Update: I was out with Zach O yesterday shooting Target out to 165. It was impacting 0.6 mils high based on dope generated with a BC of 0.105. We checked every input for an error, and found none. Now I'm suspicious that the published value is a misprint and the BC is really 0.15 like everything else. If I put that BC in and increase the speed just a few FPS the dope matches the data we collected.

If I have time this weekend I'm going to chrono that ammo out of that rifle with a magneto speed. Last time I used a crappy Shooting Chrony, and I don't trust the results.

Once we figured out the dope, the ammo shot great in a match.
