I came across this new wildcat round looking up various new concoctions. The .50 Hushpuppy is made by cutting the shoulder off a 7mm wsm and sticking in a .50 bmg projectile. Initial tests with the 300gr barnes projectiles show 2,600fps delivering around 4,500ft lbs of energy. That's nearly twice as much as a .308 winchester, and double a .458 socom and .50 beowulf. And, it fits in AR platforms. You can use standard round nose projectiles or spire point. Quite interesting.
