Morning all,
Looking for some advice, 177 HW100k with A&M cylinder.
I haven't used it for a while, tried it yesterday and the POI at 25 yards had dropped about 3 mil dots.
Removed cylinder which vented any air left in it, put cylinder back on, refilled and appears to be back to normal.
Is it a cylinder issue or the reg in the gun sticking?
Cheers all
