The magic that happens in a firearm’s chamber is remarkable.  When you consider what can go wrong, it is also terrifying.  Using the correct ammunition for your gun is so important that it is on every “ten commandments” of gun safety list.  To use the correct ammunition, you need to understand what “correct” is.

This series of articles explores every nook and cranny of the chamber-versus-cartridge discussion for the two chamber-cartridge pairs of concern: 5.56 NATO/.223 Rem. and 7.62 NATO/.308 Win.

College of Ballistics

Click-Bang-Ding.  The journey from the chamber to target is a fast one.  You have probably never actually seen what happens between the click and the ding.  Everything that happens to a bullet from the moment you pull the trigger to the moment the bullet stops moving can be summed up in one word: ballistics.

This series of articles is so substantial, that it is it’s own college within PBU.  We will do our best to explain everything you need to know about the journey of a bullet.
