Hybrid: 7.62X39 to .44 Mag.
These are two .44 Mag bullets (260gr and 202gr) made with my hybrid method out of 7.62X39 brass cases. They have pure lead cores.
The expanded bullets were fired into water saturated fine sand. The velocities were 1300fps and 1540fps. Distance 8 yards.
Retained weights are 225 and 145gr. Expanded diameters average .700" on both weights.
They can be seen on the album page.
