Is it feasible to rethroat "sporting"rifles from 223Rem and 308Win to
5.56x45 NATO and 7.62x51 NATO respectively?,is it cost effective?
I like to use military surplus[boxer,non corrosive] ammo for plinking and varmints.The ammo is cheaper and the varmints don't appreciate being hit with whatever one uses.
My rifles:bolt,pump,lever,break open:are chambered in:223Rem and 308Win.
Yes,I know I'll void any factory warranties[that also applies to any handloads,so it's a "non-issue"].
Can it be done?,possible cost?,who does it?
Thanks.
