The Roll crimp shell holder will hold all gauges of shells from 8 gauge down to 410. It can be mounted to the table of a pillar drill and held in place with the wingnut from below or it can be screwed to your loading bench with the screw supplied and used with a hand drill.
When press down with the drill to make a roll crimp the tapered hole will grip the base of the shell holding it to allow you to get a crimp.
