Trying to calibrate my ballistics app but can't find the BC of the 155gr bullet or listed velocity of this ammo anywhere.
Anyone have it?
Thanks

Re: RWS .308Win 155gr (NRA Target) Ammo
they were Sierra 2155's weren't they ? (I assume this is old stock as the new NRA match is GGG, I don't know if they still use the 2155, or if they have changed to the 2156)
Re: RWS .308Win 155gr (NRA Target) Ammo
Still the old Sierra #2155 I believe. That makes its average G1 BC 0.417 and G7 metric 0.214 (Bryan Litz).
