I was helping my friend who is new to reloading today. We were loading for his 7mm Rem Mag. He had a bunch of 150 gr Hornady CX in front of 64 gr of H4831 (the minimum was 62gr and the maximum was 68gr according to Hodgdon). He didn't have any brass so I gave him some once fired Hornady that came with a bunch of federal that I bought. We loaded them 10, 30, and 60 thousanths of an inch off the lands, all of the OALs were within a thosandth. Then we went to the range, lets just say it wasn't pretty, he fired the first shot and couldn't get the bolt open. I had to hit it with the palm of my hand to get it to open, I was thinking that we had a pressure spike but the brass had NO signs of pressure at all so thinking that it might be a fluke we loaded another. The same thing happened. I looked at the brass in the sunlight and the only thing off that I could see was just ahead of the belt you could see where it had been stuck, it wasn't bulged, it was just stuck. Anyone had this happen before?
