I FLS and shoulder bump the norm. But the thing i know i should try but havent is to leave the necks un-trimmed and no de-burr inside or out. I heard a rumour this results in lower ES... i hope this is wrong. Seriously.

Hard to fathom. No internal deburring with produce variably scratched projectiles which can't help. No neck trimming will eventually lead to projectile crimping that will up pressures. Who would want to go there?
I have become "a less is more reloader".
After making the brass initially
Originally I would clean, trim, chamfer, anneal, neck turn, ream inside necks, neck size and body die when necessary, clean primer pockets and hand prime, weigh every charge twice blah blah blah.
Got 13+ reloads out of last 50 new brass and still going.
Goal was 3 consecutive hits on a 4 inch wide x 6 inch high plate @ 1005m consistently ie each visit.
New barrel and new brass and after initial case forming (6.5SAUM or GAP if you prefer)
Anneal every 5 loads, clean brass full lenght size and load. Same goal and was achieved so now I don't bother with all the fannying about.
I trim when necessary
I guess if trying to get them thru the same whole it would be different.
For my 6.5TCU I load on the RL550B, I dry lube the inside necks of 223 brass, lube the cases well and neck it up on the first stage with the FL Die and loaded rounds come off the shell plate.
3 consecutive hits on a 4 inch plate at 535m was/is the goal.
Less time loading and more time shooting, whats not to like :D
