    Anyone know of a primer hardness chart or graph??

    Just curious as to the different hardness of primers. I know federal tend to be the softest and desirable among revolver shooters with aftermarket spring kits. I also know that M1A guys prefer a harder primer to prevent slam fires in their rifles and Springfield even recommends only shooting ammo loaded with milspec primers, such as CCI-34 in their rifles.

    Careful man, there's a beverage here!
