I currently have 22-250 in a mod 12 and want to chamber it for a 260 rem. I can grab a shaw barrel for $189 threaded for a savage. Its my first time re chambering a gun and just getting into Lr shooting so i'm new to all of this. What else would I need to do to the action to convert it to 260? I also plan on truing and bedding the action. I already have a trigger job and b/c stock
