I use a Redding Type S Bushing FL die with a .328 coated bushing for my 30BR. I use Imperial wax on the body and nothing on the shoulder or neck since the bushing is coated. Right now I have a Wilson seater, but may get a Redding comp seater so I dont have to carry so much stuff to the range.
My Redding die pushes the shoulder back .001, reduced the shoulder dia. by .001, and the base isnt reduced at all. It resizes my cases pretty close to chamber specs, so I got lucky in that regard.
My normal sizing routine is to remove the decapping assy and bushing, run the case in to size the body and bump the shoulder, the I put a 1/8" spacer under the die locking ring, replace the bushing and decapping pin, and size the neck. By stopping short 1/8" on the neck, it centers better in the chamber.
My rifle has a .332 neck, the necks are turned to .011 for a loaded round O.D. of .330.
