Primer pocket crimp removal

[skruske]

I tried the RCBS PP swage & did not like the results. The primer pocket was still far too tight to consistently seat primers with both small and large primers.

Using my benchtop drill press, I then tried the Hornady primer pocket reamer, both large and small and got closer to what I liked but it wasn't perfect either. Hornady reamer was too long & did not cut away the ring in the case head. I even used a stone to take a little off the tip of the reamer. Still, it did not remove enough of the ring to allow smooth seating of a primer. These are the tools I use in the drill press with a stem added to the first three. Left to right Lyman deburring tool, Hornady small pocket reamer, Hornady large pocket reamer, RCBS chamfer/deburring tool, Lyman flash hole uniform tool.

After that I employed the Wile E. Coyote School of Case Preparation and mounted an RCBS chamfer/case mouth deburing tool in my bench top drill press.

I simply push the primer pocket into the spinning deburing tool & cut away just enough of the ring to enable primers to be seated.

The chamfer creates just enough of a "funnel" to allow the primer to be seated. It is not a nice radius edge like a factory RP .223 but it works well enough. As always use caution until you get a feel for it. It takes less than a second to make the cut into the ring. Don't use too much force, just a light push upward. DO NOT wear gloves using this technique as the material may get caught in the spinning chamfer tool.

Here are the results. WCC with the ring chamfered away vs RP factory radius.

I have done 1000's upon 1000's of mil crimp 5.56, 7.62x51 and 30-06 cases this way with mostly good results.

I have done the same way and works fine. Have never had a loose primer issue.

[Roundnoser]

Yup. That is the same way I do it for my 5.56 brass...but without the drill press.

Started like that, got the Lyman cutter, then the RCBS swagger and now the Dillon.

[Doc Highwall]

I started with the RCBS press mounted and now I use the Wilson when I have to.

I started out using a pockeet knife in the early 60's, later bought a Lyman with the wooden handle, then bought the Dillon swager and they all worked. I finally found a Forster reamer to fit my Forster case trimmer and that is what I am using now. All worked, it was just a matter of finding what I was more confortable using. james

I had a guy tell me that he used the chamfer tool, like you. I sissied out and bought a Dillon swager. I figured that if there was a way to over do it with the chamfer tool, I'd find it quick. Haven't gotten it set up yet. Most of the .223/5.56 brass I have access to is NATO brass and I have a HUGE pile of 9mm NATO to swage too.

[ROGER4314]

I started with that electric drill method, went to the RCBS press tool for single stage presses (didn't like that one), use the RCBS motorized prep tool on my NEW pistol brass and got the Dillon Swage tool for .223, 30-06 and .308 rifle rounds as I have a lot of Lake City once fired military brass. So far, I'm happy.

Sinclair makes a little tool that can be used with a little cordless bit driver that accepts those double-ended case neck neck bevel tools. It is so handy to use for small lot primer pocket crimp removal. Very quick to learn uniform usage too.

Being a life-long machinist/mechanic my first thought to remove the problem was a countersink. Plain old high speed steel sixty degree countersink that I have used for champhering/deburring holes. Having several on hand it was the first tool I picked up and tried; 100% success. In the last 25 years or so I must have removed thousands of primer pocket crimps with this simple tool (it can be used by hand, add a handle, or put in a drill, drill press, ot power screwdriver). http://www.mcmaster.com/#countersinks/=lipejr K.I.S.SS.!:-D

[W.R.Buchanan]

MDI: I'm with you.

I have several different ways to fix primer pockets. I use a countersink in a cordless drill and sit at the bench where it's comfortable.

The countersink method is definately the simplest, quickest, adn cheapest way to do it. :mrgreen:

I got the Lyman primer pocket reamer when I had a bunch of S&B 45ACP brass. Rather than throw it I sprang for the Lyman set (actually asked for it as a Christmas gift) and it does a good job on the military crimps, too.

[MOcaster]

I started off using a Lee chamfer/deburring tool to cut out the crimps. That got old really quick. I looked up different ways to remove crimps but didn't find a way that looked good to me. So being who I am, I looked around my shop for something. Then I remembered that my Lee press came with a primer seating arm. I put the shell holder in, added an FC 5.56 case, and pulled the lever. It swaged the crimp out perfectly. No more cramped fingers from cutting out crimps.

1/4" drill bit in a cordless drill...light press on the primer pocket and the swaged ring is gone. Investment...minimal as I already had the drill and the bit in the tool box...

[S. Galbraith]

I prefer the Dillon Super Swage. Yeah it costs $100, but the speed and small work space it takes up is worth it.

[dromia]

I use the Lyman deburing tool for removing crimps and The Lyman primer pocket uniformer for the pockets all turning on the Lyman Xpress Case Prep Centre. http://img.photobucket.com/albums/1003/adamsutherland/Smilies%20FB/FB%20UK%20Smilies%202/sSig_goodjob.gif

I do the same, I really do like the Lyman case prep......

[Lloyd Smale]

Ive tried about every method out there and bought a dillon swager and never looked back. Even if you think you wont use it enough to justify the cost, you can buy one, do all your brass and sell it when your done. You cant have mine though!!

[kostner]

Used the counter sink in a drill press for a while then finally took the plunge for a Dillon Super Swage for $112. There is a learnin curve to it and its taken a few sessions to get it right. But it is a Dillon product and does work after reading the directions a couple of time. Another fine tool I've bought is the Possum Hollow case trimmer at about $25 is just as good as my buddies WGT for $79. If $$ is of concern that give a look see on YOU Tube.

[David2011]

Kostner,

Glad I'm not the only one that thinks the Possum Hollow is about the same as the WFT. I have both and there just doesn't seem to be much difference. The IDEA of the bearing is nice but in practice one is just as big of a pain to adjust as the other and the bearing makes little difference to me. I think the WFT would be better with a decent carbide end mill. I think the carbide end mill would reduce or eliminate the need to chamfer inside/outside

I have had some seating issues even using the Dillon Super Swage, especially with older CCI primers. I was talking with Jimmy Mitchell, the 1911 smith, about it. He convinced me to try CCI primers; said they feed much better than some other brands in progressive presses. Sure enough, the newer CCIs in the dark blue package and later versions feed smooth as butter in my Dillon 650 in swaged pockets where some other brands cock sideways or crunch.

When I just HAVE to use other primers, a quick touch with a Hornady primer pocket reamer after swaging makes for an easy entry but doesn't enlarge the pocket.

Been there done that, moved on to a Dillon.
