As for demonstrating performance---
People keep telling me that M855A1 (the copper core trial winner, not the other one) is the new hotness, but I haven't managed to get any in my mitts.
I wonder what the grain weight would be for a similar 6.5 projectile which received M855A1 style treatment? Maybe 110 grains? If you replaced the rear copper slug with steel (cost reduction) and kept the front steel penetrator seperate (so it'd still snap on yaw), how much powder space would be lost? Maybe not that much?

I'm thinking that penetration with 6.5 sectional densities would be pretty darn good, and the new M855A1 is purported to be decently accurate to boot.
