You can use the 175 SMK and the FGMM brass to mimic the Mk 316 Mod 0 cartridge. Add 41.7-41.8 grains of IMR 4064 lit by a Federal 210M and watch the little groups appear.
Yes sir, my only difference is mine all roll at 42.2 but I have not found a .308 that did not shoot tight groups with this combo!
