Physics and Firearms
                                          Physics Concepts and Theories of Shooting Firearms
When shooting firearms there are an infinite amount of variables, theories, and concepts that affect the way the bullet performs.  For this project I am using a 50 Grain Solid Base Ballistic Tip (yellow) .270 Caliber (.277") bullet shot from a Winchester rifle with a Shiten barrel that is 24" in length, with 52 grains of H 4350 gun powder.
Of the many theories and concepts the one that is the most used is Ballistic Coefficient.  While it is the most used, it is also the most confusing.  Ballistic Coefficient can be described as
C = Drag Deceleration of Standard Bullet / Drag Deceleration of Actual Bullet,
and can be mathematically described as
C = M / id^2,
where M = mass, i = form factor, and d = diameter of the bullet.  In easier to understand terms, Ballistic Coefficient is a relative term applied to bullets illustrating velocity loss due to friction for a given bullet specification compared
