Went through the 308 load data section, never found these bullets mentioned. Saw alot about 200.20, 208, 185 jugs, and 178eldm, though. Anyone using these in a 308 or are they no good? Will be in a 20" 10tw ai, lapua brass and cci200 with imr 4064, or am I better off going with a 175smk/tmk or 178 eldm?
