I have a Rem700 BDL I just got off a trade/barter from my buddy. Its a clean gun 24" barrel,wood laminate stock in awsome condition. A great gun just to start. I would like to know if its something that can be done resonablly. is it easy as picking a gunsmith to convert to one of these magnum calibers? I do NOT want a 338.06 or other 06' variants please. I want a longer range caliber in the .338 range though. Is it do-able on a 30.06 action? Is it the same action basically as a 300win mag action? I have a .375 RUM that im making a larger long range boomber but don't want to alter the action to anything else. I like my RUM the way it is. THANKS!
