[QUOTE="Trnelson, post: 1230688, member: 42308"] Here is how I calculate neck thickness...0.295 - 0.264 = 0.031 / 2 = 0.0155" wall thickness of your brass, in the loaded configuration. 0.295" allows for 0.001" all around the outside of the case once fired, IF your chamber neck is cut 0.297" which is to the minimum side of chamber spec. Your neck bushing is 0.293 so you have decent neck tension. I wouldn't change that just yet. I would look to ream that brass a bit. I would start by taking it to 0.015" that will give you an additional 0.001" total clearance. That will allow the brass to expand and spring back normally. It's still a little to what I consider to be the snug side of things, but you can work with it as long as you know what you have and build your rounds accordingly. Good posting. [/QUOTE]
