Anyone shooting steel-cased ammo thru a S&W M&P or PSA AR?
I want (need?) another AR and there are some decent choices in my range, but I shoot a lot and have had to go with steel-cased ammo since the panic buying ensued. Does anyone own an M&P or PSA upper that gets a steady diet of steel-cased 5.56? How's it working for you? Any issues with extraction? Would reaming the chamber help, without raising additional issues?
I've only shot steel from a friend's RRA mid-length, and since the steel cases don't expand the rather dirty ammo (Wolf) was gunking up his chamber pretty badly. We mortored quite a few out in one day. However, I've read on the webz of S&Ws and Colts just burning thru the Russian stuff like butter, with not a single issue. Does anyone have recent experience running steel-cased 5.56 thru either of these two weapons?

I've ran several hundred rounds through my S&W M&P sport and it functions flawlessly. That was before I put my Bravo company stripped upper on.

Before I replaced my barrel on my M&P 15T I had over 10,000 rounds on it. I would say over 75% was wolf. I had a few cases stick in the chamber and had to mortar them out. The worst was Tula I had them stick all the time.
The barrel started off shooting 1.75" groups at 100 and 8 years and over 10,000 rounds later it shot 5" at 100 with a 3/9 scope. So I really thinks its true about the steel jacket wearing on the rifling. I also noticed that the flash finder was all gunked up with carbon.
I replaced the barrel with a Rainer arms select and it now shoots .80" at 100 with black hills 75gr match.
