If we can trust the (absolutely massive) mass above, this round exits the barrel with Just over 8,000 foot-lbs. I doubt this would be effective against modern tank armor, but it certainly will work against even heavy armor on all other vehicles including apcs.Ĭompare this to a 5 mm/35 SMc - a 39 grain round at 4,250 fps yielding about 1,564 foot-lbs on impact.

The sabot was fired out of a smoothbore barrel with the dart achieving 4500 feet/sec velocity. The projectile consisted of a saboted depleted uranium dart weighing 11.9 gram ( 183.6 grains ).
