What are the factors to consider in a bullet that affects its impact or damage to the target?
Exterior ballistics concerns a number of different factors. Among them are: velocity, bullet drop, trajectory, mid-range trajectory, maximum ordinate, line of departure, wind deflection, shot angle and maximum point-blank range.
Are bullets hot when fired?
According to research by FLIR (manufacturer of thermal imagers) the surface temperature of a fired bullet is up to 500°F. Most of that is due to friction with the barrel. The upper limit on how hot a bullet can get on impacting an object is a function of the bullet’s mass and its kinetic energy on impact.
Which is more powerful a 357 magnum or a 9mm?
357 is more powerful than 45 ACP which is more powerful than a 9mm. Up to 125 grain bullets the 9mm can pretty much match . 357 Magnum velocities if both guns are the same barrel length.

What is the one shot stop rate of an AR bullet?
Studies have shown approximate one-shot stop rates at around 60 percent – near double that of handguns. Mathematically, a standard 55-grain AR bullet delivers approximately 1,200 foot-pounds of energy. Hold that thought for a hot second. Make no mistake, handguns can stop attacks too.
