Hi folks im shooting a savage 12 f/tr in 308 calibre out to 1000 yards using the new sierra palma bullet over varget powder, the rifle is shooting really well but im thinking about the day the barrel starts to turn downhill and what is the best option for a barrel change. I would wish to continue with the 155 grain bullet and would like to hear your opinions or experiences with aftermarket barrels for savage 12 f/trs..thanks.
