I like the Redding "S" type bushing FULL COMPETITION 3 die set. Most of the time I am only sizing the neck and with the titanium nitrried bushing no lube is required. I also like the fact that a seperate ( the third die) body die is used when you need to bump the shoulder back and I feel this is aids in concentricity. With this system you are only sizing the neck a few thousands and the expander ball has little or no work to do or can even be removed. I feel all of this will greatly extend case life. That will leave the rest of the case to a nice fireformed fit to your chamber. Another great feature of these dies is that they have a retractable sleeve that captures and squares the case to the die before any sizing in done to the neck. Again, great concentricity. I maintain a total runout of .001" or most of the time less.
These dies are a bit pricey, but I feel they are frutal in my attempt to build the most consistant ammo I can. I also feel that helps me at ranges of 1000 yards and over. At those distances I will do anything I can to gain even the smallest amount of consistancy. gun)
., I talked with one of the Redding technisions and if I understood him right The only advantage that the Type S competiton bushing dies have over the regular Type S bushing dies is the micrometer adjustment. Other than that they basically do the same job..-MR
