Weren't there some Scandinavian 20mm shoulder fired rifles?

That would be .787 caliber weapon. A .950 caliber would be the equivalent of 24 mm. Either one is what used to be called a "cannon" when mounted on a fighter aircraft.

Yes, see my post 17.

You would think the pedants around here believe cooks can't convert from English measurements to metric.

My point was the 20mm didn't work well as a shoulderfired, and the .950 should suck about 4.x mm more.
