Here is a link for a pretty cool software. It has a good amount of saved powder, bullet and primers programmed in it. All you do is enter you load data and the bullets BC and FPS and it will give you flight path, wind drift, energy, trajectory and MOA. All in charts and graphs. Good fun and its free. They ask you to donate $10 which is worth it. And hey if your Occupying Wall Street, well you won this battle because it FREE. But I donated the $10 bucks so I don't have to wait the 10 seconds for the start up. http://www.huntingnut.com/index.php?name=pointblank Wanna kill these ads? We can help!
