I have an ARC Nucleus in 300 prc and would like to go with something like a 6.5 PRC for smaller game. I understand the bolt heads and obviously the barrel swap but what about magazines. I have an MRAD and a DTA and those have special magazines for the shorter cartridges in the long action. Is there something like that for AICS? Thanks
