The original Scorpions reputedly went over the limit and had to be recalled to be adjusted. As it is the Scorpion gives a hell of a thwack, and shows that BSA had 'form' in this area.
Tom Gaylord did a really interesting test some years ago and found, to his surprise, that it shot pretty well too! https://www.pyramydair.com/blog/2014...pistol-part-3/
No idea what pellets BSA used but I think they quoted velocities around 420 fps in .22 & 510 fps for 177. If & it is an if, they were 15grain 22s & 7grain 177s then that's getting close
Good deals with these members
There is provision for a longer barrel in the packaging, but what would the other compartments have contained when the gun was new ?

the scorpions ended up with pistons with a shorter stroke (the piston sear notch moved)
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
