I have been using Hornady 158 gr xtp bullets and 14.5 grs of 2400 w/cci 500 small pistol primers in new starline 357 brass Great load for me. shot 400 of them so far. Ordered 1,000 zero 158 great JHP bullets the other day because I was sick of paying Hornady prices. Anyway went to the local store yesterday and they only had Federal 200 small pistol Magnum primers. It's like 50/50 out there on the web saying you don't need Magnum primers. I get it, 2400 works fine with standard primers. What are your guys thoughts on the Magnum primers with 2400? same load but with Magnum primers.
