Yep Boxer, it's something I've thought about, but, as Jordan says, I shoot another load in the rifle that works perfectly for drop when inputting the correct velocity as taken from the chronograph. The scope's not the problem, unless it took a schitt after the last time I shot the proven load.
I shoot a 70 gr BT at 3725 fps and Ballistic's output is right on the money.
The bullet seems to be plenty stable as evidenced by nice holes even at long range.
The bottom line is that when I put 2725 in for velocity instead of the actual measured velocity of 3059, the drops match actual shooting. I've never had this problem to this extreme with any of the other profiles in Ballistic that I've set up (8). I forgot to note that when I shot the .264 WM, the dope was perfect.
I'm going to have to re-Chrono the load, but there's no way it's going that slow. Something else is going on. I'll also put the scope on my gunsmith's board and check tracking and click values.
