If you google shooter app manual you will find a manual online.

In an earlier posting I said this was needed for Coriolis Effect which is not correct. In actual fact it is used for Spin Drift. If you wish to use Spin Drift you need to enter this data and turn Spin Drift on. I don't bother using it for closer ranges and usually enter my barrel twist because I know that off the top of my head, but don't bother with projectile length. If I remember correctly, from the old 303 target shooting days the correction was something like 1.5 MOA at 900 yds. Should run it thru Shooter I suppose :-)
