90 grains of BM3 with a 330 grain bullet.

90gr. Black Mag'3 with 300gr. SST shot completely through elk chest (no major bone hit). Similar results with same powder charge and 295gr. aero tip Powerbelt. Both of these shots were at about 90 to 100 yards at 7000ft. elevation.

Forgot to mention the above was with a .50 stainless Omega. Using .25ACP conversion with Winchester small rifle primer.

40 grn with a .490 patched round ball out of a Hawken.
