Thanks all.....
It's probably more attention to details than actual load work, although that's a big part as well.
A few thoughts come to mind.....
I anneal every time, I use Wilson inline bullet seaters, I always seat in the lands, I check & straighten every round.
This brass, I FL sized out of the box, deburred/beveled flash holes, annealed, neck turned, necked down, turned again, neck sized, and annealed again prior to loading for the 1st time.
