auto you should bump .003 at least. I find with .001 to .0015 in my rifles I get good chambering and good case life.The original poster is not FL resizing cases that he shot in another rifle. For a hunting rifle there is absolutely no need to partial size or neck size. You should FL size every case.
I'd really like to know how you can measure to within .001" to a rounded case shoulder? Unless you have a superb set of calipers that is pretty hard to believe unless you could measure the same dimension, say, 25 times and get the same repeatable results then I would agree.
I'm just trying to imagine how you bump back a shoulder in a standard die without FL sizing. The way a die is designed the shoulder should not get touched unless the case is inserted fully into the die.
If you read my post I use FL sizing dies, if you don't know all you have to do is bump your shoulder back to ensure easy chambering and long case life I would suggest looking into a Hornady Headspace kit. If you keep sizing your cases by constantly over camming the dies stretching the case each time you are going to have case separations.

RR why would you need to expand the case neck? It should be "oversized" after firing. But other than that it sounds logical for THAT rifle only.
But for hunting rounds I would definitely FL resize. If I should need a fast follow up shot I don't want to have to be messing around with a less than slick bolt. I would want the least resistance possible. Shooting competitively or just for targets is another story.

some chambers which are within spec could vary enough to cut brass life dramatically just a fix for that problem. if you form cases for wildcats you want all the brass life you can get.
