[QUOTE="Wild_Bill, post: 1996023, member: 4785"] Sorry your gunsmith is incorrect. Ackley chsmbers are supposed to be .004" tighter. That is why some people use the standard GO guage as a no Go. The reason is that cases are always slightly shorter to the shoulder datum ned before firing and by tightening the headspace .004" it allows the case to have a slight crush or interference fit. If you use standard guages you are basically setting your headspace to Field tolerances [/QUOTE]
