While researching my first PCP, I couldn't find too many sources of information regarding the .22 S510's velocity with various pellets weights, at various settings. I figured I'd post this so someone else can dredge it up on a search.AA S510 .22 Xtra Fac fps, various pellets and power wheel settings. Rifle is factory stock, with no modifications or tuning. Numbers listed in order of power wheel increase; low (-), middle, high (+):-JSB - 13.43 gr = 550, 866, 990 - 18.1 gr = 494, 779, 899-H&N - Baracuda Match (21.3 gr) = 849 (tested high, only) - FTT Green (9.56 gr) = 619, 953, 1077I know not every gun will behave exactly the same way, but I hope this serves someone as a very general guide, or rule-of-thumb of what to expect, performance-wise.[All pellets produced a single, ragged hole at 20 yards (and that's while shooting from a wobbly metal table, on a towel, at scraps of paper grocery sacks blowing in the wind...), so not a good indicator of accuracy at range.]
I've got this exact same rifle and had it for about a year and i must say i LOVE it. The only thing i've done to it is put a Claque Air stripper on it (LDC / Moderator / (*^%) and clean it. It love AA falcons 13.43 at medium power, and JSB 15.89 @ high power really haven't shot too much 18 grains but i have some. As a matter of fact it is not that pellet fuzzy. I have shot low med and hi strings of 60, it likes to be filled at 180-190 bar shooting 40 rounds, with spreads of 50. I can EASILY shoot 1" or LESS out to 65 yards, anything within 25 yards is .5 or pellet on pellet. If I had a choice to turn back the hand and do it over again it would of been my first gun and not my 2nd. With the variable power it makes it multiple purpose back yard, inside, or long range hunting. LOVE IT, LOVE IT, LOVE IT. I will see if i can attach some stuff for ya.
I'll look at any "cons" with a super-critical eye, but only because there's way too much to like about this rifle (and because I'm a picky SOB). Because this is my first PCP, you have to take some of my observations as total noob-speak, but here goes:- Quality is amazing. I think the gun is sexy as all get-out. Nothing clanky or rattling. Everything slides and rests home with a solid feel, and no give or wiggle (lever, mag, fill). I think it's kind of weird to have a beautifully-blued tube and a matte barrel shroud, but that's just me being picky.- Accuracy is stupid. Seriously. I'd been able to understand what I'd read about LW barrels on an intellectual level, but with my first experience with the rifle, yesterday, I was able to reach that "Ohhhhh... NOW I get it..." level. It will be interesting to see what I can do at ranges exceeding 20 yards. With a real table and support. Haha.- "Lacking" is hard to address. I had originally set out to find a PCP with good power at longer ranges, multishot, good accuracy, adjustable power (long shots on ground squirrels, then jump inside a walnut dehydrator and shoot starlings), factory shroud or easily shrouded, and light weight. And I didn't want to have to go crazy modding or tuning it... I wanted performance, right out of the box. I didn't want an LDC, because I didn't want to wave around a broomstick, in the field.1. I drifted away from light weight once I didn't find rifles meeting the other criteria. I could have gone with a BSA Ultra, but I would have to mod it for power, add a shroud, and given up the variable power. Same with a Brocock. Even giving up some of my list, a Rainstorm II seemed to be hit-or-miss, for some folks (though the "hits" are really friggin' impressive). Modding a Disco to fit my list would have taken time and energy I simply didn't have (and I'm glad I realized that, since our new baby came 10 days early!). Griping about the weight is relative, though: The scoped rifle is still in the same weight range as a lot of springers, so I'm being pretty picky. It was still comfortable to carry, and a sling makes it a non-issue, really.2. Super-picky: The rifle is louder than I expected. It's absolutely NOWHERE near a naked pneumatic, but my dad's bottled QB with a TKO is a little quieter. THAT SAID... this is comparing it while it's shooting at full power. Comparing a 20fpe rifle to a 32fpe rifle is being rather nit-picky. Those vids of the Brits? 12fpe will give you a mouse-fart, for sure. Shooting the JSB RS (13gr) at medium power was a LOT more quiet (low was a silent, silent joke), and shooting the lead-free pellets on low was a joke, noise-wise. Even at full power, it's still fine to shoot in the back yard, in a neighborhood of gun-owners out in the county. I think the crack of the pellet hitting my duct seal might be louder than the rifle, though, so the backyard test is OK. I'm waiting to see how pests react to the firing cycle once I can get out to an area with a lot more ground squirrels. I may try some 15.9s on medium, to see if that's a good balance of power, shot count, and noise.3. Even more picky: Pressure on rifle in bar. Boo-hoo, right? Haha.4. Insanely picky: Fill adapter specific to the rifle. Cry me a river, I know. This is easily solved with a female BSPP/male foster adapter, so any pump with QD fittings will play nice the the s510, and any other QD fittings. D. U. N., Done.5. Weird-picky: I'd like the scope to be as close as possible to the mag, but I'd also like to try and use a small-ish sidewheel, if at all possible. Even standard 1" BKL mounts left about 1/4" of clearance from the mag, but I don't think they would allow the use of a sidewheel, based off of the short eye relief of the cheapo scope I currently have on the rifle (until my "real" scope gets here). Just something to think about.Notice how the "cons" are pretty stupid, especially the last three? So far, I'm really impressed.So, yeah: I'd definitely buy the gun, again. Even hand-pumping, I might tell past-me to save up some more and go for the twin-tube version. I was seriously looking at FX rifles, and once I'd sent off my money for the s510 and started biting my nails, wondering if I'd made the right decision, I started seeing posts about FX issues: smooth twist barrels not performing as well as expected, leak issues, etc. So, I'm totally comfortable with my choice. Haha.This is all looking at a rifle that will be entirely a hunter. If I was serious about benchrest or FT, I might choose differently. Personally--having handled and shot one at the Fresno show--I think one of Tim's custom rifles is a seriously amazing piece of hardware. If I was serious about competing in any way, shape, or form, I'd save my pennies for one of his.Other than that, this rifle seems like a keeper. I'm glad this was my first PCP, as I don't feel like getting another rifle, now. (Famous last words, right? hahaha)
As far as accuracy goes it is imho excellent my farthest kill on a ground squirrel was 146 yards with that very S510 sitting and using cross-sticks. Now I will note that I consider myself I competent shooter but nowhere near world class . So here are some groups at various yardages, all groups were shot off a plastic-fantastic MTM rest, 18 gr JSB's, and all are 5 shots:75 yardsI highly, highly recommend the SXXX series of guns to anyone considering them, I really believe them to be the absolute best in their price range, and tbh you get a *(&^ of alot of gun for the amount you pay for them. Hope this helps....cheers
Anyways I also agree with what everyone else has been saying about the rifle. When taking this out of the box this past December I felt like that kid again in that movie "a Christmas Story". What a nice smelling and shiny beautiful rifle! Being anal about all my stuff I could not find a single imperfection in the walnut wood or bluing of the metal. What great craftsmanship from our neighbors across the pond. The laser checkering gives the rifle a good grip and the trigger is smooth like butta.Accuracy wise it's pretty much mostly pellet on pellet at 25 yds. with a bench rest. I get about 32 ft./lbs. with 18gr JSB but most of in not all my shooting is done on low power since one of my shots went accidentally though mine and my neighbor's fence. I'm extremely lucky no one was hurt. I've since purchased a rimfire bullet trap with duct seal to make things extra quiet. You guys who have acreage on your private property are extremely lucky. Unfortunately I live in the suburbs and have no access to land to test my rifle past 25 yards.The only thing I would probably do is change out the fill adapter to a foster quick connect on the rifle. It is a pain in the butt getting the fill probe on and off the rifle sine it takes a lot of finessing. Not quite as smooth as it should be IMHO.
Dig: Concering your FX groups. You might want to look at your grip. Some of the groups indicated stringing 8-to-2 (sometimes strongly, sometimes slightly). I think you'll be able to shrink those, for sure.
Dig: Think of it like looking at the face of a clock. Here's a handy-dandy visual... (You cannot imagine how helpful this was, to me. I am very critical of my grouping, and watch for any of these telltale signs. Funny enough, I tend to string like you do--8-to-2--so that's why it jumped out at me in your pics... haha. With me, I find it more pronounced when I'm rushing shots, just trying to get them on paper to test what I think will be poor-performing pellets.)
