[LtCol Henderson Marriott]

This is the somewhat modified article by the same author. He did his own research and may have updated it. Both patterning % and density is covered as well as the important factor of penetration. Boss is well treated, with later mention of "Warchief" bismuth shell development.
The jury may remain out on Boss copper plated bismuth shot performance and disintegration. If the problem is experienced by other known hunters or PGCA members,
please let us know.

As an aside, there is at least one other small TSS/Bismuth shot shell manufacturer
that advertises copper-plated bismuth loaded shells. If so, these may be surface washed or treated-rather than plated to avoid patent infringement with BOSS.
More due diligence inquiry to follow.
