Air Arms S410 help

[gamerooster 1,179]

i have recently bought a secondhand aa s410, anyway today i managed to get myself a divers bottle, and once i filled the rifle up, i went out to zero it, but for some reason it would just not zero in, the majority of the time it was shooting to the left, so when i adjusted it to the right, the still went left, but the groupins where very scattered, some high, some below the target.

now the gun isent lacking power, as it was smashing through 9mm ply from 30 yards away, so my question is i guess, is that does this sound like a dodgy batch of pellets, or is the scope knackered?

There could be a number of factors at play here.

 

What pressure were you filling it to?

Going through 9mm Ply at 30 yards is going some what is the gun running at?

What pellets are you using?

And are you used to shooting a springer before getting the PCP?

i filled it to 190 bar, and i did wonder what the gun was running at, it was smashing through it, i am using airarms diablo fields, and yes the only air rifles i have had before is springers.

cheers for the help, it is much appreciated

AAF's are quite soft and exceptionally accurate in most barrels.

 

I would have the gun chronoed asap. If its running hot, they will not produce good results being a medium weight pellet.

 

The reason I asked about springers is that when I moved to PCP from Springers, I found my grouping was a bit eratic to start with and quite a few PCP converts I spoke to had the same the same.

Eventually it was put down to subconcious "Anticipation of Recoil", that is our mind and body made adjustments to compensate for the recoil and due to lack of it, we inadvertantly sent the pellet off course

The great news is that it doesn't take long top get used to the lack of recoil

the fella i bought the rifle off said he tested 6 different brands of pellets, and these where the best!!! once again, thankyou very much for the advice, top man

[Phantom 631]

Not quite sure what happened there, but my last post has vanished

 

Try again:

 

AAF's are soft pellets and are usually exceptionally accurate in most barrels

 

However... If the gun is running hot, being a medium weight pellet they will not produce good results.

 

What I and quite a few other Spring gun users have found when we moved into PCP was our groups widened up a fair bit.

It was apparently down to a "Subconcious Anticipation of Recoil" and our brains and bodies made tiny adjustments to compensate for the recoil that was not there and we were sending the pellets off course before theu left the barrel

The great news there though, is that it does not take long to re-adjust for not having to cope with the recoil.

Yep...get it chrono'd ASAP to see what it's putting out. You should be looking to achieve 11.3 ish with 16 grain AA Fields.

 

Is it indexing/loading ok? If it's tight then the pellets could be exiting the barrel deformed which would cause inaccuracy. Have a look at the brass barrel seal holder to make sure there's no damage to that. Also...if it's been tampered with then the breach and cylinder may not be aligned correctly which will cause the very slim seal between the 2 to blow through which will also cause inconsistency.

WTF is happening, first my post aint there, so I rewrite it and now both posts are up

 

Wouldn't mind if I'd been drinking but I've not (Yet)

have you tryed swapping the front and back mounts around on the scope. had this problem with my tx200. then someone on here recomended i do it as one is shorter than the other by 1 to 2mm. could be worth a shot as it sorted my tx out nicely.

i did lose the magazine on the first day i took it out, so now i am having to load it by hand, and when loading the pellets, if i struggle to get them in they were flying everywhere, but when they went in fine, they were much better

if the gun is secondhand check see if the crown has been knocked/damaged that is the usual start with a rifle but if the crown is protected then look back to the pellets

Loading manually is a way of eliminating barrel/barrel seal holder issues. When loading manually the pellet should be a snug fit....just make sure it's not deformed with the fiddling about as AA Fields have a soft skirt and can easily get bent. Once in...gently ease the bolt in and try that. If after you're groups are fine then it could be a mag issue.

 

Forgot to ask...is there a mod on it? Pellets clipping the barrel could also be the problem though having said that...the pellets generally go in the same direction when clipping.

 

I would say that you have to chrono to check power outpoint and consistency. If there are inconsistencies then it may need service/seals etc. If all's well then try manual loading to check for barrel/barrel seal holder issues. If all's well then try with the mag which will tell you if it's a mag issue. Also check the mod if it has 1 for clipping and you could try a simple proper barrel clean as that can cause the rifle to be inaccurate.

first thing. get it chrono`d, next, clean barrel, if power is ok and consistant, then enter the world of pellet testing, if you want to eliminate problems with your shooting, clamp it in a workmate and shoot 5-10 pellets into paper at about 30 yrds, if you get a good group then its you thats not doing the job, AA s400`s are usually spot on, if that does`nt cure it, go onto the AAOC and see if there is someone close to you who could give it a once over (if the AAOC is up and running, they are having problems at the moment)

[gamerooster 1,179]

right thanks for all the help fellas, but i am pretty clueless about the mechanical side of things, the gun is only just meant to of been serviced, so i cant imagine its the gun, or atleast i hope not, if its any use though, the majority of the pellets i am having a job getting into the chamber, and when i do i am having to force the bolt down, which surely cant be good for the pellets

[fry 209]

try loosening the allen screws on the figure of 8 barrel band see if the barrel srings back to centre and make sure the pellets aint clipping the silencer on the way out i.e take it off and check it isnt rattling with bits of pellets, and then try the rifle with it off. and dont make the mistake i did once trying to zero it laying down through long grass ha ha.
