M&P and Steel Cases

[sdbran01]

I've recently purchased a M&P AR-15 and I'm new to AR platforms. Does anyone regularly shoot steel cases through there M&P or should I stick to Brass?

you should stick with brass cased ammunition. saves time and headache.

If your AR won't run steel cases, get rid of it.

i agree theres nothing wrong with steel casd ammo.

besides the increased chance of a stuck case? the steel doesnt expand like a brass case does. therefore carbon gets in-between said steel case and chamber, causing problems. the softer brass expands fully making that a non-issue.

youll get a stuck bolt running steel long before you do running brass. but then i guess that depends on how much you intend on shooting the rifle / designated purpose.

I was once in a carbine class where I saw five out of eleven AR's jam while using steel cased ammo. I know for a fact two of them were Spikes and one was an M&P.

Carbon builds up in that same spot with all ammo. This is the reason you clean your rifle. Also, have you ever measured the expansion difference between a steel case and a brass case? Or are you just repeating the usual hearsay?

I can believe this, but the question is whether or not those AR's were jamming previous to the class. I'm sure out of the sake of saving humiliation those AR owners said, "I've never had problems with this until running steel cases.", however you don't know what's really been going through that AR or when the last cleaning was done.



I've seen and shot hundreds of rounds of Tula through a Colt, Superior Arms, and a Rock River with no jams, no extraction issues, no stuck cases. I could go on and on with problems you could experience that I haven't. To each their own, but I've never had a single problem running steel cases. That's also to say I've never experienced anything but a double feed with brass cases, which was a mag problem.

Take a look at this video posted by Military Arms Channel https://www.indianagunowners.com/forums/military_arms_channel/234250-wolf_ammo_demonstration.html

Should help to answer a few questions, I shoot steel cases out of my ARs and have had no trouble.

 

[Limpy88]

i have shot 500 through mine with no problem.

 

[9mmfan]

I also shoot steel case, mostly Wolf, through my Smith AR with no problems what so ever.

 

[onesurveyor]

Shot no less than 5k of brown bear, silver bear, tula, and wolf through the ol bushy without a hickup.

If you shoot brass, lay out a tarp to catch it. Even if you don't reload, you can sell the brass to people who do. It would help make up the cost difference between the brass and the steel ammo.
