I have seen a bunch of new programs come out but not one where you just plug in the density altitude. Why not? would it not be as accurate? Is there a BP where you just plug in your DA from a weather station?
 
Re: Ballistic program w/ DA

Density altitude is calculated from atmospheric pressure, temperature, and humidity. If you have a device which calculates DA, it also measures those quantities, which can be plugged into any ballistic program.

In other words, there's no real reason to have a program which will take a DA input.

In addition, muzzle velocity is a function of temperature, which several ballistic programs will compensate for. So, you need the temperature input separately, so you might just as well enter the pressure and humidity.
