What rifle are you shooting? In my Lyman...my deer load is 80grs. of 2f Swiss with the 325gr. REAL bullet. Whitetails are all I've shot with it, but there's no muledeer that's gonna stand up to it either.
A good load for my rifle might be a horrible load for your rifle. Not just because they may have different barrel lengths and rates of twist, but also because each muzzleloader seems to be an individual, shooting differently than other muzzleloaders, even from the same manufacturer. Much more so than for modern cartridge guns.
What kind of gun do you have? What is its barrel length and rate of twist? That will influence whether you want to use a round ball, short conical, long conical, or even sabot (though sabots are illegal during muzzleloader season in some states). Once you have an idea of what kind of projectile you should be looking at, start experimenting until you come up with a load that's not too heavy, and shoots well and consistently.
Want a quick and inexpensive call for Moose? Take an empty 32 ounce coffee can, and make a small slit in the bottom, only about a quarter inch. Then, take one of those really big red rubber bands, the ones that go around big folders. Cut the rubber band to make one long piece.
Now, thread one end of the band and tie a knot on the outside of the can so it won't pull through. Cut the band off on the other side so it is even with the top of the can.
Now, wet your finger,...
