biguc, it looks fairly POTENT

but it wasn't all that great, it would have made one heck of a sniper rifle if you put a scope on it, as the recoil was very low for such a high velocity weapon.
round size: 7.9MM
Vo: 1280 M/s (4200 Feet/Second)
3 round magazine (barrell had to be changed after aprox. 300 shots)
as an anti tank gun it could penetrate 22MM at 50 Metres and 15MM at 100 Metres(60 degree armor slope).not that great unless you want to kill individual soldiers in a half track.
an interesting thing is that the barrel lenge was 120 CM (nearly 50 inches), that 's close to 2/3rds the overall lenght of the gun 176CM (about 70 inches, or nearly 6 feet)
