Reloading 9mm Luger Brass. CCI Primers. Lee Hand Auto Primer. Steps taken in reloading. Removed Primer, Sized,Tumbled, Cleaned Primer Pocket, Installed new primer, Tapered, use HP-38 Powder, 4.5 gr. pressed in bullet to 1.65-1.69 OAL. This is my method for 9mm. Comments GOOD!
Now to my Problem, Started on new batch of brass given to me. approx. 500 casings. they are 9mm WCC 87 and primer will NOT go into primer pocket.
HELP IS NEEDED TO CORRECT THIS PROBLEM.
Thanks
 
Maybe crimped primer pocket? 9mm brass if often crimped to ensure a primer doesn't get rattled out should be they fired in a full auto SMG.

Is there a stamped circle or a few "punch marks" around the pocket? If so, that crimp will need to be removed. I use one of the orange handled Lyman hand tools to ream the crimp out of 5.56/223 pockets. Time consuming, but it works well.
 
Primer Don't Fit

Will it be ok to use small taper bit in a drill on slow?
And I really thank you for the info.:)
 
The headstamp indicates a military case with no doubt crimped primers. Yes, quite often a proper size drill bit will do a better and more consistent job than the standard crimp removal tools. Give it a go. I and others successfully use the drill bit method, especially for the large primers (in my case at least). But if the primers are then fitting too loosely, you are probably drilling too deeply.

You will find an inexpensive answer in a $10 Lyman Primer Pocket Reaming tool, which does the job pretty quick. Unscrew the head from the handle, chock it into your drill and less than 5 seconds later you're done with the case. (otherwise you do it by hand and it's a pain)

You should be able to find this tool at Cabelas, Bass Pro or hopefully, your local gun store that sells reloading supplies. There are many options but this is probably the least costly designed for the task.

Good luck.

Be safe.
 
Specialized tool vs drill bit or pocket knife

You can remove the "crimp" ridge from a primer pocket with a drill bit. Even a pocket knife. But the tools specifically made for the job (mentioned by MarkGlazer and 949ACSO) primer swaging/forming and cutting tools are made by several manufacturers and are more readily manipulated (think of how uniform you would like your primer pockets to be...a free-hand approach with a drill bit is less repeatable than a cutter guided by the cartridge base).

The good news is that you only have to do this once on any given cartridge.

Lost Sheep
 
Go with the Lyman primer pocket reamer. Once you do all the pockets you will have great brass that won't need the pockets reamed again.

I would like to thank all members for your help. maybe I can return favor.
Hope you all have a great 2016.:)
 
Those are crimped. I did a batch of those, and will never bother again. Uncrimped, used, commercial 9mm brass is incredibly cheap and plentiful.

I first tried the Lyman pocker reamer, and it still needed chamfering. I used the RCBS primer pocket swager, since I already had one, and even with it, the pocket must be chamfered after swaging, before you can seat the primer. I loaded a box of 50, and decided it was a good learning experience, but my time isn't worth the trouble with 9mm.
 
Re: post #12

Which is why the drill bit method can be better. Especially with the swaging tool, there will be shearing with some primers during seating. Proper use with the drill by applying a taper completely eliminates shearing.
 
OP meant 1.169" WCC are mil crimped. They are actually good brass once you remove the crimp. Drills, especially center drills, and pocket reamers are ok, but the best way is to swage them. Or a Dillon 1050 has a built in swager but it costs almost $2,000. So a better option is RCBS single stage press swager because the case is centered in the die. Once you deprime the mil brass, set the case on the swager pin and mash down the handle. I usually wait till I have a few hundred then run them all at once. The setup has to be right, run the die body all the way down to the cap with the handle fully down, then adjust the top pin to push the crank handle about 1" up. I have run thousands of these and all have primed correctly.
