Sierra lists the BCs for the 165 TGK as G1: .530 and G7: .234, which seems off. If the G1 is .530, shouldn’t the G7 be higher? For example, the G1 of the TMK is .535 and the G7 is .267. When I plug the two TGK BCs into a calculator, it results in about 100 FPS difference at 500 yds from typical .308 MV. Is this a mistake by Sierra or am I missing something?
