Already put my axis in a better stock that is puller and glass bedded, also put a new trigger in it. I want to change calibers to shoot long range on the cheap and swap calibers. I have a savage lrp 6.5 creedmoor so I want something able to shoot beyond 1300 yards.
Questions:
1. can I change out the bolt face to a .532 and rebarrel to a 7mm saum or 28 Nosler?

2. If not what caliber would you choose with the .308 bolt face? Was thinking 6.5 prc or 280 ack. Imp.
