[QUOTE="Mikecr, post: 1354494, member: 1521"] I could put together a system that would get infinite case life from a 6.5x47. My accurate mid-node from 6.5wssm Imp(260AI capacity), 28" barrel, is 3025fps/140gr with only 47.4gr IMR 4350. My [U]accurate[/U] barrel life(two barrels so far) is consistently 1850 rounds. That's 650 more than a 6.5x284. I don't FL size, or neck size, or anneal, or trim, no problems, and my cases will last [B]forever[/B]. By QL this is right at SAAMI max, 65Kpsi, and it's very accurate at mid node(most common competitive) & 16.5lb form. Testing for 'MyMax', the point of needing body sizing, took me over 3200fps. But this doesn't just happen. It takes a plan. I'm confident a 260AI would perform just the same -with a plan. The excessive 6.5x284, with greater area, and more and slower powder does nothing better. These are just opinions of mine. No way to prove best. But it doesn't hurt to slow down and consider this stuff. Pick your bullet, pick your capacity. [/QUOTE]
