    CCI 400 are small rifle Primers

    CCI 450 are small rifle magnum primers

    Use 400 in the 223. I don't remember ever using a small rifle magnum primer and can't come up with a reason to use it. I suppose there is a magnum load using a small rifle primer????? But I sure can't come up with what it would be.

    Check the load data some powders call for a mag primer in 223, Speer # 13 loading manual calls for a mag primer when using powders like 748 and H335 reguardless of charge weight.
