Park Falls, WI. Nov 5, 2013. #1. Years ago I when I was on the search for a decent free external ballistics program for the PC, I came across WinBal (Windows Ballistics) and was wondering if anyone else is familiar with this program. If not, I think you can still find it online somewhere- just Google WinBal.zip and you should be able to find it.Table 6 compares Nosler and Litz BCs for the Ballistic Tip to determine the average overestimate which is 6.33%. The Nosler 120 grain NBT in .284 had the highest overestimate at 12.7%, with the 115 grain .257 NBT and the 125 grain .308 NBT also having substantial overestimates at 10.76% and 9.58%, respectively.It's also much more.

What is the Coriolis Effect and How Does it Affect Shooting? When talking about ballistics, the Coriolis Effect refers to the deflection on the trajectory of the bullet generated by the spinning motion of the Earth. Its effect is negligible at medium distances, but becomes important around 1000yds and beyond, especially because it can add to other minimal errors and keep you off target.

Drag/Twist. Calculate drag and stability from bullet dimensions, weight, specific gravity and barrel twist.Ballistic coefficient facts. In ballistics, the ballistic coefficient (BC) of a bullet is a measure of its ability to overcome air resistance in flight. A high BC means the object will slow down less. It will have more of its speed left when it reaches the target. BC depends on mass, diameter, and drag coefficient.
