[QUOTE="Brent, post: 71416, member: 99"] [ QUOTE ] [ QUOTE ] What would be the best way to set up my Redding Type S f/L bushing die. I have read a few things about setting the shoulder back 1 thou for bolt actions. OK easy enough, but after measuring my brass with a stoney point headspace guage I show the sizes to be different Headspace wise. Some of the brass is 1-1.5 thou different than each other. Is this because the cases are not yet formed to the chamber? Sinclair says to neck size only until after the 2 or 3rd firing. Is that the case? I guess I should just keep firing new brass till I get a good amount of fired stuff...then worry about it? Any help would be great Joe [/ QUOTE ] FORGET NECKSIZING! run it in the FL die till you get 0.001-2 bump on the shoulder -- then they will ALL be the same ALL the time! Your different measurements may be technique, because 50KPSI should have formed those cases [img]/ubbthreads/images/graemlins/wink.gif[/img] -- also may be crud/goop on the bearing surfaces of the tool -- take the lowest reading and subtract 1 thou from it -- set up you FL die to HIT that number Redding's comp shellholder set makes this easy [img]/ubbthreads/images/graemlins/wink.gif[/img] JB [/ QUOTE ] Great post JB. When you size the cases with the FL die it will force the shoulder up and then set them all back exactly the same, even if there is a slight variation in them this time for some reason. Keep your die up so it doesn't touch the shoulder on the first one and measure to the shoulder to see how much it increased in length when sizing then screw the die down 1/16 to 1/8 of a turn at a time and keep measuring and checking it in the chamber until the bolt just closes. The end measurement will most likely be .001 - .002 back from your longest fired cases and your die is properly setup. Like JB said, they will be the same EVERY time you fire them now. [/QUOTE]
