military primer crimp

edited December 2009 in Perry Shooter Competition Shooting and Reloading Forum
what's the best way to get rid of a military primer pocket crimp? I don't have a fancy reamer/de-crimper and I don't want to have to spend the money on one. Is there a "backyard" way to do it? I have the Lee single stage kit with accessories and I've tried the chamfer tool on some mil brass but it didn't seem to work. Any other suggestions?

    A small pocket knife with a sharp blade and a little practice is the cheapest.

    You can use the reamer on a Dremel.

    +1 on DCS post. I'm about as cheap as anyone, but there's just a point where it's less expensive to buy the tool. The hand version works well and is very inexpensive. I honed down old screwdrivers, used the chamfer tool, used an exacto knife (only cut myself a few hundred times), and in the end a few bucks just made life so much better.

    Good luck

    If you don't want to get a swager, at least get one of the ready made reamers. You will get more even cuts and are not as likely to ruin cases bu cutting too much. I got some cases a while back that were supposed to be reamed and ready to prime. I found later that the guy used a phillips bit in a drill to "ream" the crimp. Totally inconsistant with some not enough and some 3 times too much. Some cases completely buggered. For less than $10 you can do the job kind of right.

    Less than $10? (all the others I've seen are much more expensive than that) now you're talking my language. point me in the right direction.

    Advise will cost you. [}:)] oh wait, you already used that one. As previously stated, RCBS has a swagger tool that works well. I use it with no issues.

    On the realistic side; the RCBS primer pocket swaging kit is the only way to go. You can adjust it to remove the crimp without damage to the brass. It is the best way to remove the crimp from large amounts of brass. I've had mine for 25 years or so.

    On the cheap side; take a block of aluminum drill a hole in to match the shaft size of a old motor from a dryer or furnace. Attach it to the motor with two set screws. Take a grinder and put a flat spot 1/4 inch long in the middle of the RCBS deburring tool. Drill the block big enough to accept the deburring tool. Put the deburring tool into the holder and lock it in place using a set screw into the flat spot you ground.

    You now have a power de-crimper, time saver, no money spent machine. Your fingers are going to get tired of pushing the cases into the tool and once an a while you are going to trim a nail back, but it works flawlessly and fast. I had a 1/2 HP motor from a machine that spun at 3750 RPM, it cleaned the crimp out in a go-fast-hurry. [:D] If you turn the deburring tool around you can also clean up the case mouth. If you happen to miss the center with the case, the spinning legs of the deburring tool will trim your nail back pretty near to the first knuckle, BTDT [:0]

    I retired that gizmo as soon as I got the RCBS pocket swager.

    Take a Lyman reamer and pull the pin and take the reamer and chuck it in a power screw driver or drill and you have a power reamer [;)]

    I use the RCBS pocket reamer I've had for 30+ years.
    It will chuck up in a drill if you stick the drill jaws between the legs on the outside reamer and chuck on the rod in the middle. Works great and takes about 3 seconds per piece.

    I just grab the chamfer tool in my right hand and the case in my left hand and twist. Cost me nothing, and the crimp's as gone as yesterday. Takes about an hour to do 200 7.62x51.
