Aas400 accuracy gone

[robhw97k]

Alright lads,i bought my aas400 brand new from shop,straight out the box with rws superdomes the accuracy was silly good,then after 6 minths or so i did a pull through,since ive done this it hasnt been same gun,the accuracy is crap,its all over the place since pull through its had 200 ish pellets through it yet its still crap.any ideas why? Id love to get it on a table over 30 yards but theres knowhere round here i can do that,if anyone got advice or somone near me can try it that be big help.thanks

O-ring for probe dislodged?

It could be a lot of things, but if it happened just after a pull-through I'd check that the breech seal is still in place and undamaged. I'd also check it out with Air Arms pellets.

Good luck

I might send gun to tony wall of sandwell field sports cos i fancy regulator fitted,going to cost few quid all in all but i love this rifle n want it sorted.

What did you use for the pull through?
Archer50 is likely right about the breach seal.

Barrel clamp? It could be loose or misaligned?

[robhw97k]

Right lads av just spoke to tony wall n he says sounds like ive pulled out o ring when i did pull through,ive no idea what this o ring looks like but ive just looked breach and its brass cant see no o ring its just brass looking,i can send pics by email if somone wants av a look.cheers

Good shout, Only one problem I ever had with an AA rifle and the above had worked a little loose,
