Seems like an awful lot to trim but if it works it works. I am more concerned with the thickness of the neck after the case is cut down. I think the answer was a couple of posts earlier about the type of brass and I do like Lake City. Have found that the odd stuff (S&B, PMP, etc.) tend to be in the 0.014" range and the Federal, LC, Win and RP closer to 0.011" which works great. I am certainly not a fan of turning necks, but cutting off .222 or .223 brass, sizing and trimming seems to work just fine.
