    They say Standard or Magnum loads. that isn't clear to me, which charge to use for say, .357 mag or .44 mag? i don't understand how they are interchangeable. can someone explain?

    In most applications, with most brands of primers, Magnum primers are only necessary with ball powders.

    Stick & flake type powders do not benefit from Magnum primers, and in some cases will present pressure & standard deviation (velocity differances between shots) problems that wouldn't be problems with standard primers.

    Winchester is different, in that their WPL Lg pistol & WSR Small rifle primer is usable with either type powder.

    "357 mag take small pistol primers 44 mag take large pistol primers "

    jesus no wonder they didn't fit! no really...to clarify:

    "Winchester is different, in that their WPL Lg pistol & WSR Small rifle primer is usable with either type powder."

    so for the record, the Winchester Large Pistol Primers for Standard or Magnum loads can be used as a magnum primer with H110 mag loads AND as a standard primer with 2400 loads?

    Its just hard for me to understand since I have always separated std and mag primers for these two powders.

    The Win LP Primers seem pretty hot. I've not used them for any H110 loads, but they give very low sd's in .45acp w/ HS6.

    Winchester WLP will easily and reliably ignite 296/H110 in .44 Magnum loads. They also work just fine with 231 in .45 ACP.

    However, if you're looking at 296 in a .357 Magnum and you want to use a Winchester primer, you should go with the WSPM, the small pistol magnum. Regular WSP fail to ignite 296 about 20% of the time.
