With regards to brass life, assuming proper reloading techniques for minimal shoulder bump and good case annealing etc., is there an optimal neck thickness for longevity? Or is it "thicker the better"?
Obviously thicknesses vary by brand and by lot, and I have seen anyway from .013-.018" on factory or military brass. I've read about folks turning down as far as .010".
I am new to turning in general, but understand the value of consistent neck tension. I began using bushing dies for my match rifles and Lapua brass, and the results are very noticeable. I am now thinking about working on some of my more obscure hunting rifles, but with component availability not improving any time soon, I want to make a well informed decision before I cut.
In this case, its my namesake, 257 Roberts. I have plenty of Winchester +P brass, and it varies anywhere from .015-.0165. I have a 0.284 bushing and was planning to turn to .014" for a .001" neck tension. Is .014" neck wall thickness realistic, or is that too much or too little?
I am sure there are varying opinions on the matter, and all opinions are appreciated. Again, while I am trying to clean up my reloads for better groups, my goal is brass longevity.
Thanks as always.
