Some guns run steel without a hiccup. Mostly combloc guns like aks, SKS and Makarov pistols. Try feeding it in a striker fired pistol like a Glock with an aftermarket trigger bar and you'll have the world's most expensive paperweight. Hammer fired guns will usually run it just fine but just as others have said many negatives including the case mouth not sealing, bimetal bullets that spark and potentially ricochet if you shoot at steel plates, extractor and ejector wear, etc.
I bought and run through many rounds of it over the years but now I keep it exclusively for aks and my VZ58s. Everything else is on an all brass diet.
