[QUOTE="cohunt, post: 2666810, member: 94491"] This has been brought up before and the "cold constricting bore" thing was kinda de-bunked by a guy that actually knew the amount of "shrinkage" a steel bore encountered. He said that copper and lead shrink at a higher rate than steel does so yes the bore does "shrink" but the bullet shrinks more than the bore does.....he actually had numbers to prove his theory. That makes me think its gotta be a powder thing [/QUOTE]
