Thread: Loading 7.62x39 subsonic from steel cased factory ammo

Dies can handle steel cases, as a exercise I reloaded several hundred wolf steel 223 cases as a trial years ago. The wolf ammo had boxer primers so it was doable. Just neck sized with no issue although after the 3rd reloading the lacquer had worn off the necks and they flash rusted. When I went back to brass there were no wear marks or anything on the brass cases.
It doesn't sit right with me the use of bullets intended for supersonic applications at sub sonic speeds. Expansion won't occur you can of course load them back to front but my preference subsonic is a lump of cast lead can't beat it.
