[QUOTE="Kentucky, post: 1629239, member: 86585"] Hey folks, another head scratcher for me. I have used a comparator for my sizing for along time and never blew myself up. I was recently introduced to head spacing using the RCBS Precision Mic. I could t wait to use it on some already sized 22-250 bras. To my surprise I had .010 - .012 variances. I set up and sized more brass, measuring each one and low and behold, I cannot keep my size consistent. One will be +.005 and the very next one may be -.005. I am hoeing RCBS ram with Hornady dies. My Buddy was doing the same and decided to buy precision shell holders. His are now precise consistently. Can anyone explain to me why the shell holders would make such a dramatic difference?
