I doubt Jeff used a microscope to confirm/deny thick copper "plating". Without an objective analysis who's to say the pellet flakes referenced in his report were flaked heavy copper or bismuth flakes with a copper wash .....I suppose you could call that thin electroplating. Just my thinking but when someone says plating I'm remembering the relatively thick chromium plating on steel automobile bumpers before they changed bumpers to polymers; if not done properly that chrome though relatively thick would flake off in strips with exposure and over time.
Another point I wonder about is if Boss uses relatively pure elemental Bismuth or an alloy like the 90% Bismuth/10% Tin composition as in the excellent Eley-Hawk non-tox shotshells. They tested well at various distances for efficiency (patterning) and penetration in dry pine.
Another question, as I understand it the USFWS has a list of approved non-tox pellets. If anyone is talking with Boss you might ask if Copper (a heavy metal) is on that list for use while waterfowl hunting.
