My micrometer is not what I would call a quality, precision instrument. I do not have a ball micrometer but I do have a nice set of Mitutoyo calipers.
My question is, can I measure the thickness of my case neck using my calipers, factor in the bullet diameter to quantify my OD and accurately set my neck tension from that?
Such as the Peterson brass for my .280 has been no thinner than .015 so:
.015 + .015 + .284 = .314
Based on that I should be able to use a .312 neck bushing and achieve .002 neck tension.
Will this work?
