I'm curious about this exact setup. I'm pretty green with LR shooting/hunting but have been playing around with Strelok Pro for a couple years now. I know I need to input more data into the app itself (velocities at different temps, etc.) but I've had issues with the app being slightly off per recommended MOA adjustments at a given distance. I'm wondering if this device paired with Strelok Pro app will help close that gap and give me more precise adjustments from the start.
Environmental conditions in the ballistic predictors will help. The Kestrel Drop and Ballistic Arc's enviro systems work well to get accurate drop and wind deflection.
But, every gun shoots bullets differently affecting the BC. You will need to "true" the solver to your actual data. Shoot several ranges and record all the inputs. Then, tweak the ballistic inputs until it matches real life. There are many ways people say to do it, but change velocity out to 800 and BC beyond that until the predicted curve matches your actual curve. Make sure and get ALL the inputs accurately for best results.
The closest you can come is a personal drag model where Applied Ballistics actually radars your bullet shot from your rifle. That will predict across a wide range of variables.
Next is the custom drag model for a bullet by Applied Ballistics. I have found it to be very, very close. Often with no changes needed inside 800 to 900.
Hornady 4dof uses a reputedly good system for its bullets.
Streloc, Shooter, Ballistic Arc, they all use the same of very similar computer models. Streloc is very popular.
Kestrel, Sig, Vortex and other products with AB solvers built in give you custom drag models free.
