Eric, I bought a case of DB FFg & FFFg from Jon Blackert (
www.addictedtoblackpowder.com) last year and am quite pleased with its performance. (I don't like the plastic spout either.) Prior to that I used Goex and Graf's (Wano) and have found DB to be at least as good as those brands, maybe better. However, I've not chorongraphed any of them, so I can't give you mean velocities, standard deviations, and extreme spreads. Accuracy is unchanged though and the bbl's. foul about the same as with Goex and Graf's, and, of course, the price was right.
