Just as the title says. Preferably something that’s not burnt out but would like something with a few hundred rounds/broken in. Something along the lines of a 7mm-08, 6.5 creed, 260, 308
My brother has a 6.5 CM 24" SS CTR and is considering rebarreling to a 6CM... I'll let him know you're looking for a barrel. His rifle shoots very well with factory ammo. Probably only 200-300 rounds down the barrel.
