If you turn case necks, and try to hold wall thickness variation to half a thousandth or less, here's a superior tool. Sinclair's Digital Case Neck Micrometer measures neck thickness to ″ on all calibers from .17 all the way up to .50 BMG. The unit powers up (and zeros) at the touch of a button, and a large friction barrel makes it easy to adjust the contact pressure or "feel".

As a system, the Holland Mic and Base comprise a nice setup for around Tubing Micrometers. If you don't have a ball micrometer, a tube micrometer can also be used to measure case neck wall thickness. Tube micrometers (tubing mics) are widely used in industry to gauge the thickess of tubing sidewalls.

To support the walls during thin wall milling, keep a widecross section behind it. We recommend utilizing a "stepped down" approach, which divides the total wall height to manageable depths while working each side of the wall. The Axial Depth of Cut (ADOC) dimension will vary depending on the material (and its hardness) being cut.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
