I've been trying to get various ballistic solver apps (iphone apps and JBM website) to come up with a BC that matches what I get in the field. The goofy part is that it seems the BC needs to be banded and needs to be higher as distance increases (to a point, I assume). In other words, the basic BC solutions have been giving too much drop past about 100 yards. And this is subsonic ammo, there is no transition from supersonic to subsonic as it flies. I am curious if anyone can comment on why 22LR subsonic seems to act this way (stability? yaw?), and how I would go about building a BC that solvers can use to accurately (-ish) model my dope. Thanks! Apologies if someone has covered this and I missed it.
