The big thing about Blackhorn is no swabbing, and its very consistent, both in grain and velocity spreads. If your already coming from a Muzzleloader background (traditional) then you are used to swabbing, Blackhorn is Non Hydroscopic (does not wick moisture) They all have pros and cons. (the swabbing regimen is focused on a different principle for different powders, but the method, and end result are standard across the board) The more accurate claim you always hear is kind of open to interpretation, and I dont feel is truly substantiated. Some guys like it, some dont. I shoot it in my guns that can, But I also shoot real black, and several subs in some that cant really shoot BH reliably, or safely. Its not the end all be all powder, It is good, but most are good, and each has its set of merits and followers. Goex is a fine powder, and if it keeps you happy, you can shoot the same powder you use in flintlock in any inline.
