They don't tell the ballistics of their round, but the cartridge is not necked-down very much. I bet the muzzle velocity is less than 2000 fps.

Muzzle velocity is 2100 ft per sec and they say so in the video.

This is not a whole lot different than shooting a one ounce (437.5 grain) 12-gauge slug from a rifled barrel.

The 12 gauge comes nowhere near the 25,000 ft-lbs of muzzle energy.

You can buy 12 gauge slugs in the 8,000 ft-lbs range. They are very painful to shoot out of a pump shot gun. I hope they have a decent recoil management system! I see an ER visit after lighting off one of these rounds.

Bump for later viewing.
