Thinking about putting another rifle togather, and I am wanting to try either a .260, or 6.5 Creedmoor. I assume since the .260 is based from the .308 it'll feed just fine from unmodded magazines, but what about the 6.5 Creedmoor? I'd hate to get everything, and bolt it in a chassis, only to find out that there are feeding issues, to be dealt with.
