Template:Infobox Firearm Cartridge The .242 Rimless Nitro Express, also known as the .242 Vickers and initially called the .242 Manton, was a rimless bottleneck centerfire rifle cartridge developed by Kynoch for J. Manton & Co of Calcutta and introduced in 1923.[1][2]

The .242 Rimless is very similar to the .243 Winchester in performance, although the cartridge is significantly longer. It fired a 100 gr projectile at 2800 fps.[1][2]
