So I was casually googling "What is the fastest firing gun" And uhm Apparently The M61 Vulcan *Ahem* The A1 Version is 6k rpm but then the A2 version is 6.6k rpm Getting ready for WWIII Maybe even WWIV who knows XD
Also it's rounds tho (I mean it's a frickin Vulcan Cannon but still these are fat lol) -- https://cdn.shopify.com/s/files/1/0859/1360/products/20mm-vulcan-collectors-cannon-roundcannon-roundlucky-shot-usalucky-shot-usa-17066600_2000x.jpg?v=1551886112
