On the Starline website, it says 475 Linebaugh, large rifle primer. Now, I've used the Hornady brass and it calls for a large Pistol Magnum primer. Anyway, what are your thoughts on large rifle primers for this cartridge?

Second question: Is the 475 L Starline brass faithful to the original specs (rim diameter) or is it in line with the newer specs for FA revolvers and such?
