I recently picked up a S&W 357pd in .41 mag. The expense of the ammo finally pushed me into getting into reloading.
I read ABC's of Reloading and the latest Speer manual. I am loading Berry's 210 grain with 18.5 gns. of H110 over a CCI 350 (magnum) large pistol primer. I couldn't find any reloading data for the Berry's bullet, so took -10% of the closest charge I could find, which is 20.5 grns. of H110 for a 210 grn. jacketed bullet (starting load).
So, my questions are these:
1) Was I correct in going from 20.5 grns. to 18.5 grns (10%) to componsate for the softer composition of the Berrys plated bullet (as opposed to the jacketed bullet)?
2) After sizing the cases, they fit fine in the midway .41 magnum case gauge. However, the loaded cartridges will not (after bullet seating, the cartridge diameter seems too big). Interestingly enough, those same cartridges chamber fine in the revolver cylinder. Is that normal?
Thanks!
