I was crunching some numbers on trail boss, and found it to be extremely cost effective. I think that will be my next powder (I have many manuals to reference, BTW, but a little less money to buy the damned components). I also found this pretty interesting view on the youtube about TB. Who knew the old timer black powder methods could be adapted to modern powder???

Thank you all for the suggestions. I think I've got some loading to do...
