I bought some Black MZ from Sportsmans Warehouse a few years back. It was
an excellent deal but now used up. I think that it would sell if re-introduced.
The residue is less but more baked on stuff. There always seems to be a trade off.
The cleanest powder to me is Swiss 3f caviar ball. That is Gold. You have top power
and easy clean up-- and it is true to tradition. Plus real black can be stored for future.
Big trade-off there is price. I have not chrono ed the Swiss but I think it out performs
many of these synthetic substitutes.
Black Powder will be plentiful. It is not the risk of reduced supply or of excessive demand.
The risk is regulatory. In places, it is restricted by law to small amounts or prohibited.
This could be extended or made nationwide. Will this happen? Who knows? But many
do not want to be caught off guard if it does. A rumor can affect the markets a year ahead.
I think it is reasonable to have a year's use of Black powder put aside. Those who put aside
more , are not considering the risks of the future legality of excessive quantities in private
hands. Wisdom is moderation in all things.
