Peterson Cartridge .243 Winchester Brass (brand part no. 40006-R) is unprimed rifle brass built with a Small Rifle Primer (SRP) pocket, giving handloaders an option most other brass makers don’t offer for this cartridge. Peterson Cartridge manufactures the brass in the USA on its precision case line, and the small primer pocket design has proven to hold up over SAAMI max pressures in Peterson’s own universal receiver testing. Long-range and competition shooters who prefer the more consistent ignition of a small rifle primer have few other sources for .243 Win brass built this way. Among reloading brass, this Peterson brass favors precision handloaders who want SRP-pocket .243 Win brass for consistent, repeatable loads.
