RCBS® 5-Station Shell Plates properly align the case with the reloading die during reloading. They're built from hardened steel and capture 0.125-inch of the case head for proper SAAMI headspacing. They feature five stations and are for use on PiggyBack™, PiggyBack II, PiggyBack—3, PiggyBack—4, AmmoMaster® Auto, Pro 2000® and Pro 2000 Auto progressive presses.
