having just 2 segments and having them be full length, having them be "hard" (relative to lead) solid copper segments, and having the benefit of the Mach II velocity's ability to generate a temporary gas cavity that actually WiLL destroy fragile organ tisse (especially in the area between the 2 diverging wound tracks). So the effect is a wound track about 3/4" wide one way and 1.5" wide the other way.

Are you measuring that energy dissipation at the muzzle or at yardage? Is that a special handload or can it be purchased online?
