It is a simple neck down. I haven't been getting any pressure signs other than some light primer crater and slight flattening. Like it says in the spreadsheet, some of the loads might be max and work your way up. They functioned safely in my rifle but not all of those are loads I will shoot everyday.
Not my picture, but the third from the left is the worst I've seen with my reloads and not commonly seen. The BHW poly rifling is known to reduce pressures across the board. I have reloaded hot loads up to 5x in the sane brass with no issues.
