In 1903 Karl Puff (German)  proposed the
idea
of a Taper bore weapon, an ingenious
innovation in which the barrel of the
weapon squeezed the projectile, converting
the
short fat projectiles into longer, narrower
projectiles with a better aerodynamic shape
before they left the muzzle
.
In the early 1970's Colt experimented with
the idea of squeezing a sabot with 3
projectiles  to creat a Triplex Salvo. They
used the sabot in
the Colt model 1971 Auto Pistol with a
special tapered bore.
The 3 projectiles would leave the barrel of
the pistol at different velocities and make 3
different holes in the target, which was the
idea behind the Salvo program - more holes
more damage.
Colt also  worked with Israel on the
9mm for a taper-bore version of the Uzi
SMG, and cartridges from the initial tests
with the Israeli headstamp
The Experimenting  was dropped after a few
years as the U.S. Armed Forces lost interest
in
the Project.
The Colt HeadStamp was made by IVI of
Canada, the Remington (R-P) Head Stamp
was also loaded by Colt.
