I just fired my first 100 rounds in my Steyr M40-A1, I had one FTE and one FTF although there is a clear strike on the primer. I used a readily available ARMSCOR 180gr. FMJ. It's a good ammo company here in the Philippines. However, I would like to ask if anyone experienced bent casings. My shells were mostly d-shaped after firing. And also the occasional shell-in-the-face action. 90% of my shells were deformed. Any insight? i do have some pics but I don't know how to post it.
