Looking for guidance for crimping in the crimp groove of a cast bullet.
During bullet seating where do I park the bullets “sharp edge of the crimp groove” in relation to the edge of the case mouth?
Is there a rule like make the two edges evenly aligned or some number of thousands of an inch short of being evenly aligned?
A classic roll crimp or a Redding Profile crimp will be applied to finish the cartridge.
The wide flat cannelure band on jacketed bullets doesn’t give me bullet seating concerns as it easy to stop bullet insertion ¾ up the wide cannelure band, so after crimping just a thin band of cannelure knurling is still visible.
I have cast bullets from 20:1 Rotometal alloy in a SAECO #955 mold.
Sized at .452” and lubed with homemade Emmerts.
The annealed Starline 45 Colt case mouth is slightly belled to accept ~ ½ the length of the base drive band (.060”) so I can set the bullets into the cases.
I’m not using a publish load recipe, as the Starline (and others) cases new out of the bag(s) are always, always too short by one to several thou and I haven’t found a recipe that uses the SAECO #955 bullet. Therefore my load manuals published COL data is useless to me.
