After looking at the cases I inherited, about 1/2 of the cracked Cases had not been shot & were cracked during the resizing effort. The reason I know is that there were some 74-75mm cases, some of them loaded, that have cracks & I am pretty sure those will not chamber.

Velocity w/ 130 grain lead cast bullet & 27 grains of VV N140 is about spot on 2200 m/s.

Hochachtungsvoll,
