Crimp die sticking a bit
Quote from Reloader on June 18, 2013, 10:14 amLoading .45 ACP's on my 650 I had a problem this last round with the cases sticking a bit as they came out of the crimp die. Little flakes of brass can be seen on the shell plate.
New R-P cases with Sierra 185 JHP. Fit the case gage perfeckt. Fired 40 test loads. Perfeckt.
Any ideas?
Thanks,
Robert

The carbon inside a fired case acts as a dry lubricant to prevent the case from sticking on the expander. With new brass, use steel wool or a scotchbrite pad to wipe off the end of the expander every 25-35 cycles to prevent galled brass from building up on the funnel.
Dry tumbling using corncob or walnut media will not remove this carbon coating, unlike wet ultrasonic cleaning does.
With new brass we recommend tumbling for a few minutes to remove the small brass flakes that are left during the impact extrusion process
