A few yrs back Wallis Labisky ran a rather extensive test of patternms using a wide variety of shot. Some which were unavailable in bulk for loading he opened factory shells for his supply. Of all the shot he tested the unplated "Diamond" out-performed all others. As i recall this was reported upon in the "Rifleman", but may have been "Handloader".
