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.

**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.
