I have never run into this so what say you?
Believe there is a die called "bulge buster" available.
Of note, the ONY straight wall pistol case that has failed after reloading, nickel plated that had a bulged case.
Have successfully reloaded brass cases, with bulge, with no issues.
https://leeprecision.com/undersize-sizing-die-40-s-w-10mm.html and that fixed the issues. I was using the bulge buster but was still losing cases when I would case gauge. The undersize die took care of that and maybe 2 outta a couple hundred still wont pass muster. However I am on reload #9 of the cases.
Get a .375" oak dowel rod and cut it to about 4". Round off the edges so each end fits in a .40 case. Remove the top of the crimp die so you can see all the way through it. Put a case on each end - one to hold the dowel on the plate, one to be bulge-busted - and press that brass upward through the die. It may help to occasionally lube a case to ease the cases through the die. There is a u-toob video out there.
Check bulge-busted cases for length. Hope this helps.
Good grief. I'm only on reload #2. I fear I already have a lifetime supply of brass.
Just for accuracy sake, the die is the Redding G-Rx (Glock Prescription)
This is what I use also. All of the range pickup .40 brass goes through it. I even run once fired LE-training brass, that has run through SIGs, through it. You can easily feed the difference between normal expanded brass and budged brass...I'm getting about 10% budged...when you hit a piece of brass with "guppy belly" you'll definitely feel the stop.
The Lee Bulge Buster is a bit less expensive, but you have to keep two things in mind:
1. You have to add the correct caliber FCD to the kit
2. You have to balance the case atop the pusher with your fingers until it enters the die...the Redding has a retracting sleeve that holds the case as it enters
I did have some 45 ACP brass that was badly bulged and successfully saved it. I also have some 45 Colt dies. So I resized the brass using that die first and resized with the 45 ACP die after. All plunked and none have ruptured despite having had good sized guppy bellies when I scrounged them at the range. YMMMV
ETA: I bet using a 41MAG sizing die would do the same with a 40 although i do not reload 41.
If the cases are bulged badly enough that some crack, he should scrap them. Ironing out a small bulge is generally safe; ironing out a bulge so large that the case cracks in a FL die is just asking to ruin the pistol and test your eye protection with a blown case.
Scrap them or return them. Shooting bulged/cracked brass in a plastic gun = trip to emergency room.
35,000 PSI when turned loose , not good.
EDIT/ADD- Some internet photos , as a reminder.
Only takes 1
The brass we run in our SMG's gets blown out though and I always make sure to run them though one of my roll sizers before they go through the reloading operation.
If the brass split upon a trip in and out of a standard size die, it was already gone though. Its not like anyone in their right mind would suggest annealing the case head.
Can you post a photo?
There is a pretty good ring around the bottom on the side the bulge was on that actually left a sharp edge. I have seen bugle before but nothing like some of these. Also, some of the primers appear to be reloads IMO. They are awfully flat and gold color in I believe federal brass.
I will post a photo later tonight.
He just ordered them and they arrived last night. $76 for 1k 40cal supposedly once fired. If they are indeed junk, I'll tell him return them and if they give him a hard time to call his CC. Its about 90% of the cases that have bulge.
I ran about 1K pieces of .40S&W brass through a Redding G-Rx die about a month ago.
Most have since been reloaded and shot in two different .40S&W handguns (S&W M&P and a Beretta) with no issues.
The Redding G -Rx die works great with little effort. I did spray the brass with Hornady One Shot lube before running them through the die.
The cartridges were reloaded on my Hornady LNL progressive press and it ran flawlessly after using the Redding die.
My calculator says just under 10pounds
Lee's website has a warning that once a case is bulged, it will never be as strong as it was when new, even after the bulge buster.
Buying more equipment and spending extra time passing crappy brass through a separate operation is a waste of time and money.
Emailed company with same explanation. Waiting for response
Is that a crack or brass shavings shoved down the case?
Do you have tools to cross section one?
What size die are you using?
Wet tumbled and squeaky (in the size die) clean?
Do you have any case lube you can apply to see if it solves the problem?
