Higher pressures require a bigger gun with more recoil that is slower to load and generates more heat that produces more wear on the metal. It is difficult in practice to measure the forces within a gun barrel, but the one easily measured parameter is the velocity with which the bullet exits the barrel (muzzle velocity) and this measurement will be used in examples below. (Bruner et al, 2011 ...

Brass Fetcher Ballistic Testing

It has been shown that the 'same' bullet, impacting ballistic gelatin that is only a few degrees warmer or colder than the ideal of 39°F, can show significant variations in the measured penetration depth. Bullet expansion remains an independent factor of gelatin temperature as the density (and thus stagnation pressure) of the gelatin fluid does not change in a measureable way with ...

Ballistic gelatin has served as a simulant material since the US Army began testing it in the early 1950s. After the Miami Shootout of 1986, the FBI sought to establish a ranking system for the terminal ballistics of handgun ammunition with which law-enforcement planners could select ammunition that was most likely to be effective when shot from an officers handgun.
