"if it moves, salute it, if it doesn't, paint it!"
The US Army used that phrase differently.
If it moves, shoot it. If it doesn't move, pick it up. If you can't pick it up, paint it.
Steel cases? Never reloaded them for rifle.
I have a bunch of them reloaded in .45 acp. Been reloading them for years for the .45's. Zero issues up to now. No split case mouths, no nothing except functioning like the brass cases - meaning you won't know it's brass till you pick it up off the ground.
In the AR world many say that shooting steel cased ammo (not reloading it, just shooting the factory stuff) results in having to clean the chamber better and more often to prevent extraction problems. Due to the previously mentioned difference in case mouth/shoulder expansion/sealiing vs. brass cases. The dirt/crud from the burning powder moves further into the chamber down the outside of the steel case.
I have questioned increased die wear while reloading the .45 acp brass. If I'm using case lube then the metal of the case being resized should never touch the steel of the resizing die. There should be a barrier of resizing lube between the case and the die. Not necessarily the case mouth expander and the case (though I to put some lube on the inside of a case mouth every so often) as many of the case mouth expander balls are carbide or very hard steel, depending on the brand and cost of the die set.
One thing just hit me. If (and I do believe it) the steel cases don't expand/seal like the brass cases then the steel cases shouldn't stretch much or fail due to case stretch like a brass case.
I do believe trimming the steel cases (on a bottle necked rifle case) would be tough on your case trimmers though. No lube used for that step. And a much smaller contact surface between the steel and the cutter head.
