Description

.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.

History

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.

Additional Information

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.


Many competitive shooters prefer Small Rifle Primer pockets (SRP) because they experience longer primer pocket life due to the increased material in the head of the case. There is also a belief that Small Rifle Primers produce a more consistent ignition. Some people even report better groupings and lower velocity spreads.

However, SRP are not recommended for shooting in extreme cold or hot temperatures. And Small Rifle Primer Brass sometimes requires the firing pin on your gun to be bushed. This depends on your rifle and your bolt. If that is not done, you risk getting pierced primers. For more information on bushing your firing please watch this YouTube video https://www.youtube.com/watch?v=-CDJKLp7BsI.

To make sure you don’t have any problems talk to your gunsmith and understand what your rifle is set up for before using SRP brass. Doing that will make sure your reloading and shooting experience is much more enjoyable.
