Weatherby did some testing years ago firing a 308 projectile around 60 grains out of a 30-378 that I seem to recall was well over 5000 FPS.

Although the XTPs are really intended for pistols so the jackets are pretty thin. So not sure what would come out the end of your 30-284 barrel

Yea I am well short of that case capacity and dont really have the faster powders selection but might have a play next time at the range.
