Britain Lewis Gun

Showing the details of the shells used(where known)   Tweet Weapon Details Lewis Gun (Machine Gun) History The lewis gun was designed by an American Colonel Isaac Lewis in 1911. The Birmingham Small Arms Company purchased a licence to manufacture the Lewis machine gun in England, which made Lewis very wealthy. Lewis and his factory moved to England before 1914, away from possible seizure in the event of a German invasion as it was originally based in Belgium. The Lewis gun used a horizontal pan magazine which held either 47 or 97 0.303 rounds. The gun was used by a large number of Countries during World War II, and in most Theatres of the War.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
