Just to muddy the water a bit, I have a TC Dimension 204 barrel that shoots very well(Sierra 39 gr) with the 0.007 sizing that my fl sizer squeezed brass to( with no expander). That die I have to use a mandrel on the brass, when I run other brands of bullets. I have since picked up a competition die set that works the brass much less, and still shoots as well.
