Kestrel Truing

[DisplacedTexan]

Trying to true DSF and my kestrel wants me to true out to 2127 yards. One, this is ridiculous and two, I do not have the means to do this.

I tried truing it to 1180 yards but it did not change my calculations. At all. Wtf over.

AB Kestrels have 2 ways to true, MV for shots in the supersonic distances and DSF for shots in the trans-sonic distances. True MV for 1180 shots as you bullet does not slow down to trans-sonic until about 90% of 2127. The Kestrel knows the 1180 is too short for DSF true and is not accepting that entry.

I’ve been listening to Frank’s podcast and did what he suggested recently. 600 and in, tweak the MV to get your numbers lined up. If you have access to 800 and up tweak BC.
Joel from PRN put out a video about truing on the Kestrel. He did BC at 600 yards which is also fine.

So I just got done with Dog Valley. My BC to get hits is .350 G7 with a 110SMK @3030. Bc truing is not going to give me correct wind calls sadly.

BC is about elevation not wind. Wind calls are on you and using the kestrel properly to capture the wind.

@DocUSMCRetired care to chime in on this?

It’s only effect on wind is a better BC holds velocity longer but the wind call is still on you. The best BC Bullet in the world won’t help you if you can’t judge the wind. But you true the BC to get your trajectory correct not fix poor wind calls.

Above Mach 1.2 you want to true your MV (never use a distance as a set point for this because Mach 1.2 happens at different ranges for different setups/locations/etc...)

Below Mach 1.2 you want to adjust the DSF (Drop Scale Factor).

If you try to accomplish a DSF at too short a range, the Kestrel will not accept it.
