Peterson Cartridge Match-Grade brass rifle casings.
NOTE: All their SRP casings feature a small flash hole in the diameter of 0.060” vs. the 0.080” flash hole found in their LRP casings. This means you will need an X-small/ Undersized Decapping Pin to deprime their casings.
WARNING: Lead - Discharging firearms in poorly ventilated areas, cleaning firearms, or handling ammunition may result in exposure to lead and other substances known to cause birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation at all times. Wash hands thoroughly after exposure.
