Best if any primer pocket fix ?

I have some 7 Dakota brass that is on its third firing and noticed this morning as I was prepping cases, that just a few primers were going in way to easy and would just drop out if I rapped them on the bench. I knurled the outside edge of the pocket and it may or may not work for this firing. Has anyone peined the pockets or other fixes?

I would discard those cases to avoid blown primers. Cases are cheap, eyes are priceless.

I'd be looking to find out why it is happening, as much as fixing it.

Third firing?? Sounds like you have a rather warm load there.

Yep, I would toss them out and buy new brass. Not worth getting hurt over.

One more recommendation for safety: Toss them. I'd very seriously consider reducing the load a bit.

A company called RW Hart offers a tool to salvage those primer pockets. I can't recommend the tool, but the company has an excellent reputation.

I've got 6 or 7 firings on my WSM cases and some are just now starting to loosen a hair.

Brass is cheap, a new breech is not.
I had the same on some Major 9 loads and obtained a nice case of breech erosion, i.e. pitting due to gas escaping between the primer and the primer pocket. I switched to a little softer primers (better seal when firing) and I am chunking brass with loose primer pockets. No additional breech erosion since. Do you have signs of pressure on your spent primers? Any photos?
