I have a Savage 110 in 300 Win Mag. with a sporter barrel. Best grouping I can get is .915" with my reloads, shoots .915"-985" consistently. It won't shoot factory ammo to save its life. Which is not a big deal now that I reload. Would I beneficial to change to a match grade barrel? Or would I be better off spending money else wear? Any advice is welcome. I am new to the long range shooting. Have been an avid shooter all my life.
