Partial re-sizing and neck tension?

[accubond]

A few of my buddies and me partial re-size for most of our guns. I have noticed on some of them that when bumping the shoulder back about .005" compared to a fired casing only part of the neck is being re-sized also. Some of these are half or less and we dont crimp any loads or buy bullets with a cannelure. I would think this would make it easier to get some bullet run-out and possibly have a bullet slip, changing your O.A.L. Have any of you guys noticed this while partial re-sizing and what if anything have you done to address it. I think I might order a neck sizing die to partial re-size and then follow up by sizing the whole neck. Any feedback would be greatly appreciated.

ya, some dies you just cant get away from it..I have been slowly replacing all my dies with bushing dies..if your gonna get a neck sizer, spring for the bushing type, RCBS even makes them now days.
