My comp days are over. Spine issues and evil wife #2 brought that to a screeching halt. Except for some IPSC in the late 80's all my match shooting was NMC and HP LR. The across the course stuff was all FL sized, pushing the shoulder back as little as possible but still allowing easy chambering. I tried just neck sizing the LR stuff but the loads I was using barely went back in so annealing and min shoulder bump worked best for me.
Personally, at least in sling shooting, range time with good loads gained better scores over time spent wearing out barrels trying to find perfect loads.
Don't know my azz from a hole in the ground about bench rest.
