I found the RCBS pocket swager die . This was on backorder from Midway. Are there any other methods?
 
I use a tool similar to jr45 by RCBS. When I started reloading (a long time ago) I used a pocket knife.
 
I setup the RCBS pocket swager die setup on a spare press (RCBS Partner Plus) and that is what I used to swage my military crimped stuff.

And I have a LOT of military decrimping I have to do. About 2000 308 and 2000 223. :(

I am thinking about buying the Dillon Super Swage though, it looks even easier and niftier than the RCBS tool that I use.
 
I get a few military crimped brass with range pickups. After punching out the primer I usually just use the small end of the chamfering tool to remove the crimp ring. You can also use a pocket knife if you have an old cheap one your don't care about the blade.

If I was to get a batch of military brass with 100's of cases to remove the crimp from then the RCBS or other specialized tool would be the way to go.
 
I have a pocket knife, as thrifty as I am, I wonder that I didn't think of that. I tend to complicate reloading.
 
Many...

I am not a carpenter, BUT there are counter sinks for the taper on flat headed screws. One is best for large rifle and the other for small rifle. Don't recall the numbers--you have to find and examine the chart. You buy the one you need, chuck it into drill or electric screw driver, touch the primer pocket on the cutting surfaces, DONE!

I did my first with a pocket knife. Got a bit enthusiastic. When I finished the primer would drop right out... One pass around with a sharp knife blade and the crimp is gone. Many many case neck reamers will do the job. Some don't go in far enough. I have done a number with the Lee unit. Fingers do get tired. This was before that wooden ball was available.

The classy way is to use a primer pocket swager. I have the RCBS. Great unit, BUT only works in my rockchucker. The other presses I have don't have adequate clearances. I think it is the CH4d.com unit that sits on top of the press, any press, and the much longer swage rod comes up thru a die... bit faster, does a good job. Costs a bit less. Your call. Luck.
 
I have the RCBS swager. Works fine but really slow.

I have the Lyman primer pocket kit which comes with a range of cleaning and pocket chamfering tools and has it's own little pedestal crank. Works well and is reasonably quick.

For small quantities of boxer primed cases a chamfering tool is all you need. The one that works best is the $2.50 Lee one.

I have modified mine by cutting and grinding the tip off so even Berdan primed cases can be easily decrimped. The angle of the cutting edges are just right and it has a very aggressive cut so it makes quick work of it.

The aggressive cutting action is actually detrimental for its original purpose of tidying up case mouths but really helps for primer pockets.
 
Dillon Super Swage 600.

Picked mine up at auction for $35 about a year ago.

If you are not in a hurry, just keep your eyes open and cash on hand.
 
relisted

E-bay pulled the listing because the title said that it was similar to the RCBS swager. I revised the title and relisted it.
 
I take the RCBS deburring tool, lock it in a small vise, sort out crimped brass, insert them in a drill, spin a couple of times and its over. You get a feel for it after a few thousand times. Be sure you insert brass all the way into the drill, the chuck can crush the case walls if its too far down.
 
Has anyone tried this CH swager?

I have heard of problems with deformed rims.

The CH doesn't support the case from the inside like everyones elses swager tools.

All the force is applied to the rim by the shell holder.

Nope, still not showing.

Can you provide a working link to the new auction? I want to check it out.
 
Super Swage on flea-bay. for $91 right now.

Or spend a couple of bucks more and buy it new from Dillon. I find that you can usually buy from a Dillon Distributor and save a bunch on shipping. I find their shipping a little on the high side. Just my .02
 
I have taken the Lee Chamfer tool, and just turned it a few times in the primer pocket, and the primer just goes right in like it should.

I don't know if this is the method of choice, but it has worked for me.
 
Call me crazy but I often find about 100 spent rounds of PMC 223 at the range. So to speed up the proceess of removing the military crimp I put a lee swage tool in a bench vise and put the brass into a cordless drill chuck with the drill on the lowest speed setting. I then apply the brass to the swage tool with no pressure and count to 3 then i remove the brass from the chuck of the drill and the new primers load smoothly.
