[QUOTE="boomtube, post: 288016, member: 9215"] Using the chamber itself as a sizing gage is perhaps the best and certainly the cheapest way to properly set a sizer. Basically the way Ridge suggests, but ... the total range of "normal" headspace, minimum to maximum, is something like .007". One eight turn of a size die moves it almost exactly .0089", about 2 full thou over the total headspace allowance. That's too much! Suggest that once you get any sizer close limit your adjustments to one sixteenth turn (4.5 thou). Preferably a bit less if you really want the cases to fit without stretching when fired. [/QUOTE]
