Ok here's the setup: .50 caliber 100 gr. pyrodex pellets 295 gr. powerbelt bullets. Shot two perfect bullseyes then tried a third shot and hit 6-7 inches straight left. What is going on? Could my scope have been bumped or what? I try to use the same amount of pressure with the ram rod every time. Could that be a problem also? Could I have just jerked before the shot or what? Thanks for the info.
