Just released Gun Log version 2.5

The Gun Log Blog specifies the release details.

What's New in Version 2.5

Bullet Drop Estimator. In a Firing Set or from a Report the bullet drop can be estimated. In a weapon's configuration specify the sight height in inches above the bore axis and the zero range in yards. In the ammo's details specify the ballistic coefficient (typically a number between .2 and 1.0) and the muzzle velocity. With that data a "drop table" can be calculated that estimates the bullet's vertical position and time of flight. The calculations are based on the G1 ballistic coefficient with the standard assumptions of sea level and other variables.
