The problem probably has more to do with strange things happening at extreme long range (for a .22 LR bullet) ballistically than anything to do with the Kestrel 5700
Same things happen at ELR with my center fires and really good bullets. It’s very rare to input data into a ballistic app and have it line up perfectly with actual drop WAY out there.
Things seem to get screwy past 1000 yards.
To try to true up the data, I always have to tweak velocity inputs. Sometimes BC inputs.
I have a couple working really well at all yardages out to 1800 yards. The Mashburn with the 195 Berger EOL working great!
