[QUOTE="Mikecr, post: 755099, member: 1521"] But then loading to max pressures IS a choice. Right? I suggest there is no particular reason to do so, or assume so, with hunting cartridges. Lately I've reloaded for 6br, 6xc, 223, and 26wssm. I've managed well at ~55kpsi for these, except my best load for the 26wssm(IMP) is running 64Kpsi(SAAMI max for it). The load for the 26wssm: 47.4grIMR4350 @ 3020fps. 139LAP - 1.985OgvOAL, BR2, 28" barrel. This plays with any 260AI(same capacity), or 6.5x284, and would suffice for LR hunting. I mention this because it is my highest pressure load, but nowhere near where I've had it in testing(+3200fps). I'm on my second barrel with it, and some of the original ~80 cases I've prepped/culled must have 30 or 40 reloads on them by now. And given that they still exactly match my reference fireformed case, I'm certain they will last forever as they have. Now if I went with a faster load/powder(H4350), higher pressures, I could reach a node that would flat out pass most 6.5x284s. It might also shoot as well faster I don't know. But with this, I would have to FL size, and my cases would no longer be matching, and my primer pockets would open before long. Doesn't make sense to do this. Not with a milder 3020fps node at hand. Nothing about my 26wssm turned out by accident. I drew up the chamber reamer with brass/bullets in-hand, to produce desired capacity and case angles. I drew up the sizing reamer based on what I knew the cases would go to(for custom dies). I had already worked out the best load potential with QL. I went with a magnum diameter BAT action to get enough barrel steel around the chamber. And when it was all completed and tested, every number hit right on the money. I did not just neck up wssm brass and waste it in undersize actions, at ever dumber pressures(like most who've failed with this cartridge). You make good points that most of my loads are lower in pressure than SAAMI max, and that my cartridges are relatively smaller than many hunting cartridges. But it's all a matter of choices, and that's my point. If you choose a 30-06, you're choosing FL sizing. If you choose a 30SAUM, or 30WSM & set it up right, well then there are other choices about sizing, that can be made right up front. [/QUOTE]
