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".....

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.

Fred

Once again!
NO END to the neat stuff you learn about in this joint!

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.

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.

Dave Sinko

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 (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.

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.

Concerning the .40 S&W.

I am currently shooting about 1000 rd a month throught my Glock 35. I am using range pick-up brass, Local PD, Border patrol, Forest Service, Private party, Etc left overs.

I size all the range pick up brass in a EGW U-die. this is an undersize sizing/decapping die made by Lee for EGW, that removes the bulge.

This die is used in a RCBS single stage press.

By using this die I can inspect each case, after tumbling and remove the stuck rocks, hidden 9mm cases inside the .40 S&W cases, hard dirt, Etc before loading them on my Dillon 650 with Dillon dies.

Yes this add an extra step, but it eliminates any .40 S&W bulged cases and also removes any other problems that would cause my 650 to jam because of debris left in the cases.

YMMV but it works for me.

My HK45 and various 1911's will not chamber my reloads that have been through my Glock 21. As I stated earlier the Dillon die does not fully size the brass to above the rim area. When I get my die from EGW, I will find out if it cures my problems. I began drawing a stripe down the side of the brass before sizing on the Dillon. My problem area starts at the point that the die doe not disturb the stripe. If I drop the brass into the Glock barrel, that area coincides with the feedramp of the Glock. I shoot 250 rounds a week, case gauge and measure every round, and my problem started with this gun. My Glock chamber measures .475, but it is possible for the brass to expand beyond that at the feedramp. The Glock has about 4000 rounds through it. My loads are not hot loads. And if the R-P brass was really that weak, it has given very good service in the HK45 I previously shot. I would prefer to shoot my 1911's, but this Jan & Feb our matches were near zero and in the snow a few times. The full rail of the 1911 and tight clearances don't offer reliable service at those temps, or at least not for me. Where do you suggest I look for the problem at?

For your 1911's to function in cold weather, I would change to a lube that works when it's that cold. I've switched to Machine Gunner's Lube from Sprinco. You can find it at sprinco.com. It takes very little and works in all kinds of weather and when dirty.

Hope this helps.

Fred

Take your sizing die and grind or turn off the first 1/16 of an inch. Your die is probably tapered at the bottom and is not sizing all the way down. Had to do this to load .40 brass that went thru a Glock

I thought the thread had died, so I did not post my solution. I purchased an undersized Lee die from EGW. I installed it in my Lee Classic press and run all my brass through it after tumbling. This does several things, it eliminates forty and nine brass from the mix, it forces me to look at my brass and allows me to cull any bad cases, it decaps the brass which makes my Dillon run really slick, and it fixed the problem. I was warned that if I machined the die I would run into brass feeding problems with the Dillon press, and that the Dillon die has a more generous starting taper for this reason. I was amazed how many shooters told me that 45's were exempt from this problem.

I’m glad that you were able to resolve your problem.

This past Sunday I fired a Colt 1911 and a Glock G21. The same load was used in both pistols 230Gr TC cast – 5.5Grs of W231 – WLP & mixed head stamp cases. The chamber maximum diameter for the Colt OEM barrel was (.001) inch larger than the Glock OEM barrel chamber. Measuring the cases for maximum diameter after firing on average there was a difference between the Colt and Glock cases of (.001/.0015) inch in diameter.

My dies are RCBS carbide set dated 1984

With this die set I’ve never experienced a problem of chambering between (6) different pistols chambered in 45ACP from (4) different manufactures.That’s my experience.

My 1911's are two Wilson's Supergrades and a Kimber Supermatch. My H&K will not reliably chamber these rounds either. My problems all began when I made the switch to a Glock 21 in Limited Ten. Prior to that all my reloads worked in all my guns without exception. The measurement you can't take is how much expansion you get in the feedramp cutout, and as you reload and refire your brass begins to bulge all the way around. The Dillon die will not remove it. I'm happy for your good fortune. But I didn't dream up this problem. I have a stock barrel, but would like to switch to lead. I'm told that a Lone Wolf barrel is so tight that you must have it reamed out if you reload. And the leade is so short that the bullet engages the rifling. After the Area 3 Match is out of the way I will upgrade. I know this sound like odd stuff to non-Glock folks. Most of my guns are S&W.

I am using Storm Lake barrels in my all my Glocks to shoot lead bullets.

These are drop in barrels and All four of mine have not required any chamber modification, The rounds are loaded to SAMI specs OAL.

For buldged 45 acp brass, bought a lyman carbide sizing die, and hammered thin "ledge" inward on the bottom. Filed and stoned it smooth Combined with a shaved shellholder, the 45 acp gets sized almost to the bottom. The die lasted about 5 years. Do my reloading on a single stage, ther may be problems with this on a progressive. Perhaps it doesn't need to be done every time?

This was done because had a tighter cut chamber on one 45 acp semi-auto that hung up on multiple fired and sized range brass. Most 45 acp brass fired and sized enough times "shrinks" in length. The bottom portion of the brass "swells".

The same technique was used for glock buldged 40 s&w.

I use any brass I can find to reload for my SA 1911, Glock 30 and Glock 21, a lot of it is fired from Glocks when I get it.
I use a Lee Turret press and the Lee dies and everything feeds great in all the fore mentioned guns.I think part of the problem is some dies do not take all the case mouth bell out on the final crimp step as well as the Lee dies do.

A Lee Factory Crimp Die will solve your problem.

Groo here
New barrel for glock that supports the case and is safe with lead...

I use a Lee Factory Crimp die on ALL of my pistol and revolver calibers. I load on a Dillon 550B and use dies from all of the major manufacturers.

Just add a Lee FCD to your Dillon and I would think your troubles are over.

I cast ALL of my own bullets and in the .45 ACP size to .452" and with the Lee FCD have NO problems chambering in several 1911's and two 625's.

That will also be the most inexpensive answer to your problem.

Assuming the worst (that it may not totally solve the "Glock" problem) then you are only out $20.00 or so. THEN, you can try sizing your cases separately in a single stage press. Frankly, I sincerely believe that the Lee FCD will solve your problems.

Let us know after you get the FCD - may help some other poor soul with the same or similar problem...

Dale53

+1 on Lee FCDs. I reload for Glocks with no problems using them.
