The .338 Lapua Magnum came out of military long-range sniping and now anchors a lot of ELR and PRS-style long-range rifles, with some hunters taking it after large game at distance. At those distances, case consistency matters, and Peterson says its equipment produces casings that are structurally consistent. Peterson describes its brass as American-made and match-grade, and it publishes how it’s made. C260 cartridge brass goes through three draw presses, with annealing and washing between draws. Carbide cutters, replaced frequently, are Peterson’s answer to mouth burrs. Peterson says its flash holes are uniform casing to casing and that it anneals by induction rather than flame. Peterson also says every casing is inspected, by both automated and hand methods.
This lot is Peterson-made .338 Lapua Magnum with a BWA headstamp. It’s new production and unprimed, and we’ve prepped it in 50-count lots for the handloader.
