You sure? The Gatling design is mechanical in much the same as a lever action is.

Semi auto, or Self Loading in UK parlance, uses some the power of the discharged cartridge to operate the mechanism.

That said, why .22lr? As it's not a self loader, you could build it in full bore..! I do remember reading about a 2/3rds scale model of a Gatling, made as a hobby and chambered for Brocock cartridges. But then, that's gone as well!

However, I think you would not be able to do it. I reckon it would be classed as S.5, by the virtues of S5(1)(a)....... machine gun.

Sec 5(1)(ac) any self-loading or pump-action smooth-bore gun which is not an air weapon or chambered for .22 rim-fire cartridges and either has a barrel less than 24" in length or is less than 40" in length overall e.g. self loading shotguns;
