I no longer shoot steel case in anything that has an expensive, difficult to replace, or rare barrel.

It's discouraging to hear that 5.45 is doing it too. At least no lathing necessary for those replacement barrels.

Western military ball in 5.56 is much easier on barrels it seems.

5.45 lasts quite a bit longer because it's a lower pressure round overall. However once they open up to a certain point, I just retire them or replace them.
