Mine does. I included one box of S&B in the first outing of 200rds. FWIW, my .45 didn't choke on any of the ammo used. I will say that it produced quite a bit more smoke and fouling than the Rem. UMC, Blazer Brass or Federal.
That's surprising. I find the Remington UMC to be the dirtiest ammo I have ever used. I have used S&B in 9mm and .223 and found it to be pretty clean and pretty hot. Maybe the powder they use for the .45 loading is the culprit.
