I looked through about a hundred or so empties, and they are all pretty much exactly the same with no crimp. I still think what looks like a crimp in that one picture is not a crimp, but was rather done by the stud that pushes the primer into the pocket. Out of 250 I probably have 20 or so that are similar to this, these are the worst ones. Some of the rounds where the primers were messed up.
The Federal has a little more of a rounded edge going into the primer pocket, where the Winchester is more squared off. Here's a picture of the Winchester brass next to the Federal. I was mainly wondering if anyone else had run into this problem.
Anybody have any other suggestions such as using different primers, etc.? I have CCI and Winchester small pistol primers that I could use instead. Would swaging this brass or reaming the primer pocket help this problem any? I hate to think that I can't use this brass, as I have more of this than anything else. The thread about primer detonation makes me thankful I didn't have one of those. I realize I probably "forced" a few of these in too much, and have learned from that. I ruined a few primers, and have some rounds where the primers went in, but are messed up. I'd say about 10 out of 100 would give me problems with the Winchester brass. I switched over to Federal brass about half way through and didn't have a single problem. I'm assuming from the primers being pushed in. ETA: I forgot to mention, there was a lot of brass shavings that got everywhere while using the Winchester brass. I am using a Dillon 650 for loading these rounds.
I ran into a problem with Winchester 9mm brass (not crimped) and Federal small pistol primers yesterday where most of the primers would go in ok, but every now and then one wouldn't go in or it would go in with a "crunch".
