The inert 18-pounder shrapnel round was a crucial munition for the British QF (Quick Firing) 18-pounder field gun, extensively used during World War I. Designed primarily to counter infantry and soft targets, this round featured a cylindrical shell packed with hundreds of lead or steel balls, propelled by a timed fuse. Upon reaching a pre-set point in its trajectory, the fuse ignited a small bursting charge, scattering the shrapnel balls over a wide area, effectively creating a deadly hail of projectiles.

The round itself was approximately 83mm in diameter, weighing 18 pounds (8.16 kg), with a brass or steel driving band for stabilization and rifling engagement. The casing was typically made of steel, with markings indicating its inert status, meaning it contained no explosives and was safe for handling and training purposes.

The 18-pounder gun, with its shrapnel round, became the backbone of British artillery during the Great War, delivering devastating barrages against enemy positions. The inert version of this round, devoid of explosive components, serves as a historical artifact, offering insight into the technological advancements and strategic importance of artillery in early 20th-century warfare
