This is my first time loading virgin brass and my as-fired measurements are on the image file attached. Measurements fall between 1.5575 and 1.5560.
So, if I set my shoulder bump 2-thou off the smallest case they should all end up around 1.5540...Correct?
You’ll get a little variance potentially if you use too much lube as well. I personally usually fireform twice or three times till all the measurements are the same for a true fireform representation.
