You're there with 83.8 gr RL-33 beretzs, with confirmation groups too boot, the 3.535" load would be the stopping point for me, 175 grains at 3100 is gonna smack plenty hard for a bull elk out to 600 yards.
I may have a larger sizer ball in my die than you, I can barely get a .281" pin in, and with no donut feel, hope my 160 accubond load with 85 grs Rl-33 at 3258 will hang with the big 175's for odd angle heavy game shots should one arise, I may try some 175 Partitions to 3100 and see how my rifle likes em, I'm hoping it's gonna be tough to go wrong with any of the three bullets listed.
