30-06 loose pockets and pierced primers

[PhillipM]

I loaded 60 LC cases with more than 10 loads and 60 once fired Remington with a load of 46.5 imr 4895 with a 155 gn bullet and WLR primers. The LC cases have some pierced primers on the radius of the primer and a loose pocket. Please explain why cases with loose pockets have primers that pierce at the radius.

did you length size the old brass ??
and what did you shoot them in

[PhillipM]

I've been using the RCBS X-Die, trim once and forget it. This happened on the same shoot with an M1 and a 1903. Both have minimal headspace.

I'm guessing what you are seeing is gas leakage around the primer pocket from an eroded primer pocket. In my guns this results in an eroded breech face, primer pocket diameter.

Ten loadings is about all your going to be getting and it's time to recycle those cases. I think Doug is right and leakage around the primer is what your seeing.

I know, we hate to see them go, but they can only take so much.

The x die does stop cases from stretching thereby needing a trim, thereby leading to the thin spot above the case head. I knew life would be ended by a loose pocket or split neck, but I'm seeing actual pinholes in the primers, Winchester LR's. Some of the Korean brass I've loaded has had a little leakage around the pocket, but this is new. Yes is was a PITA to photograph this, lol!

Try some CCI primers. They seem to be tougher and fit tighter in the pocket. That's why I switched to them.

Check the very tip of your firing pins . The gas leakage might have eroded and roughened the tips , giving a sharp burr that's leading to the piercing .

Its sounds like your an experienced reloader but just to cover the basics I assume you are getting a full seat on the primers...correct. Similar issue came up with friend who was a novice. In inspecting some of his reloads he hand about 1 in 10 with not fully seated primers. No offense if you've loaded for years but this reminded me of that so I mentioned it.
