This may seem too simple to collectors of U.S. medium-caliber cartridges. There are 20mm Tround cartridges made by Veritay, Inc. that used a PGU-28 projectile. These are seen in at least fired and unfired rounds, and in purpose-made dummies. Veritay put a little card inside the Trounds to identify the round and to promote the company, I assume. I have documented at least three different lot numbers of the live/fired rounds. Apparently, all of them, live and dummy, use a PGU-28 20mm TP bullet/projo.
Does anyone have a drawing/description of a “PGU-28” bullet/projo? I think they may be dirt common, but I’m not sure. I’d sure like to have a couple of them if they are not gold.
The two 20mm Trounds shown are at 50% to save screen space. The cartridges are 6.7 inches long and 1.6 inches across a flat side.
