Then I used my OAL gauge in the chamber and measured case base to ogive with each bullet, and got .030" difference, CONSISTENTLY. ( 2.050 & 2.080 )
I repeated each measurement 3 times.
I can't figure out why the difference. If there's a .002" difference in the bullets themselves, shouldn't that equate to a .002" difference in the assembled round?
