I use a F/L die and do the PFLR thing. I do not bump the shoulders back and, in fact, only resize about 75-80 percent of the neck. After a couple of firings, this forms a small doughnut around the neck at the junction with the shoulder. I feel that helps to align the cartridge in the chamber. After several reloadings, I usually need to F/L resize the brass and start over.
My hunting ammo is usually 1X and I cycle every round through the rifle to ensure that it will work flawlessly before I go hunting.
