2. Transitional ballistics - Wikipedia

   en.wikipedia.org/wiki/Transitional_ballistics

   Transitional ballistics is a complex field that involves a number of variables that are not fully understood; therefore, it is not an exact science. [6] When the bullet reaches the muzzle of the barrel, the escaping gases are still, in many cases, at hundreds of atmospheres of pressure. [3] Once the bullet exits the barrel, breaking the seal ...

3. External ballistics - Wikipedia

   en.wikipedia.org/wiki/External_ballistics

   External ballistics. This schlieren image of a bullet travelling in free-flight demonstrates the air-pressure dynamics surrounding the bullet. External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin ...

4. Colt Walker - Wikipedia

   en.wikipedia.org/wiki/Colt_Walker

   The Colt Walker, sometimes known as the Walker Colt, is a single-action revolver with a revolving cylinder holding six charges of black powder behind six bullets (typically .44 caliber lead balls). It was designed in 1846 by American firearms inventor Samuel Colt to the specifications of Captain Samuel Hamilton Walker.

5. Evans repeating rifle - Wikipedia

   en.wikipedia.org/wiki/Evans_Repeating_Rifle

   The Evans repeating rifle is often considered to be one of the oddest rifles to ever be produced in the United States. The Evans was invented by Warren R. Evans, a dentist from Thomaston, Maine. With the help of his brother George, they perfected the rifle and started the "Evans Rifle Manufacturing Company" of Mechanic Falls, Maine in 1873.

6. Ballistics - Wikipedia

   en.wikipedia.org/wiki/Ballistics

   Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially ranged weapon munitions such as bullets, unguided bombs, rockets or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.

7. .408 Cheyenne Tactical - Wikipedia

   en.wikipedia.org/wiki/.408_Cheyenne_Tactical

   The .408 Cheyenne Tactical (designated 408 Chey Tac (10.36×77mm) by the C.I.P.) [ 3 ] is a specialized rimless, bottlenecked, centerfire cartridge for military long-range sniper rifles that was developed by Dr. John D. Taylor and machinist William O. Wordman. The round was designed with a possible military need for a cartridge for anti ...

8. Springfield Model 1863 - Wikipedia

   en.wikipedia.org/wiki/Springfield_Model_1863

   The Springfield Model 1863 was a .58 caliber rifled musket manufactured by the Springfield Armory and independent contractors between 1863 and 1865. The Model 1863 was only a minor improvement over the Springfield Model 1861. As such, it is sometimes classified as just a variant of the Model 1861. The Model 1861, with all of its variants, was ...

9. Ballistic coefficient - Wikipedia

   en.wikipedia.org/wiki/Ballistic_coefficient

   In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. [ 1 ] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
