rwjshooter,

     There are a bunch of us here in the VA/Carolinas area (and our "family" on up into Ohio, even  ) who are shooting the Charlie Dell-made version of that cartridge concept.  In all cases it is based on the .357 case or its equivalent necked down to a true .32 caliber.  Everyone I know of shoots it breech seated with bullet weights around 200 gr. +/- 10 gr or so.  One favorite powder lately has been Hodgden's surplus H-108, but unfortunately the last know supply of that has been sold as of this writing.   

     My personal "formula" is a 200 gr Barnett S-7 bullet cast at 25-1 pure lead and tin and seated about 1/16" in front of the case.  I am using Starline .357 brass necked down with a push die and arbor press, Federal Small Rifle Match primers and about 11.6 gr. of the H-108 with a 3/16 cork wad seated about 0.01" off the powder to contain it.  I shoot this in a bench gun with Peregrine action and Douglas barrel with very happy results.  YMMV, of course.

HTH, the Frog
