6.5 Grendel VS 300 AAC?

[stanc]

Staff Sgt. Daniel Horner, one of the US Army’s Marksmanship Unit sharpshooters, has just won the 2011 USPSA Multigun National Championship using AAC’s 300BLK.

4 years ago, the US AMU started looking at a .308 carbine round so they could make major power factor in shooting sports competition.

The AMU first tried 300 Whisper as their entry into the major power factor.

They next looked at the 6.5 Grendel case and found they could neck it up to 7.62, giving them the round they wanted at a safe chamber pressure. In fact, the 30AS (or 30 Gremlin as it’s also known), is a solid shot out to 600 meters, has recoil similar to a 5.56, and makes major power factor in competition. It’s become the AMUs go-to round for action shooting. But, the round has an Achilles heel; magazine compatibility. The unit must make its own mags and the most 30AS ammo that will fit in a standard AR mag body is 26 rounds...

The AMU still uses the 30AS for any gun games that present more distant targets, like outlaw shooting events. But, inside 300 meters, the 300BLK is the right combination of power and compatibility to get the job done.
