Looks like DarrenC is the winner!

Changed to AccuPels & instantly back to tight groupings. RWS seem to have bollocked up their previously brilliant Superfields and replaced them with crap!

Thanks to everyone for their help & good advice, especially DarrenC!

Moved to a new tin of RWS recently, and could expect POi to change but still get a grouping. No grouping whatsoever now. Tried 3 different tins of RWS & all same. Previous 6 tins of RWS have been spot on. Indoor range so not wind affecting flight. Be back on Wednesday to try £5 test and bolts/sc...

Will do the simples & report back later in week (travelling till Thursday).

Pellets were RWS Superfields which to date have been brilliant.

Many thanks for your help!

Hi Guys I was at the range yesterday happily knocking down targets at 50 yards, but suddenly the gun lost all accuracy! Nothing significant had happened to the rifle - Mid refill - Same pellets - Not dropped or knocked I kinda get 2-3 pellets grouped, then one 3" wide right, then 2" wide l...

Yup, barrel is same with lathed end. I think you may well be right! New barrel?

Okay, mate has admitted to dropping rifle off the boot of his car! Still strange that gun & mod seem fine independently, but can't get on together...

Hi Guys My mate has a S400 that recently got fitted with an AA Q-Tec moderator. All seemed fine, but when I used it the other day, pellets were getting flung high left. Took mod off the gun & sights back on the money. Put the mod on my S410 & it shoots straight. Back to the S400 & pellet...

Hi Everyone

Does anyone happen to have a spare o-ring (part number S650)?

My S410 Carbine Superlite seems to be missing this part on the bolt probe & without it, the bolt keeps opening on it's own.

If anyone could help out i'd much appreciate it!

Cheers
James

Okay, so word back from the gun shop is that it was indeed missing the breach o ring. Also it was suggested to lubricate the mag o rings with silicone every 250 pellets. Now apparently working as the AA Gods intended!!! Many thanks to DarrenC & Blackbaronfish, cheers fellas! Also thanks to Granv...
