I have been searching/reading about making drop cards with DA, and I have made myself a "Barney style" checklist to work some up. I need to know if I an missing something before I get started. I dont have any sort of PDA, but I do have a kestrel, thats why I am interested in making these drop cards.
1. Get info from my specific load on how it acts at different temperatures and form a sort of temp vs. muzzle velocity ladder to have good #'s to put into the ballistics program.
2. Work up some different weather scenerios for my part of the world using temp,hum.,station psi
3. Plug these scenerios into the DA calculator that Lindy provided in one of his articles to get DA values for each one.
4. Use the same scenerios entered in my ballastics program to get drop values.
5. Make drop cards with DA values referenced to the drop values.
6. Use the kestrel in the field to get a DA reading and refer to the cards.
I read in Lindy's article that you have to be sure that the measuring device you are using is calculating DA the same way that the DA calculator is. Does anyone know if the kestrel 4000NV calculates DA correctly?
MUCH OBLIGED
