Primers not going into some GGG .223 cases

[The Lord Flashheart]

I have a spare primer pocket reamer (stop laughing in the cheap seats) that I am never going to use.

Pm your address and I'll pop it in the post for you.

That's very generous of you, but as I do already have one it would perhaps be unreasonable to accept.

Now I understand that the original primers were crimped, I think I know how to fix the problem.

But if I can't I'll get in contact with Kenny.

No worries.

Did you also buy it under the impression that it was a primer pocket uniformer too?

Part of kit, but yes I did, having looked at it there is no cutting edge for the crimp though. The internal deburring tool in the same set does the job. I did also learn that if you seat the primer when the crimp, or part of it, is still present, you get a nice piece of very sharp brass swarf to stick in your thumb.

Both of those are in the Lyman set of tools, the top one should, I think, remove the crimp but does not seem to do so completely, but the countersink type case inside deburring tool gets the rest off now I know I need to do it.

Swaging sounds like the way forward for volume case prep in that case, when they crimp it also displaces some material into the primer pocket.

I have to say I've moved to swaging with the RCBS swaging die... I originally tried a countersink bit which worked ok, but some primers were still tight to get in...I then bought the reamers and still wasn't completely happy, so moved on to the swaging die... no problems since then.

Remington say don't use their 6 1/2 small rifle primers in .223. There is a warning (in very small print!) on the edge of box.

I use the top one mounted in a battery drill, it takes a surprising amount of work to get some cases to cut.

The top one in my lathe at 2000rpm doesn't take long to remove any amount of crimp!

Edit - Mines made by Hornady and is rather keen.

OK so I'm a savage: I use the pointy nose on my RCBS case neck deburring tool to remove primer pocket crimps.
