RE: sulfur smell??
Some like the smell and heavy smoke. If you do not; there are substitute powders that do not have as much smoke and most do not have the sulfur smell. Tripple Seven is the most likely one you will find, after that you might find American Pioneer, Or Goex Pinnacle, the absolutely best substitute I like is Black Mag'3 which is very hard to find and usually has to be ordered factory direct. It has very little smoke and almost no smell. It also has very little fouling in the barrel after shooting. Just a light gray powder.
