The South African Denel-Mechem NTW-20 is a 20mm anti-material rifle and arguably the world’s most powerful sniper rifle. Its 20mm cartridge is 50% larger than the .50 caliber and has an effective range of over 3,000 yards.

The NTW-20 is a South African anti-materiel rifle or large-calibre sniper rifle, developed by Denel’s Mechem division in the 1990s. The weapon was designed by Tony Neophytou and intended for deployment against a wide variety of targets, including parked aircraft, telecommunication masts, power lines, missile sites, radar installations, refineries, satellite dishes, gun emplacements, bunkers and personnel, using a range of specialized projectiles. The NTW-20 in 20 x 110 calibre is a new version of the weapon. The accurate high explosive capability makes it extremely effective in the counter-sniping role, where indiscriminate fire from weapons such as mortars and rocket launchers is completely unacceptable. The new NTW 20 are now offered in 20 x 110 mm Hispano calibre. This calibre is highly efficient in terms of velocity, penetration and target effect.
