LBJ,
How do I verify this? I use a combination of comparing my beloved "Shooter" app, the 3200.com dope and the Kestrel dope. Initially, I input all the data I can, into all 3 devices, while at the range, zeroing the rifle at 200 yds while shooting over my Labradar. I then shoot onto paper, 5-shot groups, at 1000 yds. In the past i've trued my velocity to match the moa adjustments to get solid center hits. This last time, instead, I adjusted my BC to get solid center hits. I needed to move my published BC of G1 .633 to .615 (.5 moa). I then adjusted the BC in the Shooter app, 3200.com and Kestrel, all to .615. Just now, in the dark I can range the hill behind my house at various distances out to sub 1000 yds. In spot I can consistently get 874/5 yds. I keep doing this using just the 3200.com's, (18.3 moa), Shooter (18.3 moa) and Kestrel (18.6 moa). That's a 2.6" difference at 874/5 yds.
Is this what you're inquiring about?

Hi Alan,
You've got all three of your devices calibrated with respect to each other at your current location for the same atmospheric conditions. Really impressive job by the way. Although you might try using the Custom ballistic profiles in the Kestrel as the benchmark and adjust the BC's in the 3200.com and Shooter to match it the next time you go through the process. I only suggest this because I've used several of the AB Custom ballistic profiles in the Kestrel and they have ALL been spot on out to 1000 yards or so.
Now that you're 3200.com and Kestrel are calibrated in Utah (I'm guessing elevation about 7500' and DA maybe about 5500' to 9500' depending on the day), book a trip to Florida, Texas, even California and take the Leica's and Kestrel with you. Range some "targets" with the Leica and see if its solution matches the Kestrel. The Kestrel being fundamentally a weather meter will tell you the correct ballistic solution. In other words the Kestrel is the benchmark. Then, just see if the Leica solution matches the Kestrel to the same, or similar, accuracy it did in Utah. This is essentially what I did. When I got home (actual elevation about 700') from Utah last September. I compared the Leica's to the Kestrel and there was a significant difference. I didn't write the numbers down but I remember the difference being enough for me to question the atmospheric measurements/integration of the Leica's.
