I went out a couple weeks ago with a bunch of guns and was having a great time shooting. I made about 80 500 magnum bullets and noticed that two of them had a hang fire, one was not delayed much but the other one was about a full second. This is the first time I bhave had this happen and it is a weird thing to experience especially from such a heavy hitter. having it go off kind of unexpected kinda catches you off guard. I was wondering what might have caused this to happen. I do all steps on the press including priming so maybe something got into the primer? I don't know. Thanks
