I have a Remington 700 in 223 that I had trued and put a .250 precision ground recoil lug and a shouldered hawk hill heavy Palma 7 twist barrel installed on. My question is can I buy a bolt with a 308 bolt face and lap it to the reciever, then buy a remage prefit barrel in whatever cartridge and swap back and forth between the shouldered barrel and the remage prefit?
