I found this on the inturb-web, so it must be true:
"These are from PMC and were called UltraMag. They were sold briefly in the '80's before their brass bullet design was banned as it could penetrate the Level II body armor worn by many law enforcement officers. As best as I can recall, the bullet weighed about 66 grains and was reported to hit about 1400 ft/sec from a 4" bbl. "
Tubular Bullets?

Black Talons were never "illegal". the Manufacture just pulled them and renamed them as "Ranger" or something similar and sold to "LE" only. IIRC, PMC Starfire are about the same thing as black talons.
They changed the coating color and renamed it Ranger SXT (Same X-act Thing)
