What would be the correct Native Drag Model for a .308dia 208 grain Hornady A-max when using the Ballistic FTE program on the Ipod Touch? I'm currently using G1, I know from experience that G7(VLD boat tail) is not correct. G5(Low Base Boat Tail) looks like it may be correct. I've only tried G7 and G1, and so far G1 seems closest to actual trajectory seen while engaging targets. Thanks in advance.
