#3270 - 6mm Creedmoor SRP Brass
6mm Creedmoor Small pocket, SR 6MM CM
1.908 - 1.912 O.A.L.
The SR 6mm CM is our small rifle primer version of the 6mm Creedmoor. Just like our SR 6.5 CM, we utilize the standard .080" flash hole diameter, as we feel this gives better ignition with slower burning and hard to ignite powders.*
The 6mm Creedmoor is the little brother to the very popular 6.5 Creedmoor. It has similar ballistics to the .243 Winchester, but its shorter length allows long, heavy bullets to be seated in the magazine. This caliber is an excellent choice for hunting, but its popularity was gained as a competition cartridge. Some of the new competitions, such as the Precision Rifle Series, require a lot of shooting and this cartridge is easy on the shoulder, even compared to the 6.5 Creedmoor. There are several companies now making bolt-action and AR-10–type rifles for this caliber.
For the Large Primer Pocket version, please see our
6mm Creedmoor cases.
*As with all types of cases this large with small primer pockets, it will require care in powder and primer selection in cooler temperatures to prevent hang fires. Single-based propellants are generally easier to ignite and a quality primer such as the Remington 7 1/2 BR are recommended.
**WARNING** In firearms that use a floating firing pin (such as the AR-15 and its variants), dropping the bolt on a chambered round could lead to a slam fire. It is important that these firearms are loaded from the magazine so that the bolt loses inertia when it strips a round from the magazine. It is also important NOT to use sensitive primers that aren't designed for use in an AR, as this increases the chance of a slam fire.

I use this in my PRS rifle and get just as good of performance as guys using brass that costs nearly twice as much!
