Can't speak for their .45 rounds, but I've gone thru 400-600 rounds of Ammo Inc in 9mm. Shot it in my G19, Hellcat, and a couple rented pistols. Haven't experienced any problems with it. Seems to be relatively clean shooting ammo as well.
Just don't buy it from Locked & Loaded. (Been getting spam from them) From the reviews I've read, They're pretty much a scam site as far as I can tell.
