As I have said in the past, it is important to know the parts of your guns or at least the major parts. I still don't know all the small pieces that make up a rifle, but I do know the basics. 

The barrel, the bore are something to understand as it can be a serious issue if you try to use the wrong caliber for what the barrel is capable of handling.

When learning about the barrel and bore you'll come across rifling so I touch on what that is exactly, but not much further as I do not know much more about it yet.
