[QUOTE="MagnumManiac, post: 2970008, member: 10755"] A question for you: How much does running a mandrel, or neck sizer then mandrel, change neck hardness due to work hardening, or seating a bullet with an additional .0015-.002”? Most believe that this isn’t something to take into consideration as they believe work hardening only happens over time if not addressed. I do not believe this to be true because I can measure seating resistance with new untouched brass, then measure a case that has had the above steps done and note a difference, just as Eric Cortina’s tests have also shown. Any brass movement one way, then the other way at ANY time will cause work hardening… Cheers. [/QUOTE]
