Bulging Primer Pockets

[mbeavers1]

So I seem to have had a mishap with my sizing die and the stem was a bit too long and bottomed out on the flash hole. It was so perfectly set that it happened right as the die bottomed out on the shell holder so I never noticed it.

Now I have a whole bunch of brass...like 400ish pieces of Lapua...that look like this. OUCH.

I tried to clean some up with a Sinclair PPU tool but it seemed to cut a lot of brass.

Think it's salvageable or junked?

ouch...I probably would have tried something like the RCBS primer pocket swager...that is a button pressed into the outside....that may have pushed the bulge back to even.....or the Dillion Super Swage....worth a shot.

Only cut 1....plenty left to experiment with!

If it still holds a primer cut the bottom out with a pocket unifier and run it.

Think this is where I'm heading.

If you can seat a primer flush, I'd load and fire 10 for a test.
Irrelevant here, but in the last 4 yrs, I have gotten my share of Lapua and Norma brass that were impossible to uniform the pockets till after 3 firings, they were that deep.
Maybe i am off base, but I don't think i would try uniform the pockets on those cases.

I've used that in the past.....but if you don't own that...and you own a Dillon Super Swage...I'd use it.

What do you see as the downside of trying to uniform?

Your expander ball is rounded at the bottom, so closest to the hole is pushed out or protruding more, no reason to thin that material.
