Just picked up a X7 .308 Lew Horton edition with 18" threaded barrel. My wife fell in love and had to have it. Any recommended ammo to get her used to it without scaring her off? All of my .308s are either converted M1 Garands or AR-10 based. Hate to use my surplus to break in a new rifle. New to the site and Marlin bolt-actions. Own an old 336 in 30-30 (no crossbolt safety), a new 336Y for the wife and my original 1895G with ported barrel.
