What temp range, Do I use for .308 win? How much of the case needs to be annealed? I use the lead pot method.

I do not know about the "lead pot method", so I won't comment on that.

I was taught to use a regular old plumbing torch to anneal the neck on bottle neck rifle casings, and this method needs to be done outside. 

Do this at your own risk ON CASES THAT ARE NOT PRIMED.
 
Set up your torch and have a catch bucket under the flame.

While holding the cartridge by the head (and perpendicular to the flame) rotate the neck of the cartridge in the flame until you just start to feel any heat. 

Drop the cartridge in the bucket.

The neck is now annealed.

It is simple, but it works.

The Lyman 49th manual cautions against attempts to anneal case necks. "By the time a case neck needs annealing at the neck, other factors have brought about the end of the case's useful safe reloading life." That's good enough for me. Now if your forming new brass for a wildcat, that's a different story. I think the lead pot would be the most uniform temperature control.
