H&G 68 clone is choice #1. Lyman 452460 is close behind. Size to .452, lube with NRA 50-50.
Use a fast powder like Bullseye or Titegroup. Seat H&G 68 clone to 1.250-1.260 based on your
chamber (use dismounted barrel as gage) and taper crimp as a separate operation to .465 to .470
diam at front of case mouth.
