    Density Altitude Help Please

    I didn't read all the responses but Temp is still an extra variable in Ballistics programs even though it is also included in DA because we model air as an ideal gas. In an ideal gas the speed of sound is dependent solely on temperature and since these programs reference a table of drag...

    Dope shooting uphill - tell me why I'm wrong

    I think we are getting hung up on frames of reference. And yes, the (de)acceleration of the projectile due to gravity when fired up or down pales in comparison to the effects of drag. My .260 with whatever my last environmentals were goes from 2790fps to 1480fps over 1000yds with TOF of 1.48s...

    Dope shooting uphill - tell me why I'm wrong

    No worries! And again, you're right in that there is no component of gravity that acts other than directly down to the center of the earth. The only thing that changes is how we are looking at that vector. Like you said gravity doesn't care how we launched the bullet or even that it is moving...

    Dope shooting uphill - tell me why I'm wrong

    You're correct, and I probably have done a poor job of explaining. Gravity always points the same way, however when we are looking at an angle other than purely horizonal gravity points slightly towards or away from us. That component (towards or away) is really small with comparison to drag...

    Dope shooting uphill - tell me why I'm wrong

    @Baron23 I don't know how to explain it differently, sorry We are measuring deflection from our line of sight. That deflection due to gravity is maximum when our line of sight is level and gravity acts perpendicular to it. As soon as the angle of our line of sight changes the component of...

    Dope shooting uphill - tell me why I'm wrong

    In your hypothetical in a vacuum, gravity would only act perpendicular to the line of sight with the magnitude of the green arrow and back towards the shooter with the magnitude of the blue arrow. The blue and green components add together to form the red gravity vector. Keep in mind there...

    Dope shooting uphill - tell me why I'm wrong

    Our line of sight is our reference frame. The bullet doesn't really care where it is going, once it leaves the muzzle the forces acting on it are drag and gravity. We just have to figure out how these forces work in relation to our line of sight so that we can correct for it. Hope that helps...

    Dope shooting uphill - tell me why I'm wrong

    The acceleration due to gravity is a vector. When shooting uphill or downhill you have a component of that vector that is now parallel to your line of sight. The "less horizontal distance" isn't technically correct, but it serves to illustrate the point.

    This may be a really stupid question, but where did that screenshot come from? Did that come from said user or does this app share our position and target data?

    Genesis Ballistics Solutions--Android Now Available!!

    I'm looking forward to the "how to" material. So far I've been a bit confused, coming from Applied Ballistics, where you first set up your rifle information and then input different ammunition details. With genesis it seems you create 1 track for each rifle/ammo combo. I'm a bit confused as to...
