This is a drawing of one of two different Squeeze bore 9mm P loads produced
in Sweden. This load has a turned steel bullet. There is also a load with a turned
GM bullet with a blunt ogive at the bullet tip. Apparently both were produced in
the 1967 time frame for tests with a 9mm/6.5mm squeeze bore version of the
Swedish K (Carl Gustav M/45) machine pistol.

Any further information on this experiment would be greatly appreciated.
