The importance of the proper use of a chronograph is not one that I would ever understate. One of the biggest influences on the performance of a given cartridge of any caliber is the speed of the projectile as it leaves the muzzle.

Setting up the chronograph properly and what the different results mean are a little less known to the average shooter. So this post will explore what a chronograph is, how to set it up, and how to interpret the information the chronograph gives us when using one!
