Started with Goex Black Powder.
Then Pyrodex (both loose and pellets),
Then 777 (both loose and pellets),
I've also shot Pioneer pellets.

Now Black Mag'3.
The most expensive (I paid $29.00 a pound). But the best in terms of performance & cleanliness in my view. I was recommended by a friend/gunsmith to switch to BM'3 after him listening to be bitch about the 777 crud ring. He gave me 1/4 pound to try out and after about 10 shots, I paid him for the 1/4 pound and immediately purchased a pound.

I shoot 120GR with a 300Grain XTP. Very hot load. Shoots very well in my Omega and this combination really lays the lumber to a deer.
They don't run very far or not at all if you shoot them correctly. I hunt a swamp bed and chasing them through the swamp is not my idea of a good time, thus I want the highest ballistics that I can muster.

I'll not shoot anything else until the next better mousetrap becomes available. Which will likely be closer to smokeless powder in terms of cleanliness.

I always opt for performance versus low price when it comes to key components. In fact, I just purchased 3 more pounds of Black Mag'3 as I'm certain that this powder is going to become a strong favorite quickly and demand will exceed supply.

Powder along with just about everything else with muzzleloading = personal preferences.
I doubt there is or ever will be a single answer to anything or for anyone.

Best,
