How do you read the RCBS Precision Mic?
I realize i am opening myself up to sounding like an idiot but i can not for the life of me figure out how to read this thing. There is no way it is giving an actual measurement. Based off what i see, my head space is 0.001? What the sam hill kind of measurement is that?
In the instructions, i understand what they say each line on each piece represents (i think) but what do the numbers represent? They make absolutely no sense to me. Why the heck is there a line below "0" on the body? Zero is zero! I will gladly accept an idiot joke if someone can help me make sense of this thing.
