If a gun won’t shoot steel reliably, it doesn’t deserve brass imo. Wolf is my preferred steel cased stuff and is absolutely good to go as I stated in another thread 2 min ago.
As far as wear and tear, let me know when you wear out a barrel or break an extractor and then let me know if the cost to replace the worn part was less or more than you saved in ammo.
Using pre-panic prices, I saved roughly $20 per case on Wolf vs cheap brass 9mm. With my first case I bought a new extractor just in case this new crappy ammo destroyed my gun. It didn’t.
With .223 it was about $100 per case difference. 3k rounds and you’ve saved enough for a new barrel, gas tube, block, and extractor.
Shoot what you like, but fiscally it’s the better option if you plan on shooting regularly or in volume.
