Evan, this is what Springfield says about steel cased ammo.... Avoid using steel case ammo, it is VERY hard on your chamber and can reduce the life span of your rifle...... But plenty of people have used steel cased ammo with varying results. Some say it jams often with steel cased ammo and some say it runs fine. So honestly just depends on the rifle. Personally I'd probably avoid steel cased ammo unless it's all you can find or have a bunch stocked up but I'd try to keep it to a minimum. Hope this helps.

Hi Evan and welcome. I have an M1A Rifle and have no issues with TULA Steel Case Ammo. It is not as accurate as the good brass stuff but shoots just fine. Cheers and stay safe!
