[QUOTE="br45zy, post: 1157663, member: 67266"] The easiest and most accurate way to determine what bushing you need is to measure the thickness of the brass at the neck with a ball micrometer. Double that dimension then add the caliber dimension (.264"). Depending on the neck tension you want want select a bushing .002" or .003" smaller than that result. It's not as accurate but you can also measure the outside neck dimension of several loaded rounds then take the average value and use that to select a bushing based on the neck tension you want. Hope this helps [/QUOTE]
