Peterson Cartridge 7mm PRC Large Rifle Primer Brass

The Peterson Cartridge 7mm PRC Large Rifle Primer Brass (brand part no. 40073-R) is new, unprimed 7mm PRC brass machined to tight dimensional tolerances, sold 50 cases to a box for handloaders building their own ammunition from scratch. Consistent case-to-case dimensions out of the box mean more uniform neck tension and case capacity across a full batch of handloads, without a break-in firing needed first.

Frequently Asked Questions

Is this brass primed? No, this brass is unprimed; primers are sold separately and seated by the handloader as part of the loading process.

Does this brass need to be resized before first use? New unfired brass generally does not require full-length resizing before first loading, though a light neck size is common practice among precision reloaders.
