The way you are doing it is as good as any. Once you have the over all dimension for the smoked case, load ten rounds or so and fire for group. Then back the bullet in 5-10 thousands and try again. Each rifle is different and will like a different setting. On some rifles the magazine overall length will limit the loaded cartridge length. Some bullets like to be jammed a few thousands and some like to jump 20-30 thousands. It's all magic and there is no set numbers to work with.

I was going through that with my .06. So I bought one of them RCBS precision mic gauges. its got every thing you need. I now can set my depth to 0.0005 if I want to (yes .0005) http://www.rcbs.com/downloads/instructions/PrecisionMic.pdf got to get one for my 7RM noe. But thay are kinda of spendy $65.00 but worth it
