Any idea of the cause and more importantly, the remedy ?
Many thanks.
I have covered this many times regarding the pellet jumping the gap from the end of the barrel to the exit hole of the pistol during recoil. Just open the exit hole very slightly to give the pellet more clear space. See link illustration of problem.
