[QUOTE="Openlake, post: 5665401, member: 1098"] I’ve been loading for 36 years. I think I had a real close catastrophe from a similar cold weld. .270 Winchester, 140 Nosler Accubonds. My son’s Winchester Model 70. Shot this load for 10 years without issue, and not a hot load. He went to college and didn’t shoot for several years. After college I loaded up some new ammo for him to hunt with. At the range we always have the practice of shooting the oldest ammo first. His first shot had smoke boil from the action. The case head was severely cracked, primer flattened, definitely a high pressure situation had occurred. My first thought was he had an obstruction in the barrel. However he had cleaned it a few days before shooting. After reviewing the ammo we came to the conclusion that the older rounds had been used from a hunt trip 5 years earlier, in the rain. I think those wet conditions along with time created a cold weld on the cartridge that had been chambered during that hunt. Possibly a little unseen corrosion. All the other old ammo and the new batch have shot perfect since. [/QUOTE]
