When to full length resize
I'm reloading 7MM-08 (not that it matters) and have been neck resizing only. I've read that periodically you need to full length resize cases after you neck resized a number of times.
I've got a couple of questions.
1. If a case forms to your chamber when you shoot the gun, why would you ever need to full length resize? I understand why you need to periodically trim the case length, but why would you have to occasionally full length resize.
2. If you do need to occasionally full length resize, how do you know when you need to do it? How many times can you neck resize only before you need to full length resize?

RE: When to full length resize
firstshot,
It is true that you will need to bump the shoulder back from time to time when neck sizing. How often? Perhaps after about every 5 firings when neck sized. When will you know? When you try chambering a recently fired case and you noticed a little stiffness in closing the bolt. An excellent die to use for this is Redding's Body Die. This die resizes the body without touching the neck, so after using it, you must once again use your neck sizing die prior to loading. Hope that helps.

RE: When to full length resize
I definatly would after 3 firings. I am not a big advocate of a neck sizer. sometimes cause more problems than good with neck runout. I do like the lee collet die however.
After 2 or so firings you can get very tight chambering and cause you some grief in field conditions. I have heard many times people saying, "there's never a need to full length" and on more than one occassion, it took them a bad experience in the field during cold weather or hot weather, for them to quickly change thier tune.
I am hunter first and formost. I usually can get great results Partial Full Length sizing. If I can't I do some work on the gun.
What happens, is when fired, brass does expand to the chamber but springs back some. After 2 or three firings, of being expanded, it bonds better and better to the chamber.
HDW, very well know fact my friend. Surprised you have seen or heard it.

As you know BC i use the lee collet neck sizer dies, with them I havent had to use my FL die yet to reset the shoulders on my 308 and 30-06 loads. However my hunting loads are FL sized just incase i did run into chambering/ejecting problems.
edit: I must have assumed firstshot was using a collet die.........
