IWS 2000 is wery formidable weapon. It fires 20 gramm (308 grains) tungsten dart (fleschette) with muzzle velocity of 1450 meters per second (4750 fps). At 1000 meters this projectile will penetrate a 40 mm of RHA (rollded homogenous steel armour) and will result in serious secondary fragmentation effect behind the armour. That said, it will penetrate two walls of any modern APC at one kilometer range. The trajectory is very flat and does not rise higher than 800 mm above the line of sight when fired to 1000 meters. The cartridge is of somewhat original design, and has plastic case with steel head and base. The projectile is concealed within a plastic sabot.

Yes, and it's quite impressive indeed but at 15.2mm it's not going to be civilian-legal under BATF so for most folks the 'puny'
.50 BMG Barrett is the best they can do.
