First to acknowledge I'm not the first down this trail, but there are a few differences germane to the endeavor. Both the .30 Reece and .30 Badger were pointed in a different ballistic direction. Both have shorter necks, and in the case of the Reece were dedicated to max performance from a velocity perspective. BTW, the Badger is based on the .38 SPCL case, not that it matters a great deal.
The .32 Miller is formed with .357 Max brass while the Miller short uses the shorter Mag brass. Nothing wrong with any of them but I had a very specific goal, that being a suppressed subsonic cast bullet shooter. I looked at an awful wide range of cartridge designs but couldn't find anything more idiot proof than a .30 cal bore and a long necked .357 case. It has met all of my objectives, though I still fiddle with load options, hence the BP adventure.
