Re: How much to turn necks?
Id bank on .342" I wouldn't feel at all uncomfortable in turing them to clean up if youre using a bushing die, or the lee collet die. If I was going to use an expander on these cass id turn them to clean up 50%. Expansion will be about the most id want to see, but you shouldn't have any trouble with necks splitting too fast. Im loading for a7mmREM mag that has .009" total expansion on firing, and the cases are lasting well. ive got 3 cases that are at their 7th loading, and the other 150 are at the 4th loading with no signs of problems... comprable dimensions to your setup if you turned them to full cleanup, more or less. For those that think .002" per side is too tight to come from a factory chamber... it ain't. A number of savage barrels ive worked with, and at least 2 remingtons recently have had .005" total clerance or less. One savage with federal brass .016" neck thickness, had .003" total.
