Considering all other component (primer, case, and powder) measurements are all consistent, which measurement of the bullet do you consider to be more important in regards to accuracy. The bearing surface (ogive to ogive), whereas the difference in bearing surface equates to greater or less resistance, which will effect plus or minus the pressure and velocity, or base to ogive in regards to bullet jump, where this also effects pressure and velocity or both ? I know we are dealing with very minuscule measurements, i try for +- .001 with case measurements, +- .02 for powder and +- .0005 for bullet and seating depth measurements. Or am I (as a friend would say) wayyyy overthinking it........
