Since I began using a Glock 21 in competition I have had more and more cases that will not drop into the case gauge after loading. I am using a Dillon 650 & Dillon dies. My sizing die is touching the shell plate. If I draw a line with a marker on the case and run it through the sizer, a little more than 3/16ths of an inch is unsized above the rim. The bulge measures .475, and will drop into the barrel chamber on the Glock. What I need is something like that GRX die from Redding that you push the brass clear through, but it is not offered. Does anyone have any suggestions. The Dillon is supposed to be a full-length sizing die. I am considering a fully supported chamber aftermarket barrel as one fix.

I had the same trouble with Glock 9mm and 40 S&W cases....lots of rejects even with the "Full Length Sizing" in the 650 press set up. Lots of searching/seeking/research/long distance phone calls etc.

Finally learned of Lee's Factory Crimp Die installed at station FIVE. Works perfect now with no rejects ever. Costs about $20. I had to install the lock nut under the mounting plate. Thought it might be awkward but again, no problem.

Some argument/disagreement from those that have academic issues with FL sizing of loaded/primed case. It was hard to ignore their facility at creating plausible concern.

Tens of thousands of rounds now with no unpleasant incidents.

Let us know how it works for YOU.

Suitable disclaimers/cautions/denials in effect. It's what *I* do to solve *MY* brass problem...."you didn't hear it from me".....
 
What is the load?

Since I began using a Glock 21 in competition



I for one would like to know the load you are shooting out of the Glock. I have loaded many, many rounds for mine and my son's Glock 21 and have never had a problem with bulging cases.

Now, most of our loads are target type of loads, granted. But still, you must be running some real hot rounds or you are using extremely thin brass. It wouldn't happen to be "RP" brass, would it?

I can tell you the loads we have run and maybe that will help. 4.7gr Bullseye behind any 230gr Plated bullet; 5.2gr or 5.3gr AA#2 under the same bullet. There are also some 200gr LSWC that we ran in both of ours with an aftermarket barrel.

I use the setup M657 uses too. A LFCD in station 5 of an XL650. I have used a Dillon Square Deal B to load for both of those Glock 21's too and never had a problem either.
 
Dillon sizing dies are known to have a generous mouth chamfer specifically allow the cases to align with the die in progressive presses. Trouble is you loose the ability to size cases where it counts. I use RCBS dies and occasionally cases don't align but they are sufficiently sized. Other "standard" sizing dies will probably work as well. +1 for the Lee FCD.
 
If you're really serious, and do enough shooting to justify it, Magma makes the CaseMaster Jr. specifically for solving this problem. Here is the link: Case Master JR Rimless Case Sizer

I have one, along with the dies for doing cases in the 9mm family, 10mm family and .45 acp family of cases. I run all my .45 acp brass and .400 Cor-Bon brass through the .45 die. All my 357 Sig, 9x25 Dillon, .40 S&W and 10mm brass is run through the 10mm die. My 9x19, 9x21 and 9x23 brass is run through the 9mm die.

This machine is set up on an arbor press and pushes the entire case all the way through the die, sizing the whole case, including the rim, which means it can only be used for rimless cases.

I wouldn't be without this machine, but I load for 29 different calibers and have loaded over 750,000 rounds of ammunition over the years. This may be an extreme cure for your problem, but it does work for me.

Hope this helps.

Yes, it is R-P brass. Previously it was 5.7gr W231, and a 230gr Hornady HAP, current it is 5.5gr Universal Clays with same. That puts it in the 800fps range. Never had the problem until the Glock came into the mix. Glock barrel chambers are loose, and unsupported under the feedramp area. I've spent some time and effort finding the problem. The Dillon die is pretty generous at the start, and I have considered machining it down in overall height and screwing it in deeper. I've also thought about making a push through die like the G-rx from Redding, by cutting the top off of a sizing die and pushing it through on my Lee single stage. I have to load to 750fps to make power factor with a 230gr bullet, 800fps gives me a margin.

Reloader Fred, that case resizer is sort of what I'm looking for. Redding currently does it cheaper, but only for 40's grx push thru die.html It is really just a sizing with the top and decapping parts removed. My single stage press could be the fixture. Redding says not enough demand for anything but 40's.
 
sar4937,

Magma uses a Dillon carbide sizing die, and polishes it out so it will size the whole case, which means it's a little larger in diameter than a standard sizing die. I run my brass through the Case Master Jr., and then size and deprime it. You want to lube the cases lightly prior to running through the Case Master Jr., and that makes them size even easier through a carbide sizing die. The cases are loaded into tubes, which you supply, and you can run the cases through the machine as fast as you can work the manual slide and pull the handle. It's a good workout when you do a couple thousand cases in one setting, but it sure makes the brass come out uniform.

It could be done on a regular single stage press, if you had a sizing die that was of the proper diameter. I'm sure Magma would sell you the die only, if you asked them. You would have to make a push rod for the press ram, but I think the Lee push through bullet sizing ram that fits on the press ram would probably work. You would need the ram that would fit inside the case, which would probably be a .357 ram, since you really just need something the diameter of the inside the case, where the web is flat to push on.

The Case Master Jr. pushes the entire case through the top of the die and out the bottom. In a single stage press that would be reversed, but the die could be screwed into the top of the press from the bottom and work the same way, but push up through the die instead. The mouth of the die is tapered for feeding the case, but the bottom isn't, which is why I would mount the die upside down on the single stage press.

Just be sure to lube the cases with some spray lube to reduce friction. When you're pushing the entire case through the die, the solid portion of the case doesn't compress.

While I was typing this, I thought about the Lee Factory Crimp Die. I believe if you took the guts out of the die, and pushed the case all the way through, that would solve your problem and be a lot cheaper. You would only have the carbide sizing ring, which is what you really need for this. You might give that some thought, too.

Hope this helps.

Just a thought.

sar,
If it were me, the quickest fix would be to change brass. Go to a range and ask to go through some of their scrap stuff. See if you can find some Fiocchi brass. This is quite a bit thicker but will resist the case expansion much better.

RP brass is known to be much thinner than most. This could be exacerbating your problem. If you can't find any, send me a PM. Maybe I can help.
 
I have just under 20K rounds of once fired R-P brass accumulated over the last few years. I started with the first batch of 500 and have reloaded this batch over 50 times, only a few cases have began to get rough at the casemouth. I heard alot of bad things about R-P, but have had exceptional luck so far. The only range with brass in the area sells it's brass to Ultramax, our outdoor range only has 2 kinds of brass, stuff no one wants, and the stuff you personally bring to shoot. I ordered an undersized die from EGW, and I'm going to try that. If that still doesn't work it will be made into a push-through die. That Glock will fire the bulged brass just fine, it's my other 45's that won't chamber them.
 
For those with lots of brass and lots of case, a ROLL sizer is the tool to cure Glock bulge. The machine rolls the cases down to the original OD and does so in volume.

NOT cheap, however.


The real solution, of course, is to shoot a real gun; not a plastic fantastic with an unsupported chamber caused by cramming too large a cartridge into too small a frame.

Sold my Glock for a 1911 and never looked back.
 
I use a Lee undercut sizing die for any 40s that I load. Neither the Dillon die in my 550b or my RCBS dies will get the case sized enough to fit all the way in the case gage although they will drop right in the barrel of my M&P with no problem. So if I want them to fit in the case gage I use the undercut die and if I am happy that they drop right into my barrel when checked after regular sizing I just use the Dillon dies.
 
Bulged Glock cases

Darn, Amici beat me to it . I was js tgoing to say that you could trade the glock on real gun.
 
Well now, this is all very interesting. I own two Glock 21s and three S&W 625s and have done quite a lot of shooting with both platforms. Both of my 21s were purchased used, and the first one came with a Bar-Sto barrel which functions perfectly in both of them. My 625s are all -4 models. The vast majority of my Glock shooting has been with the Bar-Sto barrel and cast bullets. The little bit of shooting I have done with my Glock barrels has been to work up and test heavy handloads for reliability and case head expansion. I am quite satisfied with my Glock barrels and have no qualms with shooting heavy handloads through them. Whatever the Glock shoots is resized with an RCBS carbide sizer die in my 650 and I have NEVER had issues with "Glocked" brass in any of my 625s. In fact, I am a notorious scavenger and I will pick up every single piece of .45 ACP brass I find on the range, and the only problem I've ever had is A-Merc brass that would not fit into the chamber of the Bar-Sto barrel. I throw out all my A-Merc brass and there is no need to chamber check any of my loaded rounds.

As for the 1911 platform, I would never trade a Glock 21 for ANY 1911 type pistol, no matter whose name is on it or how much it cost. I am eternally grateful to Colt for making me such a big fan of revolvers in general, and the 625 in particular.

You gotta shoot one well in order to appreciate them.

I never would have owned a piece of "Tactical Tupperware" either until I shot one. I don't shoot a Glock as well in competition as I do a 1911 BUT it sure is comforting to have something that carries twice as many rounds and doesn't have a safety to "snick" off coming out of the holster for self defense.

In my world, both firearms have their place. The 45ACP is a great self defense round and an awesome target round. I'm thankful for both platforms to shoot it out of.

Now my youngest son is another story altogether. He shoots his Glock 21 like it is an extension of his arm.
 
I have 6 1911's and 4 Sig-Sauer's, and 2 H&K's I have used in the past. I dislike plastic guns, but they dominate USPSA Limited/ Limited 10 class right now. I also don't worry about rain and snow, because it's a tool not a gun.
 
I measured chambers in seven different 45ACP barrels

I measured chambers in seven different 45ACP barrels (Smith&Wesson, Springfield, Glock, Colt, and Bar-Sto). The dimensional ranges were all comparable. The Glock OEM barrel dimensionally did not have the largest chamber. As for full support Bar-Sto (G21) by virtue of the feed ramp angle had the least unexposed case area. The Glock OEM barrel in that respect was no better or worse than throated 1911 style barrels.

I do not segregate cases one from the other dependent on the pistol used. For a case gauge a barrel chamber is employed. The die set employed is RCBS vintage 1984 in my RL550B. I also have two SDB units one set up for large primer and the other small primer. I’ve loaded 45ACP with the standard Dillon die inserts of the SDB series and have had no problems.

As for 9mm Luger I’ve experienced no problems between cases fired in a Glock 17 or an S&W MP9

As for the S&W 40 can’t speak to that don’t own that chambering.

People love to bash the Glock. In my personal experience I’ve only owned one pistol that can out Glock the Glock in reliability and that’s the S&W 4506. While I like 1911 pistols not all feed flawlessly all the time with all bullet configurations. That’s my experience in forty plus years of usage. If I were to use a 1911 for personal self protection it would be 230Gr-FMJ ball
 
Anyone reading about my desire for a push-through dies should know (I should have realized it as well) that there is a slight rim to the 45acp case, and a taper to the 9mm case that prevents a cheap push-through solution. The Glock barrel bulges all calibers. The Dillon die has a generous portion at the bottom to encourage alignment in their progressive presses, and from time to time some brass does not line up and jams the press. Some have told me good luck using an undersized Lee die in the Dillon for this reason. So my plan is now to decap and size & inspect my cases in my Lee classic, then run them through the progressive to load.
 
The Glock barrel bulges all calibers. .

That’s not so from my experience. All fired cases expand to an extent. Properly resized cases are not problematic. If this were not true then why can I exchange cases between seven different barrels with no chambering problems? I’m not shooting light target loads either (5.7Grs W231 230Gr FMJ).

I can also interchange reloaded cases between a Glock G17 and S&W MP9 with out issues.

As for the S&W 40 you’ll get no argument from me on case bulge.
