There are huge pine trees near me that have scars that look like that from lightning strikes..... thats what those reminded me of.
Look at the bulges in some of those cases, you wonder what the chamber looks like? |

^^ Bruce : That's a good explanation why they did that ( I didn't think of that one )
But to keep doing it for at least 20 rounds !

I shot a belt of .308 out of a 1919 chambered in 30-06.
I realized the error when I picked up the brass... I wondered where the 45-70 brass came from and I realized that I had blown out the neck and shoulder of the .308 The .44 brass is crazy. I guess that they were not checking there empties

That is neither acceptable or safe behavior from a gun. I have shot several desert eagles before and none of them trashed cases like yours does! Your gun has a problem that needs repair. And as for semi auto vs. revolver, that has nothing to do with the brass splitting shown in the first post of this thread. Go look in a reloading manual at the case dimensions of 44 mag and 45 colt...

Sometimes, I think there should be, but I can only hope that natural selection weeds those people out... This is the most likely cause.

The only way a case splits like that is from being fired in a chamber that is way out of SAAMI spec. This is case fatigue ![]() This is neck fatigue ![]() And this is a chamber that is much too large ![]() You should look into cerro-safe casting the chamber and finding out what the deal is. I'm not sure of the particulars of the gas system on a Desert Eagle, but you have a problem with yours. |

I have at least 2.5K through my DE in 44 mag and have never split a case like that. That is with max charges using H110. My 50AE brass usually only last 2-3 firings due to the neck splitting when slightly belling them.

Those splits can be the result of over sizing with a single ring die carbide die, then expanding short and applying a heavy crimp. The bullet will produce a quite noticeable bulge in the case and split upon firing. Usually it takes more than one firing to split the case, depending on the brass age, hardness and manufacturer. This is often caused by a reloader that is attempting to remove the case bulge from the head area after firing with a carbide die. Carbide dies are only for neck sizing down to where the base of the bullet sits. Even straight wall revolver cases have a slight taper to the case body, and running a carbide die to the base will remove that taper. Just sizing a little too much below the bullet base can lead to the problem.
If the expander stem does not expand the brass to where the bullet base is seated, the brass will be stressed at the bullet heel, which is why the case splits from that point downward to the thicker brass near the head. The cases appear to have been fired in a larger chamber because once the brass split it lost the ability to spring back into shape after firing. This is especially noticeable in cases fired in revolvers with maximum diameter chambers. Redding sells a dual ring titanium carbide die that corrects this problem: http://redding-reloading.com/index.p...g-carbide-dies I have experienced this problem, which is why I discontinued use of carbide dies for certain revolver cartridges in favor of standard full length dies. The splits are not the result of high pressure or being fired in the wrong chamber, but are the result of over sizing and under or short expanding, that resulted in over working the brass, leading to failure. While the problem exists primarily with carbide dies, it can also occur with steel dies where chamber and die dimensions do not agree. The picture of the split necks on bottle necked cartridges can be due to a few other factors other than metal fatigue. Older lots of military ammunition can fail with split necks due to age hardened bullet sealer, and galvanic neck to bullet welding by ionic displacement. We often forget that dissimilar metals can be subject to cold welding from a chemical reaction between them. When I decided to pull apart several hundreds of rounds to scrap the brass, it was found that some bullets couldn't be pulled using a collet or inertia puller. Remembering the cold welding factor, I found that by seating the bullets deeper until I heard a loud 'snap' signifying the bullets had broken loose, afterwards the bullets pulled readily. While this ammo dated to the 1980's, the process begins as soon as the ammo is loaded. Last edited by Wrangler John; 12-05-2012 at 5:01 AM.. |
