Crimped primer pocket

[Gibill]

Have some 223 military brass that has crimped pocket.......what is the best tool to lose that crimp for easier priming?

I've used a countersink drill bit with some success. I got a Lyman ream/clean accessory set from Sinclair/Brownellsthat has produced good results.

[Gibill]

Did the countersink bit reach the flash hole and harm it? How much was the lynam kit?

[BlackEagle]

Current price on the website is $13.95 for the Lyman kit.

You don't get the handle with the kit. Just the black bits shown in the picture.

The countersink was a little awkward--it cuts at an angle, not straight in, but it was something I saw somewhere, maybe on this forum.

I bought myself one of the Lyman case prep centers for Christmas last year. It sure makes quick work of de-crimping a .223 primer pocket. http://www.grafs.com/retail/catalog/...roductId/22831

Another way to go, which is way cheaper but a lot more work is the little Lee chamfer/deburring tool, I used these for probably 30 years before I bought the Lyman: http://www.grafs.com/catalog/product.../7581/inline/1

the tip end of your chamfer tool works great. and no need to buy another tool. Chances are you already have one anyway.

This is what I have been using as per advised by a fellow reloader that reloads maybe 6000 .223 rounds a month. (many are for private sells, but most are for the local PD)

Swagging the primer pocket gives you more of a chance of reloading the .223 brass more times. If you are reaming the primer pocket .....chances are the pocket will get too lose for future primers.

I just did a bunch of 9mm brass w/crimped primers. I use a 60 degree high speed steel countersink. The one I have has a hex shaft and fits in my drill/screwdriver, and I did mebbe 100 in about 15 minutes or less. My countersink cost less than $10.00 and I've been using it for several years to knock out the crimp on military primer pockets...

not wanting to ruin any brass.. I flipped for the lyman tool kit that has manual cleaners and reamers for large and small primers, plus PP trueing kits, plus a flash hole cleaner.

they worked so good i flipped for the automatic model with 5 spinning heads....

best way i know to get rid of a crimp, clean and true a pocket, and no chance to damage it with a drill bit...

You won't cut deep enough into the brass to really shorten its life from loose pockets.

Nope. Most of the crimps are just a few thousandths deep and a 60 degree break on the corner of the pocket, deep enough to remove the crimp, has no effect on brass life.

I've had a Dillon Primer Pocket Swage for years, and feel that it is the best product on the market for removing the primer pocket crimps. Mine came with .22 and .30 caliber spuds, and it locates from these and the web inside the case. Consistant results from case to case, primers feed in like commercial cases aftrer the process. It is adjustable to account for minor differences in web thickness' from brass lot to lot variations. For it's indended purpose, I wouldn't trade for anything else.
