I would highly recommend trying Blackhorn 209 powder if you can find it.
Go ahead and Google it and read about it. Other than complaints about its cost vs. other black powers I've not seen any negative reviews. Having said that, it's still less expensive to shoot than my Weatherbys.
There is a "Modern Muzzleloader" forum as well that has a lot of info:
Modern Muzzleloader • Index page
And our own Muzzleloader forum here on LRH:
Muzzleloader Hunting - Long Range Hunting Online Magazine
The guy who goes by Encore is on both forums, and knows his stuff as do some others.
I had all 3 choices this year in NM as muzzle loader and didn't get drawn, so apparently your luck is a lot better than mine!
