Tula 9mm ammo

Problem is not the cases but most often the bullets are iron clad lead with a copper wash.
Now that will "iron" out a barrel fast. No rifling at all in the AR's after 5k shots with iron bullets, and that from a hard chrome plated barrel.

We're talking about lugers, not ARs; the steel case IS the problem in a luger; as has been pointed out before- primarily due to the obduration ring the the chambers(before 1940).

Practically, there is no good reason to use steel case ammo in a luger; if one can afford a luger, one should be able to afford brass case ammo!
