I read that article about steel case being hard on the barrel, but the problem really seemed separate from the case--it was that the powder eroded the gas hole/vent and had nothing to do with steel cases.
The issue should be: how much did you spend on your gun and is it worth shooting crap ammo through it?
Personally, I have tried reloading steel cases and found that they reloaded just fine; however, when fired the gun sort of "stuttered" like it was having a hard time extracting the case and the bullets hit far from where brass-case ammo hit. I could well see poor reliability in .223 and, possibly, extractor breakage.
So, if all you want to do is spray bullets around, don't buy an expensive gun or shoot a .223/5.56.
