[QUOTE="700lr, post: 984143, member: 83207"] Bumping the shoulder will not affect neck tension, just headspace. To increase neck tension you must know a particular measurement associated with your brass and purchase a die such as the Redding type S, bushing style, full sizing die. After you take a measurement you can order your die and the appropriate bushing to reduce neck diameter to whatever you want. If you want to go tighter than the expander ball will allow, you just remove the expander which is typically .001 less than the bullet. Redding provides a replacement for the expander ball if you decide not to use it. The replacement tip holds the decapping pin with no neck expansion. Measure the neck diameter of a loaded round, order a bushing .001 or .002 smaller than this outside diameter. The bushing fits into the die, and upon sizing will reduce the neck by that amount. For example, if you measure a loaded round at the neck and it measures .336 and you want .002 of tension, order a .334 bushing. Read the die instructions carefully and follow them. Hope this helps.
