I'm not much into tech stuff, I don't own Scopeknob, nor how it works. I occasionally use Chairgun, if I'm pressed for time, and even at that, it's just to get a ballpark starting point. In general, I don't use, nor depend on them, all my marks on my turret, I actually shoot. I found that the data doing it real time, much more accurate than a lot of programs out there. I own Ray Apelles program, and many people swear by it, but I haven't really tinkered with it enough in order to be useful to me at the moment. Maybe that I'm snowed in here in the Northeast, I might get to it.
You might want to ask this question on a new headline thread, I'm pretty sure there are MUCH more qualified individuals than me that can steer you to, or create an instructional video on it. I'd watch it as well!!!
