So if the 7 PRC uses the 375 ruger as its parent cartridge then why does RCBS list different shell holders for the two cartridges??
#4 for the 375ruger and #38 for the 7 PRC.
I have Hornady, Peterson and ADG brass. Both the number 4 and 38 fit all three. The only difference I can measure is the number 4 is about three thousandths smaller in the groove area.

My ADG brass is actually stamped Gunwerks. The #4 will not fit over the rim.
