I tried some of that Tulammo in .223 55grain fmj last week and I've got to say I am impressed. For ammo that is $5 a box it's pretty good. I had no malfunctions in my bushmaster M4 and it was pretty accurate. It was no dirtier than remington umc and did no damage to any part of my gun. I will say it seemed loaded a little lighter than umc, but plenty enough to cycle the action. It even had less odor than umc ammo and wasn't smoky like some cheap ammo.
I even did the "pliers test" and from what I could tell the steel is a tiny bit harder than brass, but not by much at all. Definitely not enough to round out an extractor, unless it's made of pot metal. I definitely plan on buying some more for cheap practice ammo.
