Episode-51- TSP Rewind – All About Ballistics and Ammunition Components

rewindToday is an episode of TSP Rewind, commercial free versions of past podcast episodes.

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

  1. Great rewind, Jack. I like the gun and cartridge shows; I just finished an AR build in 6.5 Grendel and it was cool to learn stuff about the 6.5mm bullet I had forgotten. Also it’s good to hear the “Another Day, Another Dollar” song again. Good luck on your hunting trip.

  2. This episode is just ONE example why I pay 18cents a day to listen!

  3. I always have a difficult time choosing which rifle to take deer hunting. The old 30 aught 6 or one of it’s offspring. It’s a good problem to have I suppose.
