agreed, but its more like tens of thousands of rounds, not hundreds. People complain that they wear out extractors, bolt faces, barrels, whatever. Lets say you get tula 5.56 at $.30 a round and brass at $.50 a round. over 5000 rounds that's a cost savings of $1000. You could buy a new AR for that money with room to spare. And these guys want to spend several thousand dollars on brass ammo so......what? So they can save the replacement of a $5 extractor? Seriously? How does that make sense? Even if you didn't shoot that much, the $200 you save per 1000 rounds would pay for a new bolt, extractor and a gas tube. Its this new thing called math people. Look into it.from what i understand, the difference between shooting steel and brass is that you will get more life out of the gun using brass generally, but its a difference realized after thousands of rounds, not hundreds. also steel case damages the extractor more than the firing pin. i guess it would be first thing needed to be replaced, but again this is the difference between 10K and 12K rounds or more
