A smooth bore of less than 2” calibre with a barrel at least 24” long is a shotgun and can be placed on a SGC. Anything else is a firearm.

I'll have a mooch and see what I can find out.
My concern is how the PTB view a firearm with a barrel of around 2" that has no 'stock'. Most mini-cannon I've seen are at least 6" long barrel-wise, and Section 1. A SGC would cover multiple shotguns of the type covered by the Shtogun Certificate, but NOT a Section 1 shotgun like this. One Section 1 shotgun = 1 entry on a FAC.
