u clean your barrel? and or try differnt pellets. I think mabe u have yet to find the guns magic pellet it likes?

​with aa 16 grain all shots pass through the same hole smaller than a .177 calibre pellet with.. this is at 28 yards..out doors
I will never sell my s510..its the most accurate air rifle I have ever had.

Just ordered an adapter and TKO muzzle brake for the S510. Talked to Mike @ TKO for awhile on the phone; he's quite knowledgeable and he's going to try to taper the back of the brake up from the 20mm shroud diameter up to the 1" brake diameter.

I put a highly-regarded UTG 4-14x44 AO tactical scope on it. It's nowhere near as nice as the Meuller. The sight picture is bright enough, but at 14X, it is VERY sensitive to eye position. (blacks out easily) As always, mil dots are nice. Built-in hood and lit reticle is nice too. I need to sell a few scopes and upgrade this one to a mid-range scope in the $400-500 range, I think, in order to get a lit mil dot reticle and at least 14X zoom with clear optics that aren't too position-sensitive.

Thinking about ordering up a Marmot Militia barrel for the P-Rod, to try to get proper accuracy out of it, but I don't think it'll ever shoot like the S510. It's a $150 barrel for a $200 gun, but I like the handling of the gun so much, I'm really tempted. Got a brake on the way for it as well; it has quite a bark for a shrouded gun...

The tuned, reg'd walnut Kral PB should be coming in a week or so. I have high hopes for that too, but I'm not sure if it'll ever keep pace with the S510 either.

I think I've found a real keeper in this S510. Only downside is just a normal shot count, and in this age of reg'd PCPs, will it satisfy for ever? Probably not, if I get a tank, but while I'm hand-pumping, it doesn't matter. :)

FWIW, I had both, a Prod with a MMHF barrel/Huma regulator and a AAS510 carbine. In my case, with the Prod tuned to shoot JSB's 18.1 at 700 fps and the S510 shooting JSB's 18.1 at 865 fps, I can say that both guns were equally accurate up to 40 yards, but the S510 was easier to shoot accurately. Past 40 yards and, up to about 60 yards, the S510 was more accurate hands down.
