    Hypothetical question. For a given load using CCI LP 300 primers, and for that same give load using a CCI 350 LP magnum primer, what is the difference in the pressure from the LP to the Mag. Will this create a unsafe condition? I am loading with Clays 45acp LSCW 200gr using 3.6 gr. Suggested staring load. Thanks all for your help Chuckie Schumer and all the other bed wetters needs to have a link to this site.

    I don't think anyone except a laboratory with pressure measuring equipment could answer your first question. Regarding your second question, if you are using the starting load, you may substitute Magnum primers for standard primers without causing pressure problems.
