BESA Machine Gun 15mm (Machine Gun)
Developed by BSA from the Czechoslovak ZB vz.60 heavy machine gun which used 15mm ammunition.
This 15mm gun was used in the armoured divisions as their supply lines were separated from the infantry who used .303 bullets. Once the British started capturing German ammunition this could be immediately used in these tank machine guns.
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.
