[QUOTE="eklarsen, post: 1329278, member: 93902"] You should typically have .003 - .004 gap between your reamed chamber and your brass neck. If you are shooting a .308 variety, the bullet is .308, then measure your brass thickness, for example .016 multiply that times 2 (both sides) that equals .032, add that to the bullet diameter and that nets out to .340. That would be perfect if your chamber was .343 - .344 and that is the fundamental measurement. The neck sizing bushing is for sizing for the correct neck tension, that is why folks suggest to measure your OD then minus .002 -.003. that will apply that amount of tension to hold the bullet in the case but you have to get the brass neck size correct first before you take that measurement. I hope that makes sense. [/QUOTE]
