RCBS Universal Press Type Shell Holder #7 (30-40 Krag, 303 British)

RCBS Universal shell holders are produced from hardened steel and designed to properly align the case with the reloading die in single-stage and turret presses. They’re sized to fit specific case heads and capture 0.125 inch of the case head for proper SAAMI headspace.

And they are numbered for easy identification.
