    Some place I saw where primers were rated from athe hottest to the mildest.
    Does anyone know where or do you have that information?
    thanks

    Actually, there really is no foolproof "List" on how "Hot" primers are. They will vary with different loads and combinations. If you are trying to substitute primers according to a "list", you could be in for trouble. It's best to use reliable data and common sense when substituting components. The pressures can vary greatly and there is no consistent "HOT" list. The hottest primer in one load may end up being the mildest in another. It's a crap shoot at best. Start with mild pressure loads and work accordingly. If the loads are listed over 9500 PSI, I'd be real careful.

    Here's a couple of articles by Tom Armbrust that might help illustrate the issue. Lyman had some similar info in their loading manual. They strongly recommend against primer substitutions.
