RE: Black Mag 3
I shot a pound of it off. I liked it. Clean to shoot. Excellent power. Shot in all rifles well. Accuracy with a wide range of projectiles was excellent. Ignition was excellent. Very easy to clean up after.
Cost per pound was the real set back. I can put up with fowling and get the same accuracy at a much more cost effective price. If this powder was cheaper, it would be a much better powder to use. But to be honest, that pound of powder really went fast. I started shooting it on a monday and by late wednesday it was gone. I think that's because I was shooting more do to the lack of need for swabbing all the time.
As for how much it smokes, I never really paid attention all that much. I never condsider that a standard need for a powder. The question I ask myself always is, would I buy this powder again... NO! I will shoot Goex 3f or Triple Se7en.
