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.
