Today’s episode was originally, Episode-382- All About Ballistics and Ammunition Components and was originally published on February 19, 2010.
I get a very large number of questions about ballistics terminology, cartridge specific questions and a lot of questions from very new or even aspiring first time gun owners. Well today I am going to help you with the “ballistics code” so to speak. Often you can hear a conversation between two experienced rifleman and it sounds almost like a foreign language. So today I will tell not just what many of these terms mean but why they matter and even why some don’t matter that much at all.
Tune in Today as we Discuss…
- What is bullet vs. what is a cartridge vs. what is a case
- What is trajectory
- What is ballistic coefficient
- Why more velocity or a lighter bullet is often not the answer
- What is sectional density
- What is expansion, why does it matter
- What is a magnum round vs. a non magnum round
- What do all the numbers mean
- Why is a 38 Special a “special”
- How can a 38 Special be the same caliber as a .357 magnum
- What is necking up or necking down
- How are most “new” rifle rounds created
- How can a short 308 be almost as powerful as a 30-06
