I have a small box of range pick up 9mm jacketed bullets I have slowly pulled down over the years, people are always dropping bullets in the snow and rain or simply eject duds and I happily pick them up as there are always ways to recycle such things. Powder however is always disposed of as it is unsafe to try to identify and reuse such pulled down powder in such tiny lots. Just as an experiment I took a small sampling of bullets and ran them through my .357 single step swage dies pictured below are the resulting mostly formed SWC .357 bullets, all 124gr in weight. These could be loaded in .38 or .357 easily from here and sent happily down range. As with most things this novel concept is not new...it is simply not practiced often.
|9mm bullets bumped up to .357 in a single swage die, not perfect but they should fly just fine.|
