Peterson .243 WIN SRP Unprimed Brass Rifle Casings


.243 Winchester remains a firm favourite for long-distance and competition shooting. And of course, the .243 Win is a good long-distance hunting round. 

Peterson's brass rifle casings are a reloader's dream – their accuracy and reliable performance is everything and more.  


Small Rifle Primer (SRP)

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. 

To make sure you don’t have any problems shooter should talk to their gunsmith and understand what their rifle is set up for before using SRP brass. 


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.
