Does anyone have any experience with slower powders, like from AA1680 to H4895, using heavy bullets, from 200-300 grains in the 357 Max?
In particular I am looking for a start load for a 230 grain cast boolit in a T/C G2 Contender. There is AA1680 data out there from Western up to 200 grains, but nothing beyond. Would quickload work for guesstimating this?
In fact, even 357 Mag data with these super heavy for caliber bullets might be useful.
Thanks!
