Thanks for reaching out Darrell! We did publish an article about steel-cased ammo which you might find interesting:

If you've had trouble with certain brands of steel-cased ammo and don't believe more frequent failures to feed and extract are acceptable, then I'd advise against ordering more. Truth is, most steel-cased ammo is from Russia where it's all made in the same factories. For instance, this ammo has the TulAmmo headstamp, which means it's from the same factory that loads Tula ammo – which you may have already tried and disliked. Barnaul and Wolf are virtually indistinguishable from this ammo as well. It's a you-know-what chute: some firearms don't mind steel cased ammo at all (especially cheaper ones that are manufactured according to lower tolerances), while others just can't overcome steel's inability to contract back to its original dimensions following ignition.
