Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. ... a weapon go from being a machine gun to a cannon? I mean you have a walloping big .50 cal machine gun, then a 20mm cannon etc... Hoping some gun nuts can square this away. :?
  2. calibre depending.
  3. Small Arms Ammunition is considered less than 20mm. Therefore less than 20mm is fired from a machine gun.

    20mm and more is a shell and fired from a cannon.
  4. Is there a machine gun in current use of a greater calibre than the DSHKA?
  5. I don't think so, but ugly will know best.
  6. Cheers mate, may put an argu... discussion to rest.
  7. There was a 15mm Besa tank MG, developed in the UK during WW2. It wasn't a success.
