Sounds like experiences vary. Suspect chamber pressures, barrel lengths and bullets make a difference.

I would be curious to know the chamber pressure, regardless of powder, to get a 250 grain bullet to 2700 FPS with a 35 Whelen or 2800 fps in a 358 NM case. North of 70K psi I suspect.

Physics of volume:pressure and potential:kinetic energy conversions are stubborn things.
