OK, so now I got my LabRadar and decided to use Ballistic Coefficient as a means to finding the right speed for a given projectile at a given range. The LabRadar gives me all the velocity data I need but it doesn't calculate the BC at any given distance.
So, being the clever girl I am, I went searching for a excel formula, or spreadsheet that would do this for me. What I found is making my head hurt (yeah, I'm a blonde).
Apparently there is something called a Drag Coefficient (CD) which maybe more accurate than the BC, and is what militaries use.This is not the Drag Law (G1, G2...etc) that we enter into our favorite airgun ballistic programs.
So, I'm guessing someone smarter than me has developed a spreadsheet, or database program that would do both from the data imported from a excel .csv file that I get with LabRadar. Failing that, perhaps someone has the formulas formatted so I can drop them into a Excel spreadsheet.
I'm thinking that "Yrrah" has done this, but it looks like he hasn't been around in a while.
Any ideas?
