If you want small groups, reload, it's your best tool for tweeking a rifle for accuracy!
The next thing is a solid bench, concrete is preferable!
Ever herd of follow thru? If you don't you'll never shoot your best. Start with an empty rifle, prefrebly with a snap cap although I usually just leave an empty case in the chamber. Take careful aim and practice squeezing off a shot and try to not let the cross hairs move off target.
This is great practice for trigger control as well as breath control. It will also help brake the habbit of brakeing your form as you anticipate the trigger break, it also helps to pass time while your barrel cools.
Never allow your rifle to beat
you up, use a recoil shild of some sort and limit your live fire sessions!
And yes I have a few that will do better than moa, thay have one thing in common (Savage) Glenn
