[QUOTE="Gene, post: 945414, member: 7402"] Be very careful of using the "cam over" sizing method. It can push the shoulder back excessively, resulting in too much headspace and a FTF. I use Redding micrometer dies for seating. First I know where my bullet will kiss the lands. Then I decide where I want them seated: how many thous in or out, write it down. I set the micrometer about .010" higher than desired, measured with a Hornady or Davidson comparator (I prefer the latter). My loading block is numbered on the side from 1 to 10, meaning thous over. I seat bullets 10 at a time, and place each in the block according to how many thous I must reduce the OAL. From that point on its easy to hit the desired length right on. [/QUOTE]
