It is called black powder and you can mail order the firearms that utilize it.
Here is an alternative. Use a revolver and a rifle that take the same round. 357, 44 mag etc. Lee sells a small hand loading tool that works very well with the pistol rounds. Carry bullets, primers, powder and reuse the brass. This was done in the wild west as ammunition was expensive.

"As democracy is perfected, the office of President represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be occupied by a downright fool and complete narcissistic moron."
