Have annealed many different types of pistol cases when forming or when special loading. Example, when I load the 200 RCBS for a 357 Mag revolver or my Marlin 94c, the bullet is seated then taper crimped over the ojive, after the case mouth is expanded in the brass/brass cases with a highly compressed load of H-110 / 296 w SRPs. The annealing saves on the number of split necks from work hardening. I use the old water in a pan and torch in the dark method.
