I used to reload a lot of .30 Carbine. I have never fired steel cased ammo from any of my M1 Carbines. The carbine extractor is abusive to the case rims as it rides over. A good test would be to shoot 10 new brass cases and inspect the rims. Shoot 10 steel cases and inspect. IF the steel cases are soft and show some damage, the extractor must be harder?? IF the steel cases are NOT damaged would, it be safe to say that the extractor will suffer in the long term?
Would love to hear/see results of a comparison.
