Steel case ammo is dirty because the steel does not expand like brass does to adequately seal off the chamber as the cartridge is fired. You are getting fouling back into the chamber. If you are using a weapon system that was deliberately engineered to foul the chamber as a matter of function, you need to be even more meticulous about cleaning the chamber.

Steel cases are not bad in and of themselves, but my gripe with Tula concerns the round I recently fired in my AKM that was loaded without powder. The primer alone launched the bullet into the bore but not far enough to allow the next round to be chambered. Who factory loads ammo without powder? This is quality control of the lowest order and totally unacceptable. This incident combined with the increasing frequency of dud rounds with healthy firing pin hits that I see turning up at ranges has made me decide that I will never trust Tula again. This is unfortunate because this ammo is extremely accurate in my AKM.
