I had a new paper Federal Premium 2 3/4 dram 1 1/8 oz that didn't fire. Just for my own curiousity,I grabbed my Unloader, and cut it open. To my surprise, the powder was mostly black flakes interspersed with green flakes. It weighed 18.5 grains. I have heard that they don't use the same powder that we do but it sure looked the same as the green dot that I have. Probably a different burning rate.
