Also known as: MLM, Magazine Lee-Metford, Rifle Magazine Mark I, Rifle Magazine Mark II

Overview

The Lee-Metford (Magazine Lee-Metford, MLM) was the first British service rifle to combine James Paris Lee's rear-locking bolt action and detachable box magazine with the new smokeless .303 British cartridge. Adopted in 1888, the Mark I held eight rounds and the 1892 Mark II ten. Its defining feature was William Ellis Metford's shallow, rounded segmental rifling, optimised for the original black-powder .303 loading.

Notes

The Mark I's magazine was originally retained to the rifle by a chain. A magazine cut-off allowed the rifle to be fed single rounds while keeping the magazine in reserve. The rifle was quickly superseded once cordite smokeless propellant proved too erosive for Metford rifling.

Background

The smokeless cordite propellant the British rushed into the .303 cartridge burned so hot that it eroded Metford's gentle rounded rifling within a few thousand rounds. The rifle's own ammunition wore out its barrels, forcing a switch to deeper Enfield rifling and giving birth to the legendary Lee-Enfield.
