I suspect your are correct, that it failed due to cheap manufacturing. Well, I paid a low price. I should expect lower quality and plan accordingly. I did think that annealing referred to a process of heat-treating the mouth portion of the case to...well, I'm not sure why. But I don't know why a casing would "lose" it's annealing. I thought it either was, or was not. I loaded some old, old brass today. Some of it was .45ACP from Armscorp from 1982 or so. It worked for reloading (after cleaning.) I fired 50 rounds successfully. There was no damage to the case, particularly around the mouth. Odd. | |||

Annealing is a process to make brass softer and more pliable. Being a process, you cannot lose the annealing. Perhaps she mistakenly means that the brass has hardened with age. However, I have never heard of brass hardening except from being worked. Brass is created by drawing a brass button over mandrels to form the case. This definitely works the brass and makes it harder. Most likely the brass was not properly annealed after being drawn during manufacture, not from storage. I have a case of 303 Brit manufactured in 1944. It shoots fine and doesn't split. If stored brass did "lose its annealing"(hardens), that stuff should be splitting wide open. Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well. -Epictetus | |||

This. What you got was an excuse that said "We really don't have any idea and it's not worth the costs of our time to find out what was wrong. Here, go away!" Either way, good that they responded and made you whole.

Brass does lose it's annealing as it gets older, I believe from microscopic corrosion. As brass ages, it gets stiffer...... A common practice on the older large diesels (MTU, etc.) that use copper washers (since the engines are dinosaurs the parts sit on the shelf a long time) is to put the copper washers on a metal coat hanger and heat the hell out of them and let them cool off, before using them on the motor to soften them back up so they "crush". | |||

Agreed. I'm not a metallurgist, but I am a metallurgical junkie (the topic fascinates the engineer in me so I read a lot as well as hang out with a lot of oil & gas metallurgists). I found zilch after checking a few references as well as Google. Corrosion is not loss of annealing, corrosion is a loss of electrons. Annealed brass is one of the alloys susceptible to stress corrosion cracking, but that isn't the OP's issue (if it was, the OP would have had split cartridges). You can't compare copper and brass. Once the copper has been alloyed with the zinc, it behaves as the new alloy. Cartridge brass has about 150% the tensile strength of pure copper, but significantly less conductivity. Additionally, cartridge brass has different cold working and hot working properties than copper. They manipulate the % of zinc in the alloy to achieve the desired cold working and hot working properties.

I recieved 500 rounds of .38 special a few minutes ago. I'll never know what happened, most likely, but I do know that in my 50 years of gun ownership and shooting I never had a similar experience. Oh well. | |||

Had a similar issue with some .44 magnums which turned out to be too light of a crimp. ______________________ Semper Fi | |||

OP, I once had a brand new S&W scandium 357 I was going to carry off duty, so I had to qualify with it. I went to the range and promptly kablammoed it on the second round....the first round was a squib and the second one did the work of two. I called S&W to see how to send it in for repair and they asked what kinda ammo I was using, (Winchester) and they asked to send it along with the gun. a week goes by and I call to give them my Visa number and the gunsmith who was working on it talked with me. they never wanted a card number and repaired it free of charge and forwarded it to Winchester to have them investigate the ammo. I never heard anything further about the ammo. Glad that you and your gun didn't get hurt "Violence, naked force, has settled more issues in history than has any other factor.” Robert A.

And the latest on the same issue-I opened the new case sent to me by Remington yesterday and headed for the range. I fired them in a Taurus Non-View-squib on round 3. Okay, maybe the super light gun was acting as a bullet puller. Loaded the Kimber K6s. Round 2 tied up the cylinder with a squib. I went home and emailed Remington. They sent me another shipping label and promised reimbursement this time. Hope I get the check before they go bankrupt! | |||

I had a Ruger LCR 9mm revolver that I bought for my wife. Five round cylinder. Ruger's manual suggested that this revolver could be sensitive to the crimp in ammunition and suggested testing by measuring OAL of a cartridge, loading five rounds, firing four, and then measuring OAL once again of the remaining, unfired, cartridge. With my handholds, experimenting with crimping, the fifth bullet in every cylinder walked forward anywhere from .020" to .050". I tried store-bought ammunition and on every trial the forward migration was anywhere from .020" to fully out of the brass case. I sold this revolver, with full disclosure, to a forum member here and replaced it with the same type Ruger LCR, but in .357 Magnum. No problems here to date with any store-bought ammunition. I am not set up to load .38 SPL or .357 Magnum, as I don't shoot enough of that to make it worth while. הרחפת שלי מלאה בצלופחים | |||

What is happening? Is the bullet moving forward in the fifth cartridge from shock and concussion? Is the pressure from 4 shots squeezing the remaining cartridge pushing the bullet forward? This is something I have not heard of... | |||

This is pure bullshit. Remington is in the toilet financially, and clearly it is circling the drain operationally now, too. Thanks, Sap | |||

Reloader here for about fifty years,the umc brass is what I chunk in the scrap bucket. The company is out for squeezing out all possible profit. The 38 brass the op has the problems with is caused by Remington having its brass spun about three k thinner than quality ammo manufactures. I experienced this fact decades ago when loading a new jacket bullet into their [umc]cases,bullet would fall on its own down to powder. | |||

Prepared for the Worst, Providing the Best |
I've seen this too, but not all umc brass, just some older stuff I picked up somewhere. It is truly some crappy stuff, though. I've had a squib with it, too, but thankfully caught it before firing a second round. MikeinNC, having shot several of those scandium Smiths in .357, the thought of having one blow up in ones hand is extremely unpleasant. Those things feel like they're exploding in your hand when they function as intended...I wouldn't want to be holding one when something went wrong. Glad you're ok, and still (presumably) have your fingers to type about it! | |||
