To start off I received my first handgun a smith and Wesson model 65 4 inch 357 Magnum for Christmas when I was 12 with it came a one or two boxes of Remington 158 grain Soft point ammo. My dad was such a proponent of the 357 because the 38 special could be shot as well and true to his thoughts I shot more 38s out of it than anything as I got a lee loader the next year at age 13. I am now 27 and still have both the revolver and a partial box of my first 357's and my dad passed away Oct 31 2018 at the age of 72. I felt a might whimsical in the process of remembering these moments and decided to take some of those 357's out and relive a moment. The first two rounds were just fine it was the third that locked up. Upon opening the cylinder and dumping the rounds into my hand I saw the problem, bullets had jumped the crimp. It was a first as these were mild loads compared to my 14.5 grain load of 2400 and a lyman 358156 HP gas checked bullet. Upon further inspection it was found the cases all had splits about 3/8 of a inch back from the mouth. No tension, how strange for factory ammo. I have pulled the bullets of the offending cases and perhaps I will re use them in the future as they sit now they only serve as a warning to be aware of the condition of your ammo.
PS the ammo was stored in 60-70 deg temps, dry, and with other factory loaded ammo that did not show any of these signs.
