.243 Winchester (+SRP) Brass Cartridge Cases
The .243 Winchester SRP Cartridge is manufactured on Peterson Cartridge’s new, state-of-the-art case line which uses cutting-edge technology to produce some of the most precise and consistent casings on the market. If you plan to load above SAAMI max pressure and are concerned about primer-pocket leak, this cartridge is ideal. While we do not suggest loading over SAAMI max pressures, our small primer pocket .243 Win have proven to hold up over SAAMI max pressures when tested in our universal receiver.
Lots of shooters still use .243 Winchester for long-distance and competition shooting. Rather than necking down a .308, now people can buy Peterson match-grade .243 Winchester in SRP and save the labor.
Peterson Cartridge has also observed the increase in popularity of long-distance hunting. The .243 Win is also available as an LRP.
Warning: Only use Peterson Cartridge Co. casings in firearms in good condition, designed, marked, and chambered for this cartridge. Do not use Peterson Cartridge Co casings for “fire forming” or any other purpose other than what they were designed and tested for. Peterson retains no responsibility for the enclosed casings if they are used outside of the manufacturer’s recommendations.
