I am deer hunting now with my 54 cal black powder muzzleloader. Too bad I can't seem to get out much this year but it is more than enough caliber for white tail. Mine likes 90 grains of 3F Goex.

I do intend to get out as well with my blunderbuss and a 4 bore round ball, but need to get a little more practice time in before I would hunt with it. During hunting season it is a major event to opt for practice with a new shooter INSTEAD of getting in the woods to hunt.
