MY experience/use: 85-100gr, IMR 4350 always. Good argument for 4831, RL22, 7828 in longer bbls for 100s, higher speeds if you want them.
60gr, H414 VERY accurate + fast.
70gr Varget VERY accurate + fast.
Federal brass is GREAT, WW should be about as good. Lapua best.
Southtexas, +1, 4320 meters great, often overlooked powder, my GO TO for 338/06 loads in former rifle. Should be perfect for 85-87s and very good also in 100s.
