Coke Bottling 9mm cases


December 21, 2006, 11:16 AM
I have bit of a problem with coke bottling of my resized 9mm cases. As they go through the sizing process it seems like brass gets pushed down towards he extractor groove.

I had the sizing die set to just contact the shell plate. (Dillon Carbide 9mm dies on a Dillon 550 press.) These loads feed and function fine in my P95, but occasionally one will get stuck in the chamber of the Glock preventing it from fully going into battery.

I have tried to raise the sizing die a bit to see if this would help, but that just kept any of the cased from fitting the glock chamber. I have not yet determined if only cased fired from the P95 suffer this effect or not.

Have any of you guys seen or experienced this before? Know how to best prevent this from happening.

Just for completeness, brass is Winchester or S&B, happens with both. Glock is is both my and my wife's G26s. Any help would be much appreciated, thanks.

Yuou want your sizing die as close to the shell plate as possible. I think what is happening is you are not rezing the brass to the bottom of the case. With my 550 I raise the ram fully and screw down the sizing die until it toouches the shellplate.

Take Care

ARP,I love Dillon reloading dies,most of my dies are from Dillon.But,their 9mm dies do not iron out the Guppy belly.The 9mm is coke bottle shaped anyway,with Glocks that do not support the case as well this becomes more pronounced.
Lee carbide dies do a good job of resizing 9mm.EGW sells a version of this die,I don't know if its really different but Lee makes it for them.Many folks are pleased with the EGW die.
I don't know why Dillon has not addressed this issue,they normally listen to their customer base.

Thanks for the help Rodinal220, could you please elaborate on the EGW? It that a company or a brand? Still just a bit confused, thanks for the help.

The EGW die is a Lee sizing die that is .001" under normal size and made so that it will size a little lower on the case. The gives you more case tension and irons out ANY bulges on the brass. More case tension promotes more consistent ignition, prevents setback, and generally makes better ammunition. One 'problem' though is that with the case .001" less than normal seating bullets can be tough, especially if the seating stem doesn't fit the bullet profile well.

Team the EGW sizing die with a Redding Competition Seating Die, and whatever crimping die you have that is set properly and you will have the best die set money can buy in my opinion. Consistent, reliable and accurate reloads are the result of this die set.

Common reloading problem, many of the new generation handguns have oversized chambers and no reloading die can get low enough to eliminate the "magnum belt" caused by the oversized chamber and nonexistant chamber support.
Some commercial reloaders use a newer machine to roll out the bulge before the resizing, it's pricy tho.

Had the same problem, Glock 9mm and Dillon dies. Hard to believe and accept, but a Lee full-length taper crimp die fixed the Dillon problem!!

i used to have the same problem I used a steel 7.62x25 size die worked the nuts as the steel die reduced the case dia rather than carbide which reforms the brass making it look like a mini belted magnum

Dillon dies are chamfered more at the entrance to allow the cases to feed easier into the die without bumping the case mouth and stopping the ram. If your pistol doesn't over bulge the case they are absolutely wonderful in aiding the progressive press speed of production. If your gun does bulge the case due to over size chamber, you'll need the Lee or EGW die to return the case to factory specs. Now...if you only load for the ONE pistol, then either set will work. I do really like the Lee factory crimp die...makes sure that all the loads fit!
