Tell you what, old bullets 15 thou off the lands shoot 1 moa and cases extract without the slightest difficulty. New bullets seated to the same depth are 30 thousands into the lands and I have to pry the bolt handle open
Pretty sure I'm not overthinking it
I'm positive you're not over thinking this. I have 6-700 of these on my bench - my 308 loves them. I've noticed 0.020 difference in mine. I changed the OAL to ensure the bullet ogive was the exact same distance from the L&G. It appears accuracy is similar. But - I noticed 0.030 difference in the Nosler Partition 180 cal. I tried to keep the ogive- rifling relationship the same but accuracy suffered. Could have been some difference in bullet concentricity between differing lots of bullets but accuracy changed.
I'd try to keep the ogive- relationship the same and see what happens. Let us know what you find. Look at the positive - you get more trigger time either confirming or developing a new load
