The steel case ammo imported into the US does not have a "steel core" and is not any more capable of passing thru barriers as a result. What it does have is a "bi-metal" jacket instead of a copper jacket. The bi-metal jacket has iron as one of the metals, is not quite as soft as copper, and can spark more depending what the bullet hits. Indoor ranges are concerned about the possibility of such a spark starting a fire from all of the unburned powder and paper target remains that tend to accumulate. Another factor is that some ranges sell the dropped brass and steel casings are one more thing not desired.Does the cheap Tulammo in 9mm have a steel core? I didn't realize that. I thought it was mainly in the surlpus ammo.
In these parts, aluminum with either copper plated bullets or nylon/polymer coated bullets is the same price as the steel case ammo. Take a gander at Walmart for the Federal Aluminum cased ammo.
