Balance.
A weight rear bias is more stable.
If there is the slightest wobble, forward weight enhances it.
Rear helps to attenuate it.
a solid bullet would perform better.
Show me the benchrest records to prove this.
I can't , i am convinced experts at hornady know what they are doing , just wanted to get a second opinion from 24CF members.
Ultra-long-range match bullets for the big boomers are made of lathed mono-metal. It doesn't matter to me, but I am guessing that mono-metal target bullets can be lathed in a way that allows them to travel down the bore with less resistance and less deformation, thus producing more consistent BC over the flight of the bullet. I don't think this matters for bench rest, but it likely does at a mile and beyond.
