OK, I've done some searching on the web and see that removing a crimp from the primer pocket is necessary before re-priming.
However, I didn't see a lot of detail on HOW to do this?

There is some mention of spendy tools and stuff, but not real good solid info.

Question: HOW do you remove the crimp??

This is FC brass which I'm told is good.
 
One option is to use a swaging tool in your press. The other is to use a chamfering tool. I have found that even after using an RCBS swager, I still need to touch the edge of the pocket with a chamfering tool for primers to seat easily.
 
i use the chamfering tool- the only real way around it is to use commercial brass- i know it's a pita, but you gotta do it- otherwise you get folded primers, or they won't seat at all, all kinds of things- what it is is a small brass ring enclosing the primer and when you decap, the primer is forced past this because it's softer metal- when you use your chamfering tool, you cut away the ring because the chamfering tool is steel, which cuts brass easily- the swager forces the ring back to where it came from- either method is effective- in a pinch, you can also use a knife or drill bit by hand- when i'm doing this, i'm also chamfering the case necks, so it's just an extra step
as to HOW YOU DO THIS, STICK THE chamfering tool in the primer pocket and turn
the swager uses a button in a similar fashion, but no turning- you just force it into the primer hole and back out

Um, the best way I know how to decrimp primer pockets is to find someone with a 1050 with that feature that will let you use it. Saving that, RCBS makes a primer pocket de-crimp tool but it's slow going. Dillon makes a similar bench mounted tool, but since I have both of the latter, the RCBS tool seems to work faster for me. You use it on a single stage press.
 
If I have a small number to do I just just use an RCBS case neck chamfering tool. If I have a lot to do I chuck a countersink in my drill press, lower the table and just touch the inverted case against the countersink. It makes fast work of the job and works fine.
 
That's all? I have um... 15 gallons of once fired 223 Military brass to do.. Need to find a rainy day when I'm not doing other stuff to get it all processed :runaway: It might be a good idea for me to get one of those Gracey case trimmers while I'm at it :D
 
If you are cutting the crimp out with power, be careful not to cut too deeply. If I am going to use a chamfering tool, I mount it in a lathe, running at a lower rpm.
If I use the RCBS swager, I follow up with a primer pocket uniforming tool, also running in the lathe.
 
OK, I just took my manual primer case reaming tool, and put the bit from it in my battery powered drill. Reamed 'em out for a few seconds each, and voila, primers fit nicely.

Yes, only 1000 or so cases... Shouldn't take me more than a month to get 'em all ready....... :rolleyes:


LOL :D
 
What is that uniforming tool and where can I buy it?
Need to decrimp some 500-700 of 223/5.56 brass

Also, where can I buy a 223 lapping tool?
 
ok i need to buy something not press mounted, as i have a lee loadmaster, not a single stage press. what are some crimp tools i can buy to put into a drill, like what are they called? also a hand held model. thanks guys.

Hornady makes a pocket swaging tool? For around $10? Really? Is it a press mounted like the RCBS? You mean I can return my unused (so far) SuperSwage 600 and bank the $80 difference? :)
