The .318 Rimless Nitro Express Westley Richards (N.E.W.R.) is a cartridge developed by firearms manufacturer Westley Richards in the early 1900s using components from other cartridges such as .318 Belted Nitro Express and .318 Westley Richards cases. This combination offered hunter a powerful, flat shooting option in a light-weight package suitable for taking down large game animals at extended ranges.

The N.E.W.R., like its parent cartrages has rimless brass cases measuring 2 1/2 inches in length and is able to achieve velocities of up to 2,700 fps which offers excellent ballistics out to greater distances with flatter trajectories compared to other similar calibers from this era such as the .303 British or .30-06 Springfield cartridges that were more commonly used at the time.

This cartridge is rarely seen on the modern market due to its limited availability, but can still be found if you look hard enough and is available in both factory loaded ammunition as well as handloaded varieties for use in specialty firearms built specifically for this round such as those made by Dickson & Rosser and Charleville Gunmakers among others.

The Commission internationale permanente pour l'épreuve des armes à feu portatives ("Permanent International Commission for the Proof of Small Arms" – commonly abbreviated as C.I.P.) is an international organisation which sets standards for safety testing of firearms. (The word portatives ("portable") in the name refers to the fact the C.I.P. tests small arms almost exclusively; it is ordinarily omitted from the English translation of the name.) As of 2015, its members are the national governments of 14 countries, of which 11 are European Union member states. The C.I.P. safeguards that all firearms and ammunition sold to civilian purchasers in member states are safe for the users.
To achieve this, all such firearms are first proof tested at C.I.P. accredited Proof Houses. The same applies for cartridges; at regular intervals, cartridges are tested against the C.I.P. pressure specifications at the ammunition manufacturing plants and at C.I.P. accredited Proof Houses.
