New life for old brass?

[Fred @ Bison Tactical]

I need some ideas. Also - this is for the future, not dependent on current reloading component availability, so I know things are difficult to find...

My question is, I have some older 6mm Dasher brass (Lapua fireformed BR brass). I shot CCI 450's in this, and some of the primer pockets are getting loose. I know some primers are "wider" or fit tighter into the pockets than others. Are they any that fit more tightly than the CCI 450's so I can take up some of the space that is widening due to these cases getting old (being shot hot)?

My Dasher brass never really grew longer, so I am not too worried about case head separation.

TIGHTEN PRIMER POCKETS, here's how.

First of all, this won't work on extremely over pressured brass! If your primer pockets are getting loose from multiple firings (general wear and tear) this will work. I have a 4H ( HARDENED ) hex head bolt of the appropriate length wrapped with tape at the cartrige neck area length, and...

Fwiw, I started this thread years ago. I still use this operation to this day.
Give it a shot. Not much to loose.

Will the same size bearing work with small primer pockets you think?

One way to find out. I'd maybe buy a smaller one to try, see which one is better.

Someone made a tool to tighten primer pockets. I think they posted about here when Snipershide was with Scout. I don't remember what they called it.

I actually tried this a while back with some 338 edge brass that I got slightly carried away with.
It works!
I use a 5/8 ball I think and a drill blank with a brass bushing to keep it aligned and not banging on the neck.

I bought some pin gauges to measure the pockets.

I notice the CCI military stuff with the harder cup seems to fit tighter than the regular primers. I ordered some off brownells not long ago.
