I am really liking the results I'm getting from the Black MZ. It burns as clean as BH209, you don't need a special breech plug and you get higher velocities at lower pressures.
Got a link to actual pressure traces with velocity or are you just repeating the manufacture's claim?
Higher velocity than what?...Pyrodex?....well that really isnt saying much. Swiss or Olde Eynsford will spank Pyrodex all day long too
