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..

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.

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.

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 --

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.

it's OOS

i checked midway.. lots of case prep tools are OOS as well.
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.

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!!

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.
