Good question. Cheap/inexpensive or high volume production?
Preparing military brass for reloads
What is the best way to remove the primer crimp in military brass?

I have options? Right now, I can't get my hands on a ton of the brass at any price, so I guess I'll consider "cheap" if it works well. I have 500 cases (small rifle primers) of once-fired pick up brass and 95% is crimped.
Why does the military crimp primer holes anyway?
Thx...

500 pcs and maybee more?
get a crimp reamer.
most of the big names sell case prep tools. hand or automated.
I bought a kit that has reamers, proimer pocket uniformers, flash hole clean / ture, and ID / OD reamers for mouth from lyman.. think the kit was 50$ with a soft side case.
works great.
I later upgraded to their 5 head auto center.
was worth the money for me.
I came by lots of greek milsurp and plenty of 556 milsurp..

Use it in a trimmer for perfect depth control or chuck it in a cordless drill and go by feel and eyeball.

Military surplus brass primers are crimped to make the cartridges better able to withstand the rough and tumble wear and tear and weather of infantry life in the field.I have options?

Make sure the brass is boxer primed, not berden primed:
If it's berden primed you may break your depriming tool.
There are a few threads here about this; here's one

Military brass tends to be thicker than non-military brass so it's interior volume will be smaller. A general rule of thumb is to decrease the powder volume by @ 10% from regular cases.

If you have lots of brass to prep. I would go with the dillon myself.

Yeah it's $100 but it is fast consistent and easier on your arms.

I use this one. I've used it for both small and large primer pockets. I like it because its adjustable so you can set it for just the amount of removal and taper you want. I put it in my RCBS case prep center and hit it at the same time I debur and chamfer. http://www.midwayusa.com/product/25...er-straight-cone-military-crimp-remover-small
dillon primer pocket reamer/swage tool, it's the bees knees...
i just use the pointy end of my case mouth chamfer tool.
For cheap, you can use a 45 degree countersink from harbor freight -
It only requires a couple turns of the tool --
I prefer swaging the pocket, but others prefer reaming --
There is no best way, both are suitable --

For many many years I used one of these: http://www.midwayusa.com/product/389104/lee-chamfer-and-deburring-tool
I use the Lyman case prep center now: http://www.midwayusa.com/product/211733/lyman-case-prep-xpress-case-prep-center-110-volt
The Lyman really works great and takes about 1/10 the time that the Lee deburring tool did!!

I don't know if the long time reloaders will agree with this but what I did was I chucked my hand deburring tool to my cordless drill and just drilled out the crimp a very little bit. Too much and the shells bad. Very cheap method and very effective.
Their consistent inability to keep items in stock has made me order from Midway very few times. That they charge additional shipping fees when they get one more of your items in stock is insane.it's OOS
i checked midway.. lots of case prep tools are OOS as well.
I have never thought of that, but if it works, that's great!! How big of a chuck do you have on your drill? The deburring tools I have seen are too big for any drill I have!!I don't know if the long time reloaders will agree with this but what I did was I chucked my hand deburring tool to my cordless drill and just drilled out the crimp a very little bit.

hes talkin about chuckin the little guide on the outside chamfer end into the drill chuck George. I been doin it for years. Just spin it and touch the primer pocket to the chamfer tool real quick.
OK, I got you!!hes talkin about chuckin the little guide on the outside chamfer end into the drill chuck George. I been doin it for years. Just spin it and touch the primer pocket to the chamfer tool real quick.
Just like a couple of the other previous posts said,.....Dillon, the same people that brought you the blue press. This thing is slick to operate and fast, I can do about 100 an hour on it. The only minor down side to it is it locates off the inside web, variances in web thickness and flash hole burrs can have an effect on the depth and radius of the swage. Aside from that this thing belongs on the same list as sliced bread and canned beer.
