I have an old Savage model 12FLV in 223rem I want to re barrel it to 6.5 Creedmoor, can this be done first off? my plan is to build a custom rifle off this action and make a long-range shooter out of it, is it wort it, or should I just start off with a 6.5CR rifle? I plan to have the action blue printed and add all the good stuff like a good barrel Chassie system stock good trigger {ETC} your thoughts!
