[QUOTE="Longtine88, post: 2735568, member: 116240"] You still have to size your neck down even for the mandrel. With a bushing or FL die I bump my shoulder back the 0.002. Depending on how much you size the neck you're going to have to play with the mandrel size until you get the tension you want. So if I were trying to get a neck tension of .002 for say a 30 cal I would pick the 0.3070" mandrel because your neck generally will fall back depending on how much I squeezed the neck die. If I use a bushing die and the bushing gets me to my 0.002" perfect then I still will run my 0.3075" mandrel through it and then it's perfect. People will say you're just wearing out your neck, but since I anneal after every firing it really doesn't matter. The combo works for me. I produce a lot of one hole groups so I guess the proof is in the pudding. [/QUOTE]
