I did not see any estimations of pressure or load data, I would look at moderate loads out of a 444 , not a handgun, that is why I asked here. I have read of the 380 cases in 38/55's here, that is why I asked. I Measured some fired , unsized cases and they were a perfect match for my jacketed bulk Remingtons, +- 001. I can see where a swaging operation would make them very usable and negate the need for a mold, just pour and shoot, maybe even just load with shot and swage. The more data available before I start experimenting the better.
