I get so confused. I have never had a stuck case using steel cased ammunition. In fact I have had only 3 issues w/ steel cased ammunition in thousands of rounds (2 short strokes, and one failure to feed w/ a HP round. What am I doing wrong? Have I just been extremely lucky? Someone help me understand. What manufacture of AR are some of you using when having issues w/ steel cased ammunition? Wanna kill these ads? We can help!
