B-Rad,
When trying to achieve the accuracy you are going for, when you change one
Verbal everything can/will go to crap. In other words, You will literally be starting over.
Remember that the Lake City brass has less internal volume and the Mag primer can add as much
As 1 grain in performance/pressure. Right off the bat, that is a 2 grain reduction from where you are at now.
(Just to be safe), then work your way back up….(Starting Over)
