I feel the cost complaint is very valid. It is not so much the cost of the powder but the fact for much less money, I can shoot Triple Seven or some other local powder, so no waiting for the mail man, the haz mat (which burns me for some reason) and I get the same kind of results in accuracy. Clean up never was an issue, nor was swabbing. Its part of the muzzle loader game. And when I shoot powder other them BlackHorn 209, it is cheaper to do. Any time I can save a buck it makes me happy.
What I personally get such a kick out of is how some of the people who entered the sport of muzzle loading want the rifle to act like a center fire. Shoot 200+ yards, no swabbing, no fouling, clean up is a breeze, these people would have been going crazy thirty years ago, when I was out there plugging away with a traditional rifle and round balls shooting Pyrodex RS or Black Powder.
And I am not saying one powder is better then the other. Or one philosophy of the sport is stronger then the other. If you like BlackHorn (and there is no reason you should not other then it is not sold locally) buy it, or what ever brand makes you happy and for what personal reason. If cost of product per shot is important to one person and not the other... then so be it. Also where and how I spend my sporting good dollars, for what ever reason, is my business. Do what makes you happy!!
