If you could have 1 and only 1 fully custom rifle. What caliber would it be? Here in the next year or so, I am going to start collecting parts for my first full blown custom rifle. I currently own a Rem .308, Savage 22-250 Ackley and a Savage .284 win that are all semi custom. This rifle will be used a a general purpose rifle. Ranges out to 1200, mostly steel targets, more than likely it will not be a comp gun just be used on my private range for fun.
