Check this out. I have one, but haven't hunted with it yet. No cleaning, no smoke, and vastly longer range with little drop. Visualize 30-06 performance with 250 to 300 grains of .458 bullet in a .50 sabot. Savage also sells one, but it's more money and I don't like it as well.

And if you put smokeless powder in your muzzleloader, plan a funeral before you try it the first (and last) time . . . CB
whats not to like about the savage?
