M&P 10 - FTF w/Steel Case Ammo

[Twin]

So I tried running some Wolf steel case through the M&P 10 I got the other day, and it won't eat it. My research had indicated it wouldn't be a problem, but here I am. Does everyone here run brass? Or am I going to be compelled to try five different steel loads to see if it likes any of them?

1.   She looks dry.   Get some lube in there.   
2.  Tried multiple mags?

Gotta second Capbyrd about the lube and trying different mags to ensure it isn’t a mag issue. Other than that, I’ve got nothing for the ammo itself as I don’t feed steel to any of my guns.

I've got 500 rds of Tula steel case for sale

I had to learn the hard way. That Wolf steel cased junk broke the extractor in my M1 Carbine twice! 

I won't use any steel case ammo in any of my guns anymore.

My Saiga .223 eats steel case for every meal.  My ARs are bit more picky.

I had the same problem in my colt 901 with privi (brass), it will shoot wolf all day long.

BCG looks a bit dry and dirty...clean it, lube it, and report back!

I lubed it pretty aggressively, and the issue nearly went away. 

I had one FTF, but the rest of the mag was sent just fine. Last round hold open also failed. But that's progress from not feeding at all. I'll clean it thoroughly and lube it up some more, and see if the issue goes away entirely.

Tried different mags yet?

No, I only have pmags. But the last round hold open failing did start me thinking that perhaps the mag doesn't sit high enough. Thus causing the rounds to get stripped out of the mag willy nilly, as well as the follower not being high enough to engage the hold open mechanism.  In addition, sometimes it will fail to strip a round from mag entirely, and I'll be met with a click, and have to cycle the action.

I was under the impression Pmags were quality AR-10 magazines. Any recommendations?

my experience has been they are overall good but they do have their slip ups from time to time....I would highly suggest trying a different brand if you can find one for cheap just to rule that out.... S&W's are usually pretty much GTG in my experience.
