I ran 6 strings of 5 shots through a chronograph with BMZ and the Lee 250 gr REAL. ES was 4 on average. That speaks very loud and supported Alliant's claim that BMZ has the lowest ES of any muzzle loading propellant. I also won 2 second places in our ML Postal matches with BMZ and my Lyman GP.
Your result and mine agree. The BMZ is definitely a match grade propellant for me.
our Lyman rifles do have an advantage in my opinion. The bore finish on Lyman rifles is superb. That helps too. My inexpensive Traditions flintlock rifle kit gun also shoots as well as my Lyman with BMZ.
I do have a CVA kit built percussion Mountain rifle with a coarse finish bore. The CVA will shoot better when more shots break it in better. I have only fired that CVA 10 times at 50 yards with BMZ. It doesn't group as well as my other rifles but has “Hunting Accuracy” The CVA just needs to be shot more to break it in. That is different from my Traditions Flint that shot fine the first time tried new with BMZ.
