[QUOTE="tlk, post: 278020, member: 11397"] OK, I think I found a problem: If the brass is f/l sized as stated before and everything is centered, neck is turned, etc., what happens to the brass upon firing? Will the thin portions of the case body expand faster than the thicker and cause the case to swell into the chamber at an uneven rate around the case body? If so, will this cause the bullet to no longer be aligned by the time pressure has built up enough to get it out of the case and into the barrel? Is the case thickness variation causing innacuracy in this case? Somewhat difficult to explain what I am talking about, but I am thinking that the uneven expansion might have an effect by placing leveraging force on the shoulder/case mouth. But would it? Would it matter if you had the case body smaller than the chamber and the whole case pinned between a trued boltface and the datum? I wonder with this being the situation if the shoulder being a slight crush fit would help prevent/minimize this issue. [/QUOTE]
