Follow through. Being so important to accurately shooting an air rifle, it gets ingrained into you and becomes second nature. It directly impacted my scores in both High Power and Palma rifle shooting on the positive side.
TooJung2Die (BTW great name and avatar) - - - I noticed that I tend to use a light artillery hold on rimfires and low/no recoiling rifles such as a .223. So, that's likely helped a lot with my springer shooting. But ya better hold on to the Big Boys or you're likely to get a serious case of 'scope eye' and a scar as a reminder. - - (Don't ask me how I know about that. I'll just say that 3 1/2" mag turkey loads from a 7 1/2 lb shotgun - equal to the recoil of a 378 Weatherby & more recoil than the typical 458 mag rifle - are 'brisk' )
