Yeah, I liked the 1911 shooter near the beginning of the video as well. I didn't know Delta force shot smokey lead reloads. Okay, I don't know if they are reloads, but that has to be some of the smokiest military ball ammo I have seen except for the older corrosive RNL ball ammo. Note the lack of muzzle flip. Looks like light loads to me.
Probably game reloads. An old coworker of mine has shot IPSC with/against that guy. Says he pretty good, although he shoots more "combat/practical" style than a "race/competition" style. Notice his reloads...not your typical race-gun type shooting.
