The 9mm jacketed bullet load offers excellent penetration against web gear and heavy clothing, but commercial FMJ loads seem to exhibit icepick-like effect when used against motivated felons. Sadly, much violent conflict takes place inside of homes and apartments. Amongst the excitement and data recording, we failed to pay much attention to the actual chronograph. If interested perhaps we can exchange some info or thoughts. In addition to firearms-related work, Josh enjoys working with animals and researching conservation projects in his home state of Michigan.
Courtney and Courtney, The mathematics of wound ballistics, in reference to yaw of unstable projectiles, has been described. Designed and developed by IdeaBank Marketing. One of the other things one must consider is the weight of the magazines. The higher the specific gravity, the greater the damage. The term ballistics refers to the science of the travel of a projectile in flight. Peters et al, Peters and Sebourn, Experimental methods to demonstrate tissue damage have utilized materials with characteristics similar to human soft tissues and skin.
The Speer load was difficult to obtain, but then everything is at present. The results are seen below Graph 5. Barrel burn seemed complete. A Fistful of Shooting Tips Email. After all, the bullet would be too frangible if it expanded at a lower velocity than its original design. Its performance was similar to a FMJ in this caliber. Ammunition that relies on high velocities require full size barrels to reach optimal performance.
Yeah, it seems strange to see the word trajectory in a comparison of handgun rounds. There are some very familiar cartridges on the table above, but a quick look at the scores indicates which bullets were designed to function after passing through the commonly-encountered tactical barriers that are addressed by the FBI Protocol. Both the speed and the mass of the bullet influence the amount of kinetic energy that a bullet carries. From 75 out to yards we do see some trends. Such a felon bent on causing human misery and suffering must be personally impressed by the ballistics of a cartridge. Rising from the ashes of the Miami Shootout of , the FBI Ammunition testing standard started with the goal of giving law enforcement planners the information that they needed to make informed decisions about the terminal ballistics of defensive handgun ammunition. The majority of the data is available from the manufacturer, and where that was not available, we relied on ballistic calculators from trusted sources.
