Peterson Cartridge 7mm PRC Large Rifle Primer Brass 50ct

Fifty count box of Peterson 7mm PRC brass, set up for a large rifle primer.

Primer pocket size is worth confirming before any brass purchase, and this box is the large rifle primer version, so your primers and your priming tool need to match it. Buying fifty at a time keeps a batch together, which is how most handloaders track case life: one lot, one load record, one count of firings. On a magnum case that kind of batch discipline is the difference between knowing where your brass is in its life and guessing.
