I just bought a S&B 5-45x56 with 0.5CM elevation and windage. Also, bought a Kestrel 5700x and set up my rifle profile. For the EUnits and WUnits, I have multiple options, including CM or Mil. What I am hoping to get is the Kestrel to tell me how many clicks to adjust in relationship to my 0.5CM per click turrets.

I put in my bullet data in JBM and I believe I have it calculated correctly, but I can't get the same readout on my Kestrel.

Here is the input data:

1000-150.7-150.70.00.01567.61.404600.11.4040.00.0

The Kestrel has me at 72.7 mil drops, which if I double to account for 0.05 mil per click, I'm still not getting the same 1000 yard drop clicks.(72 X 2 = 144 whereas JBM has it at 150.7). It gets rather close the closer I get so maybe this thing is calculating it correctly, just a little bit of variance?

I appreciate the help.

What does the bullet tell you? Don’t worry what any BC calculator says until you have real dope. You make the software match the real world data not the other way around

That's a good question. I haven't gotten an opportunity to test it yet. Will try it this weekend and see where it ends up.

I guess to save ammo, does the drop clicks above seem about "normal" or is it significantly different? I don't want to overshoot the berm so much I get asked to leave the range :)
