I picked up a RCBS Precision Mic Gauge. I fully understand the headspace "half" of the tool, but I do not fully understand the seating depth "half" of the tool.
According to the instructions, you (1) set the freebore tool to a specified length (done). Then you (2) chamber the freebore tool (done). Then you (3) measure the freebore tool and record the new length (done). How does that then translate to a seating depth? The best I can figure is that you make a dummy round and then measure it in the gauge and make adjustments to your seater die until you get the desired depth - something like whatever your measurement is in step 3 minus 0.010" as measured in the gauge. Is that correct? You basically keep adjusting your seater die, seat your dummy round, and then put it in the gauge?
The directions are not very clear on the last part.
Thanks!
