I think I got it figured out a bit better. Been playing with it for the afternoon and discovered some things.
1) repeatable, consistent technique is a big factor
2)make sure there isn’t dust/crap in the comparator insert that won’t even let the bullet sit in the collar straight. [emoji1787][emoji1787]
Once I pulled the dust/crap/bullet shaving particles out of the comparator collar on my caliper my numbers tightened up.
Did it a handful of times with two different bullets (from the same lot) and took averages. Looks a lot better. Anyone else have any tips or tricks to go with these tools?
