In this first video on internal ballistics Rex introduces the topic by walking through the outline of the series. Understanding Internal Ballistics is fundamental to the successful deployment of your long range rifle system. There are many interrelated factors that can affect the way your rifle vibrates which can dramatically affect the axis of your bore changing your point of impact from round to round. In order to develop the skills necessary to deal with these unseen variations, one has to study how different conditions inside the rifle affect the motion of the projectile.
For those of you who want to keep this all organized, here is the basic outline of what this portion of the series will cover:
