David doesn't quickload require the exact capacity to the base of a loaded bullet, etc? Perhaps that was another computer program?

Data for the old M95 was probably in that range of pressure.

I would think something around 2,100fps might be about max. for a DR.

The Hornady 250gr. works well on big game in that velocity range. That's what my brother used in a .356 Winchester M94 as his guiding rifle for a number of years. He dropped a number of previously wounded moose with that load - 250gr. @ 2,156fps.
