Maine Rifle,

Basically what everyone else said: That load will work fine.

In fact I'd happily hunt black bear (or most other North American big game) with the equivalent of the original black powder loadings. Have seen a big bull bison go down within 30 yards after being shot through both lungs with a black powder load--and the bullet exited.
