bumping the shoulder back?

[kennedy]

how do you do this, I neck size only .308 with lee dies, and shoot them in a rem 700, some times the bolt sticks, so how do I bump the shoulder back?

Body die, or full length die. Since you are neck sizing, you may want to use a body die.

+1, I use my 7.7x58 FL die as a neck size/body die every 4th firing. I have no problems getting 10+ firings out of a batch of casings. Leave the shoulder where its at to avoid case stretching.

 

[W.E.G.]

Get a case gage, and adjust your die so the cases gage correctly.

do you run the fl sizing die all the way down or just part of the way?

some times the bolt sticks

Is this whilst chambering a fresh round or extracting a fired case?

You maybe able to size the base of the case enough with a full length sizer die and maintain a minimum headspace, by backing it out some, then adjusting it down and checking the sized case in the chamber.
Once you find the point at which you have sized cases that chamber without sticking. Then try it with a seated bullet. You should then be able to resume necksizing on those cases once fired in your rifle.
Or like mentioned, a body sizing die will simplify things.

The RCBS Case Gauge that W.E.G. illustrated is IMHO the easiest and most helpful tool that you are in need of. You will be able to determine exactly where to set your full length sizing die to headspace your cartridges to your rifle's chamber correctly.

Good luck!
