[QUOTE="65WSM, post: 1634377, member: 9551"] I use the K&M expanders often to get the neck tension I desire. If I have turned the necks on the cases, I often get more consistant neck tension, measured with the K&M dial indicator on their arbor press, with expanders than I do with outside neck bushings. Full length size dies usually produce 4 thousandths under bullet diameter. I like to have 1.5 to 2 thousandths and the K&M expanders will deliver that. I use the Sinclair die and expanders too, on occasion, to get similar neck tension. The Wilson bushings are another tool that deserves mention. The bushings are tapered inside half a thousanth. If you turn them around, then you can get a half of a thousandth of neck tension. Consistant neck tension is second only to consistant seating depth in long range accuracy.
