anyone know how to go about tuning the AA S510?
I think mine is not making the best use of it’s air, and is showing high Es and Sd numbers. I generally like to tune such rifles to give a flat shot string, which is reflective of low Es and corresponding low Sd values. But this is the first rifle I’ve owned with a power adjustment so I’m not sure how that figures into effective tuning, except that maybe I do all my tuning with the power set to max, then maybe benefit from it after I tune the rifle to where I want it. Any help will be appreciated.
than kyou,

I’ve owned three AA S series pcps.
I’ve found in .22, at FAC levels, there’s not much that can be done to improve anything. Regulators don’t really work well on them and there is little to no shot count improvement unless you are willing to go WAY down in FPE.
I’ve not found one honest regulator supplier that recommends their product on the AA S4XX/5XX rifles or carbines.
However, in 12 FPE versions, a regulator makes a lot of sense and will show some serious improvements overall.
In short, these are English built pcp’s, and were likely designed for 12 FPE, and at that power there are changes that can be made to improve their performance. However, in .22 caliber and .25 caliber, they are simply maxed out on performance and not much can be done to help.
As said before, these are a $995 out of the box shooter, with a very nice tirgger, excellent accuracy, ten shot magazine, and beautiful stock. Modders need not apply! You’ll just frustrate yourselves.
However, at 30 FPE, 30 shots at high power, with excellent accuracy, what’s to complain about? For a pcp with a tube air cylinder, that’s just about as much as you should expect out of a sub $1000 USD pcp rifle.
Put a bullpup stock on it and it is a fine little setup for the money.

PS: Don’t even think about a .25 caliber. All you get is a larger bore barrel with the standard .117 and .22 valve and air supply. Performance is as expected with this setup.
Thanks for the advice. I’ve got more offers coming in. A Daystate Harrier and a BSA Scorpion T10 Black Tactical. I’ve checked both on the Yellow, and the owners want to trade even. It’s OK to ask, I suppose. 🙄

I don’t know much about them, I think 80 grit had one, I would do a search on the Yellow forum for a BSA Sportsman, you should get many pages of the good bad and ugly on it.
The FX Timberwolf is a sweet rifle I hear, I always liked the lines of them and have been tempted on the grade 3 stocked ones.

RC, someone has offered me BSA Sportsman in trade. He want’s a few dollars as well, but it has a custom stock which looks fantastic. I’m not familiar with this rifle so I’m doing my homework, but do you have any knowledge of this rifle? I know the Gamo DynaMax is a clone, but…
darryl
Ps it’s a .22 multi-shot. It seems the owner went to the trouble of putting that custom stock on it for some reason, but I don’t think that was to make it a better shooting rifle, so maybe this one is a decent one? Also, I’ve dealt with him before. I got my FX Timberwolf from him, and that rifle exceeded my expectations, age aside.
Daryyl,
I see you posted that problem child for sale on the Yellow, wise move.
My first high end airgun was a AAS410 carbine SL with the classic tube.
It had been crudely skelentonized, which I redid and the gun was a thing of beauty, until you lifted it and found that it was way too heavy for what it was.
And I found it to be exceptionally accurate without wandering issues like other brands on this forum :wink:, but no accurate than my two much lighter Royales, the difference was that I could go much farther afield with the Royales than I could with my AAS410 or my Condor and not have to return for a drink of air.
May you sell it quickly and move on to a much more effecient rifle.

I wrongly guessed you had a .22. For the .177, I’d try the JSBs. The barrels like them a lot. The .177 go up to 13.4 gr. I’d guess the Exact at 8.4 gr., if your at a lower power setting, or the Exact heavy at 10.2 gr.
Again, make sure the barrel is clean and a chrony will help get your power level vs. pellet figured.
Before you decide to sell/trade it, I’d advise you give those pellets a try. For squirrels, the s510s are plenty good. Shot one yesterday at 40 yds., instant drop.
If you get a regulator installed and tell the gunsmith you want it to shoot the 8.4 gr. JSBs, I bet you’d get a higher shot count with lower deviations. With the heavies, the count will be lower, but who knows on the accuracy?
My gun performed poorly with ‘cudas, compared to JSB.
So I think those 16.1 grains would be a bit too much for my shooting needs. but, I did ask. I should have been more specific. I target shoot and plink a lot. Sometimes I’ll take a pest, but nothing larger than a squirrel, and only those if I see them ripping through my potted plants on my deck. Neighbors want me to knock them out of their gardens too. I guess I’m good where I am. The rifle easily makes 15 FPE with the barracudas, and set on about 40% power.

16.1 g eun jin.
Man, than you for the insight to this rifle. You and the others here give me pause when I contemplate selling it. I know the rifle performs better with heavier pellets. I wonder what the heaviest pellet is for a .177 like mine? I’ll pop over the PA’s site to see what’s available. I see what you mean by the crude air system, and small air supply. it helps to explain the larger Es in the 3rd shot string. Apparently the air pressure depletes pretty fast by that string. I see it in several of my spreadsheets. the one way to life that string is to soften the hammer strike. I think I can do that wit a softer spring. But I need to study this rifle before taking it down. Gotta do my homework. in the interest of greater consistency over the shot strings, I am willing to sacrifice maximum power for maximum efficiency. Well, some power is good. I “settled” for 28 FPE on my Logun S16 🙂
Guys, some advice, please. What would be a good replacement for this rifle? I’d like something in a multi-shot carbine (already had an S200). Can’t afford a Daystate Huntsman XL. Of course I’d like for it to be power-adjustable. It’s OK if it’s not a carbine. Accuracy and light weight are important too. I like to older FX series like the Timberwolf i own (great rifle). Falcon FN 12? Decent shot count~30 good shots per fill?
So maybe I keep this rifle, and maybe I sell or trade it.
thank you guys,

Darryl,
If you’re running a S510 Xtra FAC, you might do well w/ JSB 15.9 gr. at full power; that’s what I find best. I’m getting dime and under sized groups @ 45 yds (front braced/hand held), so the differences in fps over 18-20 shots can’t be too bad. So far, I’ve had worse results with lighter pellets. Some, like Premiers are acceptable at 45 yds. (3/4 in. groups), but there are a lot more flyers.
The S510s seem to dislike dirty barrels more than most guns. Dave may be right and a look into the mechanisms is warranted. But, I’d try the JSBs and clean the barrel if you’ve been shooting a lot of pellets, especially different types.
The air use system is fairly crude, and the air cylinder is a bit small, but for hunting, these are great guns. They’re light, easy to fill w/ a Hill pump, safe to transport with a magazine (1st pellet chamber put in empty). I’ve killed a pile of squirrels up to 65 yds (as far as I’ve tried) and a couple large groundhogs, many rabbits. A few days back, I was practicing by shooting the bases of tulip-tree flowers @ 50 yds ., no problem. It was fun watching the flowers explode.
For me, the biggest troublemaker has been the indexing post/spring. If that sucker isn’t turning the magazine to a audible “click” and the mag. chambers are not precisely aligned, you can get very small dents in the skirts as the rod pushes pellets in. I’m replacing mine, since it has some age and a bunch of manual adjustments have fatigued the spring. It’s a $9. + change part and a few hex bolts for an easy fix.
Good luck!
the flatter shot strings are at reduced power, using heavier pellets (10.34 and 10.65)

modders need not apply. well in a nation of tinkerers that’s a hard reality pill to swallow, but your words ring true. So, BSA Scorpion T10 Black Tactical with a Hawke Panorama 3-12×40 and Kasten shroud? 😀
