[QUOTE="MagnumManiac, post: 2421508, member: 10755"] You are completely wrong. It is called “Cold Weld” for a reason. It is the electrolysis forming a residue that locks the two metals together. As a normal round fires, the neck, being thinner, expands first. Even .00001” of expansion is enough to release the “grip” on the bullet. However, in this instance, the grip on the bullet is a heck of a lot harder to break and can and does cause pressure to spike if it is already at or near max. Many instances of this phenomenon have a corrosion inside the case. Many bullets pulled in this condition also have corrosion around the base of the bullet and on the insides of the brass. Look up electrolysis regarding lead and aluminium and tell me that this is not similar. Cheers. [/QUOTE]
