Hello Gents ,so am having issues shooting SCORE trap shells.Thought it might be my gun (model 12) but now am thinking I might have some primer issues.It is so random that it drives me crazy but am looking to see if anyone else has had issues as well. So every 2-5 boxes will get a misfire,primer hit no bang,reload the same shell and bang.The gun I believe now is not the issue as the primer seems to be getting a good "hit" .Could there be a run of bad shells as I shot multiplex and went through a case including practice no issue. Never had this before ,??Have 20 cases left so am hoping its isolated ..
