Depends on the brass. Originally it was large rifle by Remington. Silver State Armory made theirs with small rifle primers which is supposed to give some ability to gain a little edge in velocity. Now Silver State makes both while, AFAIK Remington only makes them for large rifle primers. Not sure about Hornady. Edited - actually I just remembered that I picked up two boxes of Hornady V-MAX at a gun show to compare with my handloads. Just looked at one of them and they have small primers.
I've only used Remington brass, so all of mine are large rifle primers.
