I want to discuss this, as well. Fascinating concept. I approach it from the angle of trying to get the best external ballistics from mass-produced, hardened steel core general-purpose bullet for something like the 65G.
My concept is a steel arrowhead like M855A1 — but with a longer tail — set into what is, basically, a solid copper "sabot."
I'm not wild about the super light alloys such as aluminum because I'm skeptical of their penetration in general-purpose combat scenarios.
Density of lead is 11.34 g/m3. Density of copper is 8.96. Steel 8.0. Aluminum 2.7 — if memory serves.
