For any of you who are out of smokeless powder. Miss Kitty Kat and I stopped by Frost Cutlery (right off I-75 in Ooltewah). We found a limited supply of the following smokeless powder at the retail knife store. Most of these look like shot shell powders, but you could check if they have any possible application for metallic cartridges.
1. Accurate Nitro 100 NF
2. Winchester AA Super-Handicap
3. Alliant E3
