I picked up a Savage 340 bolt action rifle chambered in 30-30 and have had a couple of people tell me that I should get it chambered to the Ackley Improved. I talked to a gunsmith today and he told me that it would cost about $150 for him to do it. Does this sound right? Why would it be so expensive? Isnt it just a matter of reaming out the chamber a bit? I am not doubting what he told me, but rather just kind of taken back a bit when I read that it was just a simple job. Is it even worth having done?
