Keep in mind that these dies were designed for match/bench chambers with close fitting necks. That is why they recommend bushings that are 0.002" smaller than loaded neck diameter. With hunting chambers, the fired neck will be quite a bit larger, so there needs to be some trial and error, because a bushing that is 0.002" under may size the neck way too much.
Pay particular attention to the second to last paragraph that starts with, "... it has come to our attention through customer calls and our own use of the bushing style sizing dies that in certain instances,".
