Im bounceing back and forth between the 6.5X47mm Lapua, the 260 remington and the 6.5 creedmore. So i need yall to educate me on these rounds. I reload so ammo garthering abilitys is no problume. Jest give me a general education on ther pros and cons. And where can i get brass for all of them???? My goals for the rifle will be long range shooting and tactical comps. the barrle length for the rifle will be 18 inches and i also plan on hunting deer with it in colorado.
