The cartridge is the new 257 Firecat. In the pic below, the 6.5 Creedmore is on the left, the new 257 Firecat on the right. The Firecat holds almost 10 grains more powder and works flawlessly in an AR-10 platform. We haven't done the final chrono work on it yet but by early testing it should give us 150 fps more than the 6.5 Creedmore.
