I've only fired 40 rounds through my M&P, 2 mags loaded 20 each fired back to back, and I had no issues what so ever. I wouldn't hesitate to shoot a few boxes now and again, but my AR isn't set up for extreme precision or anything like that so a little extra junk food doesn't hurt it.
I'll shoot steel in an imported (cheap) AK, but not in my (expensive) AR's.
When Noveske and CMMG say steel will void the warranty on my barrels I've got to believe there's a reason.
I am just not seeing how that could have any merit at all. :confused:
How do brass cartridge cases clean blowback residue from barrel chambers?
What is the science behind that?

I don't know that anybody knows the exact reason, just that the accepted procedure is to not mix flavors unless you do a thorough chamber cleaning between, or just flat out don't mix flavors during a shooting session.
Copper or brass washed steel cased bullets, OK in chrome, not a good plan in stainless. Depends on the thickness of the coating of the bullet. Not a fan of steel in my bullets anyhow, limits where you can shoot, and what targets you can shoot. Range masters get bitchy when you start tearing up their poppers and gongs with steel core.
I run Tulammo all the time, I just make sure to give a few rotations with a chamber brush and run a bore snake through my barrel afterwards. No problems. If I was taking a carbine class or needed some reliable ammo, it would be brass cases all the way. Steel case just for practice.
