Auto Prime shell holders

The Lee Auto Prime uses unique shell holders made specifically for it.  The numbers on them correspond with those on the Universal Shell holders that are made for use in presses.  However, they differ in the sense that the Auto Prime shell holders do not have a bottom lug that is present on the Universal holders.  This was not done to sell more shell holders, it was done to prevent the tool from having to pass a primer through the additional distance of the lug.  This would have resulted in a less accurate tool and one that would have required a much greater distance for the lever to travel to seat a primer.

While some people purchase the proper Auto Prime shell holder when they load a different caliber, we do offer a set that contains the holders that fit over 115 calibers.
