    I have approx. 1500 older large primers; the container's are marked as follow's:
    WESTERN NO. 7 Improved, non-mercuric, non corrosive Primers for Smokeless Powder.
    Western Cartridge Company
    Division of Olin Industries
    East Alton, Ill.
    My question is, are these primers for large pistol or large rifle? Could not find any info on the cardboard containers or elsewhere pertaining to whether pistol or rifle.
    Also, what's the real differance between pistol and rifle primers? I'm assuming that the charge is differant for each, and a rise in pressure would result,if say for instance, a large standard rifle primer was used in a pistol case.:eek:

    Pistol primers are softer and in some brands thinner material, they require less force to ignite.....rifle primers are harder and in some brands thicker, requiring more striking force to ignite. With semi-autos you want primers that are not too soft that can go off creating a slam fire.

    I am not 100% sure, but I think they are Large Pistol.
