Default Bulged Brass?

Has anyone seen the new AUTO DEBULGE 40 that restores brass that has bulges in them?

Why would anyone want to use damaged, weaken, stretched cases again ?

Here's your sign.

That is about the worst idea since checking your gasoline level with the light from a Bic lighter. I hope its a joke

Im sure it works great. I would recommend that if you do this do not reuse the brass in another pistol that will bulge the cases. Like a stock glock barrel.

Shot a Glock rental at the local gun range recently. It was a 9mm, not sure of model number but all the brass came out severely bulged. I questioned why since I had no previous experience with this gun. I can't imagine being able to reload the brass from that gun. De-bulging, if it were even possible, would weaken the brass to the point of being dangerous and also stretched. Never was a Glock fan and never will be.

I have reloaded lots of bulged 40 brass. I don't shoot it in any gun that will bulge it again and I don't hot rod my reloads. Brass is malleable and shooting debulged brass in a fully supported chamber is pretty safe in my opinion. If you don't think so then just recycle it. If it was that dangerous then lee wouldn't sell a die to fix it.

Not trying to start an argument this is just my .02 cents

Happy Reloading!

If it was truely that dangerous to reuse Glock fired brass, wouldn't Glock have something to say about this? Jes a question as I don't have a Glock nor a .40 S&W, and my needs are covered with 45 ACP and 9mm...

No, gun manufacturers don't care about used brass. They forbid the use of reloads anyway. Once factory ammo is fired, it's done it's job, as far as they're concerned.

Stock Glock bbls do NOT bulge brass when loaded to saami spec. Where the issue comes from is guys loading beyond that or even ammo manuf loading beyond saami spec. Bulged brass is no longer safe to use for full pressure loads IMO, it's structural integrity has been compromised. Brass is ductile but once it goes beyond a certain point, you get stress fractures in the alloy.
A very slight swelling, as in oversized Glock chambers, can be resized but bulges, nope, toss em. The idea that it is safe because an opportunist sells a product to "fix" it is laughable. The "bulge buster" die is NOT designed to be able to resize brass that has stretched or bulged beyond normal sizing but to correct the lack of full sizing that some dies produce. Generally those dies setup for progressive presses can leave the last 0.005" or so unsized. This may or may not be an issue, depends on how tight the chamber is.

Yes what Fred J said. It's for normal sizing of the part the normal dies don't get to regularly. It's meant to make the rounds chamber smoothly, not to repair brass that is structurally shot. I shoot a lot of 40 never had a problem.

I use range pickups for all my service caliber brass. I shoot 40s in my XDM 5.25 which has a tighter chamber than a Glock. I use a lot of Glock brass & it sizes & shoots fine just running it thru my Dillon dies. I do have a Redding pass thru for my 10mm, but only use it if I get the slightly enlarged case from my Glock chamber & that is pretty rare. Just stick to saami pressure loads, the GLock chambers are fine.

Yes there is a particular bulge I have seen on some range brass that looks like a big smiley face that runs from the web up the side of the case. I don't blame that on any particular firearm, but I just recycle those. I have a pass through die also, but haven't had to use it much. I shoot mostly mid range stuff (well within SAAMI) so even my 40 brass seems to hold up quite well. Neither my Shield or my P226 appears to beat the brass up with my loadings.

I have used this device on a large batch of once fired "glocked" range brass I got from a sheriffs department practice session at our range. It wasn't badly bulged but enough that it didn't want to go through my normal Lee carbide sizer smoothly. I was just getting my first 40 (M&P Pro) so it was hard to say no to the source. This device worked great and processed the brass quickly. The resulting debulged brass has since been reloaded multiple times at target velocity pressures without sign of deterioration.

As I recall, my research into the phenomenon turned up that it was reportedly isolated to only early model Glock barrels (only). I can't verify this as I 've only owned two Glocks. Both had aftermarket barrels better suited to shooting my cast lead target loads .

Uh, no they don't. You enlarge a case enough in a rifle chamber to bulge it, the primer pocket is usually gone. Guys, it's a *******g piece if brass, toss it & get more, or how about load to the book & never see such an event. Truly bulged brass is not safe to reload. You may get away with it, but doesn't mean it's safe to do. I sometimes drive w/o my seatbelt, so far so good, but it isn't really safe to do.
Glocks have more generous chambers than other guns, but the cases fired in them will not be bulged UNLESS the ammo is loaded beyond safe SAAMI specs. I've probably picked up 5k rds of 40 brass alone over the last year from LE training ranges. None, not a single piece has shown a bulge at the chamber area. The vast majority of that is glock brass.

Default Brass Work Hardening

All fired cartridge brass is "bulged" to some extent. There's nothing wrong with re-sizing moderately bulged brass one time. Brass becomes progressively work hardened and embrittled with repeated strain deformations. The moderate expansions and contractions that go on in repeated reloading cycles are no big deal until the number of cycles, the resultant strain hardening and fatigue gets excessive. Normally a split neck or loose primer pocket announces the end of a case's life. If it were unsafe to resize a bulge one time, nobody would get away with forming brass to change calibers. I make hard to find 300 H&H out of anything I can lay my hands on, but use the formed cases judiciously. The reverse bulging to cold form a 375 H&H or 300 Weatherby to 300 H&H is considerable, but works well, and is far more severe than a bulged, straight wall pistol round. Gotta use a little judgment, as well. Reloading the typical 30,000 psi, or lower, pistol round is pretty safe compared to 50,000 psi + rifle rounds, and the consequences of a separated cartridge head are not as catastrophic.

For what it's worth, there was an interesting thread on the Glock Forum. I believe it was in "The 10 Ring" sub-forum. I fellow over there took some "Glocked" 10mm brass and ran it thru one of the various pass through type sizing dies. He then tested it to see if it would chamber in a couple of 10mm pistols, which it did without issue. He then sectioned a few of these cases thru the area of the repaired bulge and compared the cases to some resized sectioned cases which were not bulged. The areas where a bulge was repaired all displayed noticeably thinned case walls compared to the undamaged resized cases. Bases on this, I would never trust a bulged case that was run thru a pass thru die-especially a 10mm or .40 S&W case. It's true that brass is malleable. However, from the photos, it was pretty obvious that the brass did not evenly migrate back and restore the bulge in the case walls to their original thickness. I think there have been warnings to this extend in a couple of loading manuals-excluding Lee's.

Everybody obviously needs to do what he or she feels is best. Personally, I value my guns, hands and eyes over the cost savings of salvaging "Glocked" brass. Regardless of how many you've salvaged, reloaded and fired-it only takes one.

For what it's worth.

They acually recomend that NOT reuse "Glock" brass
(or unsupported chambers to be exact)

##Glock Cases: We do not recommend "fixing" cases fired in pistols with unsupported chambers, because there is no way to make them safe once they have bulged. The case wall is thinned where it bulges, and resizing the outside of the case back down to the correct diameter does not restore the case back to its original thickness. If this case is fired in a pistol with an unsupported chamber again, and this thinned section of brass happens to line up with the unsupported part of the chamber, there is a high probability that the case will rupture.##

IMO, you are mistaking the diff in a bulged case vs work hardening. Once you get to a glock smiley, the case has been damaged in the bulged area. Resizing in a pass thru sizer would eventually cause a failure in that location. It's brass, toss it. If your loads are causing the bulge, time to back way off.

Pics.....People Pics. As I have never owned a Glock or reloaded Glocked brass as far as I know. Just got 1000 9mm once fired brass . You bet I will be looking at each piece . I have seen brass shot in a unsupported chamber before but never seen smileys on them.

Don't believe I would reload any case that looked like that. Heck I toss them if they have tiny dents in them. Been called OCD many times. Thank for the Pic.

Below is a case fired in a "generous" size chamber and what the bulge buster kit is for.



The "smiley" fired case below should "NOT" be reloaded because the brass is over stretched and weakened.



Below the "smiley" caused the case to crack and "why" theses cases should "NOT" be reloaded.



I have a newer Glock and it does not bulge the cases. The problem was the older Glock barrels and thin cases. The barrel problem was fixed and the cases were made thicker. I use range pickup once fired brass all the time and common sense when inspecting the brass is all you need.



From the Lee Bulge Buster web page below.

Glock Cases: We do not recommend "fixing" cases fired in pistols with unsupported chambers, because there is no way to make them safe once they have bulged. The case wall is thinned where it bulges, and resizing the outside of the case back down to the correct diameter does not restore the case back to its original thickness.

I know there are some old guns out the but didn't Glock fix the unsupported chamber thing many years ago. And if I remember, that was with the .40 cal models, not the 9mms.

It was only a issue with 1st gen 40s. The other calibers were never an issue. My 1st gen g17 has had some ridiculously loaded 9mm & no case bulge.

Have been using the bulge buster on all my 40's and
.357 Sig's they say it can be used on .9mm using Makarov
9mm crimp die but not for me. Most early gen Glocks have a partially unsupported chamber that causes case bulging.

Again, the unsupported chamber issue in early glocks is only relevant to the 40. Never seen a bulged case from a 9 or 45. I fired over 1000 +p+ Equiv loads they my 1st gen, stock g17, hot enough to stretch primer pockets, no bulge.

Work hardening is a metallurgical phenomenon that occurs in all fired cartridge brass. Bulging, as the term is being used in this thread, is the assymetrical deformation at the case's base from an un-supported chamber feed ramp. bigedp51's excellent photo comparison above illustrates the difference. A bulge so severe that it causes a crease should be discarded (Judgment!). A bulge with a smiley face has two problems, excessive strain hardening, and stress discontinuity that increases failure probability. We are saying the same thing, but from different perspectives. I do not own Glocks or any other semi-automatics with chamber cuts to ease feeding and extraction (example, H&K fluted chambers). I prefer tamer firearms, easier on brass and me. I do, however, shoot Lee-Enfields with lop sided, over-sized chambers that will form brass into assymetric helixes, my flirtation with case failures. Gotta use judgment to toss the risky stuff.

Again, the unsupported chamber issue in early glocks is only relevant to the 40.
In view of the fact that the cases used in "The 10 Ring" thread were 10mm, it would appear that the problem was not limited to .40 S&W.

Just to clarify.
