I'm a relative newcomer to the muzzle loader.
Using a TC Encore with a Williams peep sight. I experimented with loads and seemed to get consistent results with Powerbelts using 100 grains Pyrodex. I like the accuracy.

A stupid mistake cost me an elk last year.
I used one of those Eberlestock gunrunner packs with the built in (muzzle down) scabbard. Great pack. Up high I got into elk and primed the gun. I foolishly forgot to re-tamp the load. One of the herd gave me a broadside look through the trees. The charge did a slow burn. No boom or cloud of smoke. The Powerbelt exited and arc'd into the dirt after a couple dozen yards.
