Thread: trajectory validation distance

When validating or truing you go to where your projectile goes into transonic and shoot to with in ten percent of that distance.
If you want to shoot past that you then get into the system of DSF (drop scale factor)
which then allows for predicting trajectories through transonic and then into subsonic .
In the kestrel 5700 elite it puts a small dot next to your remaining velocity when you go into transonic and a bigger dot when you get to subsonic..
It sounds a bit technical but quite simple once you've got a handle on it .
The 5700 also will give you a suggested distance to true at .
Todd and colby hodnett do some great tutorials on this that are worth watching.
If your serious about longrange get a kestrel 5700 elite, the one tool I never leave behind.
