Bulged Cases
I really get upset when I hear folks talking about ironing out a bulged case. What causes the case to bulge?
In most instances it is the unsupported portion of the chamber that allows this to happen. Two possibilities, as I see it. One, the bulged case may have been in perfect condition but the load could have been too hot causing the bulge. In this instance, the case has been weakened but the bulge itself. It is further weakened by the ironing out. This case should be scrapped. Two, if the case was weak in the first place, you can consider yourself lucky your gun didn’t do a self disassembly. In my opinion, reloading an ironed out bulged case is just asking for trouble. Any thoughts? Chris |

The infamous "Glock Bulge" occurs on factory brass as well as reloads. What harm is there in ironing out the bulge? Should we throw out once fired rifle brass instead of resizing it?

If it is bulged, yes you should toss it.

I guess you better hurry and get the word out to the thousands upon thousands of people who iron out the bulges in their 40S&W cases over and over without incidence....
Do you REALLY think that MFG's would make products like bulge busters if there was ANY chance that it would cause what you are worried about here? |

If this were true, then pushing the shoulder back in other high pressure cartridges wouldn't be a common practice--and it is. Same goes for fire forming brass, and wildcat alterations of one brass into another--all of which is done very regularly. It doesn't hurt anything other than work-hardening the brass over time. It will become brittle after a while, but debulging is nothing new or dangerous. Do what you like with your brass--just don't keep propagating bad information based on personal opinion. Thanks.

Geez, some people worry about the darnedest things! Yes, the bulge IS caused by the feed ramp, unsupported portion of the chamber. No, it does NOT weaken the brass! That's the reason the cases are made of brass. It's resilient to allow re-forming again and again.
Find something to REALLY worry about, like no powder in a case, then seat a bullet,(squib). Or loading without a loading manual. The list goes on and on about real concerns about reloading/handloading. If you're going to scrap all your 9mm, 40 S&W, and 45 bulged cases, toss them my way, I'll pay you scrap brass price AND pay postage to send them to me.

That falls into the same category as my wife complaining about having to run laundry through the rinse cycle twice because the clothes are still soapy. I tell her to cut back on the detergent.
She says ... the manufacturer says to use this much. I say ... if I made laundry detergent I would tell you to use the absolute maximum amount so you run out more quickly and buy more at the grocery store. She says ... so you know more than the manufacturer. I say ... God gave me a brain. I thnik his expectation is I use it.

I just stated an opinion. As an opinion, there is no evidence, on my part. Just opinion.
Now, Hammerhead has actually quoted from Lee. Thanks Hammerhead. Nuff Said. Chris |

*evidence= the thousands of thousands of cases that have been repeatedly fired in glocks without bursting.... As always though, use common sense and inspect your cases. Its obvious that repeatedly ironing out the bulge, just like any other resizing will work harden the brass after some time. These cases should be checked for impending case head separation just like any rifle cartridge thats re-sized.... Also one should use common sense in not trying to iron out rediculous buldges and all will be well. It seems using the same inspection process I use for dents would be a good idea, if there is ANY crease or sharp ridge, toss it, if its a smooth dent (bulge) you are ok. Lastly, if you dont feel comfortable reloading slightly bulged cases, dont do it, no one is going to force you! OTOH, many people do it without issue, and should not be looked down upon, they are not "asking for trouble" as long as they are using common sense. |

Hey snuffy, you mind if I get in on some of the ship-me-your-bulged-scrap-brass action?
Since my primary brass collection point is the range used by the local law, I strongly suspect that around 10K of my 12K pieces of 40S&W were "Glocked". Easy to tell the Glocked pieces by the rectangle imprint on the primer. Easy to ID the brass shot in the older Glocks by the "belly." My opinion on bulged brass... ...use 'em til I lose 'em.

i have loaded bulged glock case 20 times before i finally retired them. I use a gnx die from redding and have experienced 0 issues in over 30k rounds reloaded and shot in the same glock
if fixing a bulged case technically any case that needs to be run thru a resizing die should be scrapped since they are bulged from at production time. |

On second thought maybe some of both.

Generation 1 glocks had a VERY large feed ramp on the 40 S&W barrels. That's where the myth comes from about glocked brass not being safe to reload.

This is what is so loveable about some of us. We are not willing to take the opinion of others, nor are we willing to take the opinion of the manufacturers. It is our choice, which is true.
Granted, disclaimers from manufacturers are lawyers. So, from where do these lawyers get their information?? .......The manufacturers and engineers themselves. They just try to translate engineering into lawyer. We are each free to choose. But we are not free from the consequence of our choice. Chris Last edited by varmiter; March 17, 2012 at 09:13 PM. |

"No one told me a little tube generating 30,000psi or more could be DANGEROUS!! It's all the manufacturer's fault for providing me with the means to be a complete flipping moron!! SUE! SUE! SUE!" Kind of like the McDonalds lawsuit for spilled coffee because "no one warned me it would be hot"... THAT is why there are disclaimers on everything including your socks---because people in general tend to be ROCK STUPID.

No, I think I will take the ACTUAL experience of thousands of like minded individuals over some lawyer speak written up as a CYA.... Real life proof and common sense is what I base my opinions on. Others are free to base theirs on fantasy, what ifs, and imagination if they so choose. But I wont stand by and allow them to help form others opinions based on their fantasy. In today's society, They can put all the warnings they want on something, but if its TRULY not safe, they ARE going to be sued. A disclaimer like that means NOTHING in the courts. Honestly, can you imagine the case? "well your honor, yes we did manufacture the "bulge buster" in question, but we included a disclaimer with it that nobody should use it, so doesnt that free us of liability?" It would be like someone selling a coffee maker with the disclaimer, "DO NOT MAKE COFFEE WITH THIS IT COULD EXPLODE". Then, when thousands of people have coffee makers explode in their face, the MFG goes "nope, we told you not to make coffee in that coffee maker" You KNOW the judge is going to go "you sold an unsafe product, so you are liable" |

+1 to what Lee Precision posted.

If a case don't fully resize on the first attempt, I rotate the case 90 degrees and resize again (and this is with the regular resizing die). If the case won't fully resize on the second attempt and pass the case gauge, I deem the case overstretched and overly thinned to be reloaded safely and recycle the brass. In addition to Hodgdon's warning, here's another from Accurate Powder: http://www.accuratepowder.com/safety...atic-handguns/ Quote:

Not all bulged cases are the same. Here are some bulged cases shot in looser chambers. Most of these will fully resize in regular sizing dies.
They can be resized flat like this (If they don't fully resize on first attempt, I rotate the case 90 degrees and resize a second time. If they won't drop in tight Lone Wolf chambers freely after being resized twice, they get recycled). BTW, I used regular Lee carbide sizing die. If your cases are bulging and you are not comfortable about reloading bulged cases, reduce your charge, change powder or use an aftermarket barrel that has tighter chamber that won't bulge the case. All of my spent cases from Lone Wolf barrels show no bulge. Last edited by BDS-THR; March 18, 2012 at 03:30 PM. |

My Bulges are gone
I had the same issue with my Lee dies for 38 spl and 9mm before I put on a Pro Auto Disk powder measure. Once I did the problem went away with both sets of dies. Obviously more flare somehow.
Maybe you could put a washer between the plug and the powder funnel adapter in the die to give more flare if you dont have one. As long as it doesn restrict powder flow. PMC 38 spl cases are the only ones I have had some issues with on the FTD scraping a little and they are thicker than most. Last edited by marklyftogt; March 28, 2012 at 07:06 PM. |

Unsupported Chamber?
Do all pistols have an unsupported Chamber or is this only some?
