I’m looking at getting back into long range shooting and have decided on the 300wm for those uses. The only drawback that I can find for this caliber for my purposes is the decreased barrel life compared to a 6.5 Creedmoor. I have thought about getting a separate rifle with 308/6.5 to be able to shoot/practice more. But that comes along with the cost of gun, scope, reloading supplies. Let say I do burn through a barrel in 12-1500 rounds. What is the process and the cost of putting a new barrel on it to keep within the same caliber?
