    Split .30 Carbine cases

    I went to the Range today to fire my Inland carbine that had been rebarreled with one of the barrels from Fulton Armory. This is the second time that I have fired my carbine since the rebarreling and it has had a total of 80 rds put through the new barrel. Out of the 40 rounds that I fired today, I found three caseings that are marked " W-W .30 Carbine" that were split as shown in the photos. Does anyone know what the cause of this type of splitting could be? I've had these particular rounds for many years sitting in strippers so I don't remember their origin. I don't think that they are reloads since I've always stayed away from using that type of round. I always try to use factory loads. Thanks for any help.

    The splits could be caused by brittle brass, either being reloaded to many times or by old age. Could also be caused by the chamber being a little to loose, however the cases in the picture don't look bulged out. I'd guess brittle brass.

    It appears the metal at that end of the cartridges were too thin and stretched to the point of cracking when the cases expanded during firing. This is typical of cartridges reloaded/resized too often. If these were new cartridges, it may be a manufacturing defect or metallurgical defect.

    I have had the exact same experience with the WW brass. I too believe that it is brittle brass.

    I have found the same split cases on American brand .30M1 ammo. I think they are located in Florida.

    Amerc is known for its bad brass. I won't even try to reload that junk.

    I had the same thing with s&b ammo. About 10% split when fired. Try a diffrent brand of ammo. Proubally defective brass. I have a few hundred LC-55 cases that are on their 5th loading and they are still holding up.

    I don't even know how many times some of my carbine cases have been reloaded. I'm sure some of them have reached 20 times by now. Keep the loads reasonable and the only thing you need to worry about is wearing out the primer pockets.
