hi, I have just brought a Hatsan AT44-10 Tactical rifle new & I have cleaned the barrel to make sure it is not full of oil.
but I am finding that every now & then when I shoot it some of the pellets are going from anything from 1mil dot to 4 mil dots out at 30 yards.
I am using jsb 452 .177 pellets with a Hawke Panorama EV 4-12x40 AO IR/EV 1/2 mil dot scope which is fine.
has anyone got any clues as to what it could be that is causing this. thanks
