air arms s410 wont group

[harry18]

Well after reviving my lovely looking s410 from chrisboy today i went about zeroing it in, It has a btas regulator fitted and recently had the magazine parts replaced. I was shooting at 15meters and the pellets spread over the size on abit of a4 paper. I tried it with the silencer on and off and tried loosening the barrel band i even tried manually loading the pellets but all with no luck and it's seems very extreme. Does anyone have any ideas? chrisboy has been very helpful and it willing to cover the costs to fix the problem.
Thanks
Harry

theres loads of reason why the rifle could be shooting the way it is, as white said, get it over a chrono first.

As said hes took silencer off ......more than likely regs goosed 410,s shoot usually bang on and bombproof had about 20 of them
Now in deals
Id say regs the likely suspect hence the chrono check

Hi Harry did you fill it with a pump or bottle could need a good blast of air to reset reg

[harry18]

Hi everyone, i filled using a pump and am going to my local gun shop tomorrow to get it cronoed, How would i tell if the reg is buggered? The shots are not just high or low they are all over the place, the pellet does seem to need a push to get it into the barrel.

The readings from the chrono will be all over to

The barrel and indexing probe could be out of centre?

The barrel and indexing probe could be out of centre?

would that be a easy fix?

[AlexHW100]

its pretty rare it would be, but try a new mag and if the pellets are still stiff to index then i would take it to a gunsmith as the mis-alignment would be hard to fix if you dont know what you are doing and could end up costing a lot of money

The AA S410 is one of the simplest guns to work on, you can get a complete breakdown
on the web, and I`m sure S410 owners would keep you right.
The Reg is most likely the problem.
Pellets? I`ve always used AA field in S410`s best stick to these.
Never heard of probe alignment probs on these guns, but barrel could be out by a few hundredths
of a mill.
It could be a simple breech seal that needs replaced?
Finally Scope! these have been known to fail, and can loose zero constantly so it might not be the gun?
best of luck!

You could also try the air arms owners club, google should throw up a link.

If its not a reg issue I would check the hammer rail , here's one that was covered in 'dried grease ' which caused a lot of accuracy problems >>> HAMMER RAIL <<<
