The 30 mm RARDEN gun ammunition is all 30 mm RARDEN ammunition involves fixed rounds, the projectiles are crimped to the necked drawn brass cartridge cases by a crimping ring engaging in a cannelure, just above the boat tailed base on the projectile. In most cases the drive bands are sintered iron pressed into place. The rounds are issued and loaded in charger clips of three. The brass cartridge cases are 170.3 mm long and have an L16 (RO 673) percussion primer filled with 0.97 g of gunpowder G20 threaded into the
base; the rim diameter is 42.9 mm. The cartridge case is filled with variable amounts of granular NRN 141/RDN propellant. Ammunition available for the 30 mm RARDEN gun includes the following types: HE-T L13A2 The original HE-T round was the L8A1 but this was been replaced by the L13A1; the latest version is the L13A2 incorporating the RO 673 low-cost primer which was originally developed specifically for use with training ammunition. The projectile involved is machined from steel bar and contains 25.6 g of Torpex 2. An L86A2 impact fuze is threaded into the projectile nose while the shell base is occupied by an L11 tracer element which burns for a distance of over 2,000 m (time 2.6 seconds) after leaving the gun muzzle. In April 1996, it was announced that this round had been selected to be developed and manufactured as the new 30 mm Armour-Piercing Enhanced Performance (APEP) to meet British Army Staff Requirement (Land) 4053. Under the terms of an April 1996 contract, Royal Ordnance was to have supplied around 225,000 APEP rounds between the years 1998 and 2000. It was planned that a DSRR round would be developed to match the APFSDS round for training purposes. In November 1998, it was announced that the APEP contract with Royal Ordnance (now BAE Systems , RO Defence) had been cancelled as the APEP did not meet the user's specifications. The requirement for a 30 mm APEP for RARDEN guns remains outstanding. TP-T L18A2 This round replaces the earlier L12A1 and L7A4 and uses a hollow machined steel body with an aluminium fuze plug. It matches the HE-T round ballistically, having the same propelling charge, and has a tracer burning for 2.6 seconds after leaving the gun muzzle. This round incorporates the low-cost RO 673 primer.
