I've been reloading 9mm, 40S&W and .45ACP for a while now.. and have managed to reload and successfully fire thousands of rounds to date. In never use hot loads.
That being said "most" of the brass I've used has been from commercial brass I've purchased new and has reloaded just fine. However recently I purchased 2000 rounds of Federal .40 S&W "one fired" brass. Although the inside of the cases don't show signs of being reloaded many times (not black) I've found several that have split case mouths. I've found a few when reloading, one after firing.
Most of this brass not Glock fired and resizes fine and seems to hold the bullets quite well.
Are there any other signs to look for? Is case head separation something that can happen or is that rare is typical handgun loads? None of them show any signs of this fwiw. None of them seem to have loose primer pockets either. Could it just be old brass that may have become brittle?
