Do you have any proof to back that up or are you just circle jerking what the internet says. I’ve been shooting steel case stuff for going on almost 20 years and I have yet to see any damage.
https://www.youtube.com/watch?v=qBAh_8usXBI (Sorry it’s a Jewtube video) This guy does some actual hardness testing on steel cases and the results seem to say otherwise.
And here is some data on the bimetal jackets used on most steel case ammo and barrel life.

The only guns of mine I try not to shoot steel case out of is the ones with fluted chambers as the steel cases don’t expand as easy and it makes the guns a tad dirtier. But I would shoot them in a heartbeat if that is all I had.
True, that statement comes from my dad maybe 40 years ago. His 1911 needed work done and I remember him blaming it on the ammo.
Edit: ten seconds of internet searching would have been smart for me to do: https://survivalmag.net/tulammo-review/
