I have an opportunity to purchase a heavy 308 barrel for my 30-06 110 (long action). I have been unable to determine what sort of box magazine I'll need to make this work. Savage used to only make the long action, and chambered them in the usual long action & std length magnums, but with the advent of the model 10 length action, the old short calibers in a long action went the way of the dinosaurs. Does anybody know if I'll need a special magazine box & follower to make this project feed from the mag box?
