I bought a pound of Hodgens CFE 223 powder to try out. The Hodgen/IMR/Winchester load data site lists loads for this powder but doesn't list what primer to use. I'm starting with 27.0grs of CFE 223 powder, Rem cases, and a 50gr Nosler Sptz bullet. I don't know if I should use a mag or standard primer. Anyone know what type of primer I should use? I have CCI SR Mag primers, Fed SR match primers, and Win SR primers. Thanks.
