[QUOTE="Mikecr, post: 1302617, member: 1521"] With enough neck turning experience you'll come to learn that settings are relatively dimensionless, as the correct settings are always relative to more than the tool itself. That being the necks themselves(thickness,hardness), their mandrel fit, lube, cutting sharpness and cut amount and turn & feed speeds. It's like any & every sizing for target dimensions. A die alone does not dictate results here, as all is tied to the brass itself. So none is predictable, much less set with a dial. There will always be a bit of trial & error testing/measuring to sneak into desired. For turning, my beginning ball park setting is simply done with a feeler gage between the cutter & mandrel. If a first trial cut needs another 1/4thou, it should, I started a bit shallow, then I adjust the cutter another 1/4thou with another feeler gage. This was done with a few cases culled due to some departure from the pack, and within a few tweaks I'm typically dead nuts perfect. Then I go to my good brass. Takes but a few minutes whether cheapest or most expensive turning system, for any prepared cartridge you want to turn at the moment. Over the years I've used K&M, then Sinclair 1000, and presently Sinclair 4000. Neil Jones lathe. The Sinclair systems originated from someone at PMA. They're well thought out and make turning very easy to do well. While I love K&M tools, I do not prefer their turning system. [/QUOTE]
