Did not know about that information. Can you elaborate? Thanks
Hornady changed the Amax & match bullets jacket to the "AMP" process; which according to them is also used in the Z; but not stated about the V.
Instead of a standard cup-n-core, they plate on the copper. I'm not certain the entire thing is plated, possibly a partial cup, but the bulk being plated. Similar process to what Speer started quite some time ago.
