reply to this classmates discussion post ransitional Ballistics isn't studied enough, to lump it with external Ballistics would make it more difficult to understand what's truly going on. We would end up with an umbrella study not truly showing what we need to know. When a bullet is fired from firearm, it reaches the muzzle and can oftentimes at hundreds of atmospheric pressures. Without the study of Transitional Ballistics we wouldn't know these things. With the introduction of polymer Tipton VLD bullets. We have increased the ballistic coefficient by streamlining the shape, allowing for lower drag and better aerodynamics. These new rounds are capable of taking what was a 300 yard shot with older lower ballistic coefficient ammo and create increasing them to 400 to 500 yards. On top of longer distance shots we also have more reliable feeding. Improvements in materials, bullet expansion, and propellants have greatly change the was we view environmental effects on rounds fired. From cleaner burning, more efficient propellants allowing longer faster shot to the Monumental changes in bullet shape and weight. At the end of the day, it all comes back to the study of transitional Ballistics and without that we wouldn't have any of the information available to us
