All, I understand overall length, case mouth seating, proximaty to rifling much better. I am going to order the bullet seating plug from Lee. I am convinced that is the cause of the inconsistency. I checked the fit of the round in my EDC. Someday I will measure to the start of the rifling and determine my personal OAL for the round/gun combination. Someday.

In the meantime, I am going to adjust out to around 1.130 to 1.135 and rock on.

Thanks for all the input. It makes an interesting read!
