S&W position on steel cased ammo for M&P15

[Lineman73]

I was a bit cautious about using steel cased ammo in my new Smith & Wesson M&P15, so I fired off an e-mail to the S&W Customer Service Dept to inquire as to their official position on it's use.

Here is their response:

"Steel cases should be fine to run. Over many
thousands of rounds, steel will put a little more wear in the chamber of a gun
as it is a harder metal than brass. Just something to keep in mind."

Thanks,

As I'm looking at it, for a litte bit of practice or some knocking about the woods, it shouldn't cause any excessive wear. For the most part I'll stick to good old fashioned brass cases. I prefer PMC FMJ's for general use and Hornady TAP 75 gr FPD for "social work", but if the price is right I'll do some steel.

Over many thousands of rounds. Use it, save the money. Seems like most of the people on here never have a gun long enough to even put 1,000s of rounds through them LOL! Shoot the steel ammo and stockpile the brass!

its fine. just be sure to clean the chamber if going from steel to brass.
