The 300grn Lehigh is a proven bullet on big game with a 45/70 CF Rifle. The current Muzzleloader bullets have not been tested on any Moose or Elk size game. If i wanted to stop a Moose in it's tracks, the 275grn Lehigh would be my first choice with a around 130grns of BH209. If i was not concerned about a little tracking i would go for the 300grn Barnes original or the 275grn Parker BE.
