Talk:Autocannon
From Wikipedia, the free encyclopedia
From the article: "Modern tank guns (around 120 mm calibre)" I believe that caliber only refers to inch measurements. A 9mm pistol is not a 9mm caliber pistol.
- Caliber is used with metric bore measurements as well. The Jane's Infantry Weapons description of autocannon uses calibre and metric bore measurements together. W. B. Wilson 13:37, 5 May 2007 (UTC)
- http://dictionary.cambridge.org/define.asp?key=10845&dict=CALD Says nothing about inches. Just that its the diameter of the inside of a pipe -OOPSIE- 05:08, 23 October 2007 (UTC)
