Hope that covers everybody, now to the data !
Colt Military Arms Division...
The Colt SCAMP (small caliber machine pistol)was designed in the early 70's as a personal defense weapon with the equivilant lethality of a 9mm Parabellum weapon but with less recoil. Prototypes of the SCAMP fired a 2.6 gram (40 gr.).22 cal. projectile at 640 M.P.S. (2100 fps) producing a muzzle energy nearly as great as the 9mm Para.
SCAMP was managable even with it's high rate of fire. The U.S.Army subsequently experimented with similar weapons as part of the Personal Defense Weapons Program.
The magazine held 27 rds.
Semi auto & 3 rd. burst
Locked breech, fires from closed bolt
Cyclic rate of 1500 rpm
The case is a bottleneck design with length of 29 mm.
Other than the overall length being 2mm longer, the line drawing shows a case virtually identical to the 5.7 x 27 round. Base size is almost exact.
I wish I had a way to show the drawing, as it compares to a 9mm & a .22 lr
Unfortunately, I'm a computer Moron, so I don't know how to get it from the book to this page.
(Geesie, still no REAL answer, you Debbil !)
