Are not power belt platinums considered jacketed?
Believe they're just plated. Hornady FPBs are jacketed, albeit a thin jacket. I've recovered a few from target berms that separated completely, but there's a big hunk of lead in that thin jacket.
"PowerBelt Platinum AeroTip Bullets utilize an advanced plating technology, a more aggressive bullet shape and a fluted gas check design that combine to make the Platinum Series the best performing high velocity PowerBelt ever."
