Me and my girl decided to go to the range yesterday, she shot about 100 rounds through her 732 and i noticed it was ejecting brass straight above her head after about 20 rounds. I stoped her stripped and cleaned the gun and looked it over didnt notice any issues, she shot it again and same thing, i know it wasnt weak ammo(used federal 71gr fmj) it was stuff we have used before. SO please can anyone give me some hints as to what might cause this!
