Waaaalllllll! I shoot 'nutchin' but real black powder (except for smokeless rounds). My source for black is around a 100 round trip drive, but worth the trip as there is always something else to maybe get. It's an old time gunshop where ya can sit around and 'jaw', drink java and soda's, sometimes eat some of the owners wife's brownee's, cookies, or kolochee's, swap tales and jokes, and get all the local gossip. Once in a while a real BS'er will show up and ya can get them going on tall tales and lies of his former exploits. It's not like the sterile big box stores or fancy gunshops where ya fear ya might track in a teaspoon of dirt or if ya look crosswise at shelves full of products breathing on them might disturb their arrangement. The owner as Lawrence Welk used to say has "Vonderfull, Vonderfull" prices--around $15-16 a pound for FF/FFF Goex black.
When ever he decides to call it quits, if no one continues the shop, I'll have to find a new source, if none within driving distance, I'll have to get with fellow real black powder shooters and order some from some of the online joints and split the shipping/hazemat cost. I don't like going the artificial route on anything when 'real' is available. A few things such as lubes and such, but that's it. Back in the old days, if we'd run out of Schlitz, we'd have to drink the artificial stuff. (Tis so ain't it Jubal). Shooting all the black powder subs instead of real black to me would be like mixing some water with food dye, artificial flavor, and sugar ifin ya run out of sodee's and being happy with that-that's all pop is anyway, but must be those secret formulas. JMO!!
