Sidepass,
If one was to truly lean on the cartridge, run pressures to maximum potential, mess with �ber slow powders (RL 33 & 50, US 869, H50BMG), I would imagine 3100-3200 would be obtainable without to much issue. I am perfectly fine and happy @~ 3000, so I have no desire to push the brass life, barrel life, recoil etc to the extreme.
Plus, I like showing people the loaded rounds (nothing super impressive about it, not much longer than my 300 wsm rounds) and seeing the looks on their faces when I say that is a .674 BC, 180 gr bullet at 3000 fps.
