Range Report Spin drift on Ballistic!

[mdmp5]

Is it just me, or does Ballistic (on iPhone) give the opposite solution for spin drift? FOr example, if I enter a positive (RH) 1 in 12 twist, it spits out a correction to dial the POI to the right. I was expecting the clicks to be shown negative, or to the left. Or am I just really dumb today?

I don't think its giving you the correction, but rather where the bullet will go. I thought it odd about Ballistic too, until I figured it wasn't telling me where to adjust the scope but instead telling me where the bullet is going in relation to your zero. Its kinda ass-backwards but you just do the opposite of what it gives you when dialing your windage or elevation.

Just out of curiousity, are you using the JBM engine? I get the exact same results using that as with the online version of JBM.

3000 yd or 1000 lines in the drop table, whichever comes first.
