Free: Contests & Raffles.
I know for a fact that my rifle is at least an MOA rifle because I did it once.
I can almost fall asleep on the rifle tried to learn all I could from my ol man. Offhand and pistol is where I shine - confidence plays a role too
Gun and shooting technique aside you will never get consistently tight groups without quality ammunition. This doesn't just mean expensive off the shelf stuff. You might get lucky with a factory load but usually the best accuracy can be achieved by loading your own.
Nice group Addicted! Most rifles take a bit of work before you find a load that shoots well.
