I do have to agree that supplies are limited for this caliber but the ballistics are pretty impressive. With a 150 grains of powder and a 375 grain bullet(Knight Red Hot), muzzle velocity is 1938 feet per second with 3127 ft/lbs of energy. A friend at camp a few weeks ago had just purchase a Knight Revolution-2 and shot a doe with it. I was very impressed with the termial performance. The exit wound was massive.
