Everything I've read suggest using standard rifle primers so that's why the CCI 200 were used. The 30.4 grains is not maximum mid level. I finally found a pound of AA 1680 and want to reload first chance I get. The only published data I have found for the 445 SM is Hornady and Seirra and I prefer the Hornady data with the XTP bullets.
