Anyone else having problems with 30 cal gas checks from Hornady?
I've been having trouble getting them to go on without shaving a little lead off the base and leaving it in the bottom lube groove.
Things I have tried:
At least 10 different boxes of checks, all new, no old stock. (I size for a commercial company)
At least 10 different 30 cal molds.
Tried expanding the checks, (helps on most but not all), using a brass round head machine screw to tap the check with a 4oz hammer.
I don't cast them, but they have varied the alloy at my request to see if that makes a difference.
