Hey y'all. Hows everyone doing? So i've got a question for some of you gunsmiths or guys who have experience in changing calibers of guns. so i have a Remington 700 xcr in a .270 win. with a 24 inch standard barrel issued by the Remington company. A few friends and I want to get into shooting .308 win. and we were wondering if it is possible to change my rifle into a .308 with a heavy barrel (including the action and magazine and that stuff). if so would it be cheaper to just buy a new Remington sps tactical in .308 win.? ANY AND ALL RECOMMENDATIONS ARE WELCOME! thanks!
