I've been regaled by a few Dallas PD officers of a shooting they called either "The I-30 Shooting" or "The Cockrell Hill Shooting" (seeing as Cockrell Hill Rd begins at I-30, both work). It was around 1990, and DPD had been issuing 9mm for a couple of years (SIG 226s, though Beretta 92s were authorized, and there were still plenty of .38s and .357mags out there).
Apparently some coked out fella of large proportions got into a rolling gun fight westbound on I-30, nobody was hit, but I was told his car was disabled just east of Cockrell Hill Rd. He gets out, wearing a white t-shirt, and starts shooting at officers. My close buddy says the white t-shirt went red from all the hits, front and back, as bullets were plugging with t-shirt and trucking right on through. There was some good placement considering how far back the patrol cars and officers were from the badguy. I have been told many different numbers on how many hits by guys that were and werent there. For some reason there was a pause, and the guy looked at himself and the mess he was, and decided to just walk away. A DPD officer there (first name: Nino), who was carrying a S&W 66 loaded with 145gr Winnie Silvertips (I thought it was coolest gun in the world, until he got a 686, and later a 686+) at the time, that had family across the street told me my dad one time, the guy literally spun around and walked away like he hadnt a care in the world. Officers pursued at a distance, and the guy spun back around and dropped.
The other officers proceeded towards him cautiously and the guy raised a gun, so an officer plugged him with a 12 gauge loaded with 00. The guy flinched, winced, and tried again, and got another loaded of 00 from another officer. Then it was over.
Turns out the guy wasnt reloading, he was just grabbing other guns out of a paperbag in the front seat.
DPD switched from that load, Hornady 115gr XTP, to the Remington 115gr+P+ JHP (9mm Treasury Load). Then, around 1996 they went to 147gr Winchester Rangers, Rangers SXTs, then Ranger Talons. This year they moved to 135gr+P Hornady Critical Duty. Around the time they switched to heavier 9mm loads, they authorized .357sig. I had an empty box of the 115gr Hornady XTP load, and a partial of the Remington offering al with faded red stamps marked "For DPD Use Only", but I lost them in a house fire a few years ago (I also lost a rare box of Federal .357sig 150gr. JHPs in the copper and blue box).
