I use Unique in 12 gauge loads, 9 mm, 38 special, 45 auto. It's taking me a while but I am getting my 8#er down to the last couple of pounds. It takes a while at 4.6g loads in the 9 mm's.

Are there cleaner burning powders, probably. But Unique can sure be used in a wide variety of loads.

Laws aren't preventative measures. In other words, more laws won't prevent gun crime from happening.
