Anybody had issues with this ammo or have a real reason I shouldn't use it? I had someone point it out to me and checked mine out and sure enough the test rounds from my G19 were steel casings :intrigued:
Don't know if this helps any, but not steel ammo in pistols, steel ammo in ARs:
An amount of the varnish vaporizes from each casing as it is fired, and recondenses all over the innards, attracting carbon and crud. I have seen AR gas tubes so clogged with carbon and varnish that there was no choice except to replace the gas tube and gas block. Wolf ammo was notorious for this.
In pistols, I would imagine (steel being harder than brass or nickel), the extractor claw could see accellerated wear.
As regards to reliability, I have never shot steel cased ammo thru any of my Glocks, and probably never will (personal preference).
