have you tried SAC comparators? They fit the entire shoulder, caliber specific. Is that one of the comparators you are referencing? Considering lube on the shoulder will cause abnormal bump...I get the imperfect/ unclean statement.View attachment 1411280The outer surface of these cases are not perfect, when I use a comparator that covers the shoulder I can get minor variations whereas if I use a comparator that datum’s off the mid shoulder ( in my case I use a Hornday .30 insert) and keep the mating surface clean the amount of variations is quite minimal.
