The South African Denel-Mechem NTW-20 is a beautiful weapon and is currently the world’s most powerful sniper rifle.  Being careful in a choice of words, the NTW-20 is a 20 mm manually operated, rotating bolt action, anti-materiel rifle.  The design of the NTW-20 supports both 20 mm and 50 cal configurations.  An operator can switch between the two calibers in the field without using any special tools.

The NTW-20 is a serious weapon.  The 20 mm version has a maximum effective range that is greater than 1500 meters and the 50 caliber version is quoted at 2300+ meters.  A single shot version chambered for the 20 x 110 mm Hispano-Suisa cartrige packs a muzzle energy of 32,000 ft lbs (~44,000 J) which is quite a whollop when compared to a 44 magnum with its a muzzle energy of about 1200 ft lbs.

The 20 mm ammuniton choices include high explosive, fragmentation and incendiery rounds.  Interestingly, when armor piercing ability is required the muniton of choice is the 50 cal round.

I love this weapon.  This second video is more a tribute to its good looks and great capabilities.  Enjoy.
