WARNING: Never load less than the minimum charges shown in the loading data as the small charge of propellant may not be sufficient to push the bullet completely down the barrel. <br />Although 50 Action Express bullets are the correct diameter, they are too lightly constructed for use in the 500 S&W Magnum even with reduced loads. In addition, they have no crimp cannelure to hold them in place. <br />The 500 S&W Magnum cartridge case was designed for LARGE RIFLE PRIMERS such as the CCI no. 250 and Federal 215Magnum. Do not use Large Pistol primers.
