[QUOTE="Mikecr, post: 2029084, member: 1521"] IMR4350, full case but not packed or compressed. My mid-load is 47.4gr, providing 3020fps/8ES at 65Kpsi, 140VLDs, 28" barrel. I can push it to a higher node with H4350, but it's not quite as accurate, and requires FL sizing. This is my fitted chamber in 26wssm Imp, which matches 260AI H20 capacity. It's a BAT magnum action, coned breech. If you loosely follow this path, while cutting any corner, you'll fail to reach me. You'll pressure out early, and/or be forced to accept shorter/unstable brass life. There are 1kyd BR shooters who have tried 260AI, and 26wssm, and they didn't do well. But when you look closer at the whys of it, it's pretty obvious these cartridges did not fail them. Instead, they failed the cartridges. The sum of their planning often amounted to no more than excess -clearances/annealing/sizing/hope. [/QUOTE]
