Thanks for another great tip Max
10 small puffs of air out = approx 30FPS reduction.
I've got it about right now, but a bit of a compromise, because Superdomes (14.4gr) go a full 1.5 FPE less than Premiers (14.3gr). (The rifle is .22 cal. btw).
I guess this is possibly due to the Superdomes being a tighter fit to 'thumb' in to the breech.
Felt recoil and cocking effort have certainly increased from the 8.4FPE it was running at.
I've now fitted a Dampa mount (from JSR) and my trusty Leupold M8, plus I've adjusted the trigger, so next some accuracy testing
(Amazing how much can get done with the BBS being off-line!).
I hope the Premiers are best, as they'll prolly be an inch less drop at 50 yards (from a 30 yard zero) than the S'domes.
Thanks again for the helpful replies, gang
