Simply - - -> Being a somewhat faster .308" the 300Win Mag,with a 1:10 twist will shoot anything great. From the 220 down to a 110. Go fer it.
For the sake of "full disclosure " . . . I do not now,nor have I ever, owned a 300Win Mag. But I did not have to Google it. I'm just one smart son of a bitch. --- SAWMAN
