Some thoughts please lads

Hi guys

Some techy guidance please…

My R3m in .25 flavour is bothering me in the accuracy department. I’ve gone through all 80+ pages of the edgun forum and searched thoroughly of some possible causes (some I’ve yet to try so bare with me).

Speed 940fps
JSB Kings & Air Arms Fields tried and tested.
Atlas Bipod
S&B PM2 scope
Custom baffled cover with 2.5″ extension (have done tests with factory baffle cover)
Barrel cleaned and polished & re-leaded

I can’t seem to get a good solid consistent accuracy from her. From the factory she was doing 955fps and I gained a sub 1″ group at 100yds with Air Arms Field pellets from the magazine on a single attempt. I didn’t secure the HST upon receipt so naturally it backed off and when chrono’d was doing 870ish fps.

Reset and secured the HST at 950fps and am struggling.

I’ve not yet tried a different scope, setting a lower fps than 940 (as yet).

Chrono string was good when I set the speed to 940fps with a 5fps spread over 2 mags.

I tested her tonight and tried single feeding (between gnats biting the sh&t outta me!!) and got a nice tight group at 35yds. Have checked the baffles and no signs of clipping. Tried loose grip, firm grip, loading bipod, gentle reward pull on bipod, no bipod etc.

Always seem to get a flier with every group I try.

Here’s some pics for reference…(coin in pic is british 5p 18mm across)

35yd 3 shot Zero group after barrel polished with baffle extension shroud cover (speed 950fps) Air Arms Field Pellets

35yd Test groups (speed 940fps) JSB King

40yd Test group (speed 940fps) JSB King

100yd Test Group (speed 940 fps) JSB King

Any thoughts and ideas before I start playing with speeds & different scope??

Cheers
