Hi, Blueridge:
I've never loaded it, but I believe you can neck up .30 Remington brass. Huntington's have it.

My catalogues are a couple of years old, but RCBS, Redding and CH/4D list dies. Lyman #46 data suggests backing off a couple of grains from .32 Special data. For a 170 gr. Flat Point bullet in the .32 Remington.
Powder MAX Velocity
4198 26.0 1992
3031 30.0 2020
4064 32.0 1980
4895 33.0 2070
4320 35.0 2136 compressed
RX7 31.0 2252 accurate (Alliant Reloder 7)
Lyman warns that some bores are as tight as .319" and loads should be worked up very carefully. Hopefully someone who has one can verify this.
Bye
Jack
