    Martin,
    It depends on when I'm turning the necks. If its with virgin brass that the first expansion is going to be of several thousands because the necks are thicker and a lot of brass is removed on the first pass. After the first time the expansion is reduced because the necks walls are close to my target (.013) and only new brass that has moved in the neck is being removed so the expansion is generally less .001. That's the idea of calibrating/adjusting your bushing to compliment the mandrel so that the brass is not being moved a lot and is only used for fine tuning.

    Paul,
    Its a machine shop, so they don't have "Products" like a store. Email/call Kenny Porter and he will give you specific answers to specific questions.

    Are you are asking me this question? Or is it for the forum in general?

    Steel media or brass brush would do it.

    Joe, that's why I feel it's best to index off the shoulders when trimming necks. Then, the stop for the neck turner (case mouth) should be the exact same distance from every shoulder, and produce the same depth of cut into every shoulder.
