As I said my chrono may not be reading correct but in saying that some loads I have chrono in other rifles and then validated the drop have been pretty close, so reasonably confident it is good info I am getting.
My load is with the 178gr ELDX with 58 grs SF and the COAL is 84 mm.
I have two chrono's so I might line them both up so I can get a reading of the same shot over two different chrono's, one is a F1 Chrono the other a Pro Chrono plus.
I tried this with some 223 loads and got readings between 10 and 50 fps between the two units for the same loads. Might give it a go with the 30 06.
