LOL I quit buying the stuff a long time ago and make my own as RR suggested. Dang stuff is expensive. BUT you can NOT transport the stuff once the 2 elements are mixed together. You grind the 2 elements to a fairly fine powder, store them separately, transport them separately and mix them at the site you are shooting. I like the stuff myself for long range practice. When I'm not "banging the gong" it's a definite signal that you hit the mark without all the walking. And it's pretty funny when you sneak a 1 pounder behind the target and the wife didn't know it :D
