Federal 223 Brass

[Ram Ringer]

I have some factory 223 once fired brass that I would like to reload, but when I deprimed the brass I noticed a little ring inside the primer hole which does not allow a new primer to be seated. Does anyone know how to remove this?

Thanks

Get a primer pocket reamer.  Hornady and others make'em.

You can even chuck it in a drill if ya wanna make it faster.


edit: this would be called a "crimped" primer btw

Sounds like mil-spec "crimped primer pockets" to me.

Google found me this: http://www.midwayusa.com/product/447022/rcbs-primer-pocket-swager-combo

The RCBS Primer Pocket Swager Combo quickly removes primer pocket crimp from military cases. Unlike reaming, the Pocket Swager Kit forms a perfectly round pocket that is the correct dimensions for American boxer-type primers. Combo comes with swaging heads for both large and small primer pockets. Not for use on progressive presses.

Yep what the other 2 said. First time I reloaded that brass I ruined several primers trying to fit them into that itty bitty hole. Bought the lyman case prep kit and voila, much better priming.

Ream it and go.  beware some of the flash holes are off-center, and if you try to roll crimp while seating the bullet the shoulder may collapse.  I have quite a few with crushed shoulders, i'm going to switch from roll crimp to collet crimp.

I use a 45 degree countersink meant for a milling machine, chucked into a cordless drill.  It's probably not as consistent as swaging the pocket with a Dillon tool, but it's FAST.  It takes about the same time to drop the finished case and pick up a new one as it does to actually cut out the crimp.  Hit it with the drill and a little ring of brass comes flying off.

Thanks for the help, Thats what I thought I needed. In fact I do have the military crimp remover attachments for the RCBS Trim Mate, but they never seem to remove the whole crimp. I will have to see about one of the swaging tools.

Thanks
