I've ordered the large and small primer pocket correction tools (aka primer pocket uniformer) from K&M; we'll see if those will help, or if they're worth the effort: https://kmshooting.com/product/small-pi ... tion-tool/
Well, the tools arrived quickly but it took a while for my lazy ass to try them out.
Here's an example of one of my "bad" pieces of Lake City .223 brass. See how the primer pocket gauge sticks out of the pocket just a little? That means that the pocket is too shallow:
Now if I stick that same piece of brass onto the K&M tool, there's a gap of about that same amount:
And when you fire that sucker up, here's what it looks like:
The K&M tool is set to a depth of 0.122"; recall from earlier in the thread that a small primer pocket should be 0.117-0.123" deep. I did maybe 50 cases, and it removed material from all of them. The example in the pics and video above was among the worst of the bunch.
Very helpful tips, thanks for posting the photos and the primer pocket depth measurements.

Has this come up in this thread? After swaging I use the PP uniformer on all cases. Mine is not adjustable like the one in the video. Food for thought...

K&M makes quality tools for precision reloading. I came across some of those primer pocket correction tools but they are for large primer pockets, I have them for sale...

weird...I simply use a reamer to remove the extra metal from the crimp, after reaming, some are a little tight going in, but they don't get smashed. So far no high primers or mis-fires.
Reaming is not the way this should be done.
I’ve been using a rcbs swager die for everything for 5 plus years with no problems
No go gage Tight primers Never flush , always below
I use a hand primer or press, depending what I’m doing. You can feel the difference in a seated or a “maybe” one, then just run it again.
As I mentioned in an earlier post I’ve used both the Dillon and the RCBS swagger and I believe that’s the Dillon was the most troublesome. I too have never used a no go, go gauge for primer pockets because I never really had a problem, If by chance I did notice a primer that was not seated to my satisfaction then I would run it back through to make sure it wasn’t an operator error and if it’s still protruding I would deprime it and throw the case in the recycle bucket. It has rarely happened so it is not worth my time to dig into it further because after all it’s just a piece of brass, it could be defective so I throw it away. Done...
