I'm no expert but I have seen a lot of people doing different things in those years. I have my ways of doing this that seems to work well but I might learn something from the guys doing it 10+ to 30+ years already. They might share one tool or method here that changes the way I look at the subject.
I wasn't real sure which forum it should go on but fiqured elr would be the right one as were discussing how to correct for shot that can be as long as you feel comfortable. If they move it my feelings wont be hurt lol.
I primarily use two methods to determine air density and wind corrections; a computer and firing tables.
For both the computer and tables I have learned to love using a Density Altitude air density equivalent for corrections. The Kestrel 4500 will take your temperature, Baro, humidity, and altitude and convert this data to a Density Altitude equivalent. I have found it much easier to use a ballistics application that will take DA to determine the air density and apply this to the program. Only one input vs. many. Simple is smart.
I also print my tables for every 1000 ft change in Density Altitude. As I hunt thru the day, I take out the appropriate DA table for the current environmental conditions. For example, 0 ft DA, 1000 DA, 2000 DA etc. Look at your Kestrel every now and then. If it says 3220 DA, I pull out my 3000 table and place it in my back pocket. I will change as conditions change throughout the day. I have found every 1000 change is sufficient and rounding to the nearest 1000 will provide the elevation correction results you need without too much of an error.
Now itís the wind uncertainty that predominately limits maximum hunting range. On my tables I will color code the ranges with high, medium and low wind confidence with green, yellow and red highlights. These are my maximum ranges based on uncertainty to within a 1 MPH full value cross wind (green), 2 MPH uncertainty (yellow), and 3 MPH uncertainty (red). If uncertainty is more than 3 MPH Iím not shooting past 400 yards period and most likely even closer.
Primarily I will use a computer for ballistics solutions, then validate off my tables. Garbage in on a computer equals garbage out. Anyone can have sticky fingers now and then. The tables validate the firing solution.
Hope this helps and good shooting.
