I have a savage 111 topped with decent glass and would like to get another barrel to make it a switch barrel rifle. I'd like to get a 30" 338 Edge barrel + Muscle Brake. What all does it entail to have the barrel threaded and muzzle brake "timed"? I'm probably going to have a smith do the work, would just like to know if I'll have to send the action in or not. Also, how hard is it to swap the bolt head and is there some initial fitting involved or is it a drop-in part? How long would you say it would take to swap a barrel and bolt head from one configuration to the next? Would I be better off using a separate bolt and swapping bolt and barrel? Thanks for any help!
