Depends on how you define the word "gun". The largest ever built in terms of how wide the inside of the barrel is- would be a mortar built by the US in WW 2, known as Little David. It fired a shell that was 36 inches wide, and the shell weighed more than a ton and a half. Little David weighed 40 tons, and is located at the museum at Aberdeen Proving Grounds.

Depends what 60mm mortar you are talking about. The 60mm mortar the British Army is currently using, has a range of 3,800m (3.8 Km), or a minimum range of 180m. The 60mm mortar the US Army used in WW2, had a range of 2000m (2Km).
That is the correct US spelling of 'caliber." In the UK and some uses the variant spelling "calibre" appears.
