Sometimes I do as the manual says and give it just a little room to self center.
But most of the times, I back it off and only size a portion of the neck. That way the unsized portion of the cartridge neck centers the round in my chamber. That has worked for me in my rifles, but I'm sure there are exceptions.
Beware, that too little neck tension can be bad, if you keep rounds in a magazine on a heavy recoiling rifle they can move.
I'd say on average, I leave 25% of the neck unsized. I use good brass that is very consistent thickness, I don't know how this would work with poor brass.
I also adjust the FL portion to just bump the shoulder back .001" or .0015", as I don't share reloads across my rifles, they each have their own brass.
I also throw the lock ring that comes with the Redding dies in the trash. I use the Lyman split rings , as they don't mark up the threads and they seem to be pretty straight.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
