Most of them do. As for bullets designed for maximum penetration on impact, hollow point and soft point cartridges are probably what you're referring to. Hollow points are more common for defensive rounds, and soft points are common hunting rounds.
wrong, a hollow point does not explode it expands on impact
A bullet that expands upon impact is commonly referred to as a "hollow point" bullet. The cavity at the tip allows it to expand and create a larger wound channel, which can enhance stopping power and minimize the risk of over-penetration. This design is often used in self-defense and law enforcement ammunition.
I'm guessing you mean a hollow point bullet, which do general expand when they hit something.
Yes, any bullet can kill you. The amount of damage a bullet does depends on several factors, basically: where it hits you, how hard it hits you, and how big the bullet is (or how much it expands).
no
Yes, a bullet can be reflected by a hard surface such as metal or concrete, depending on the angle of impact and the surface's hardness. However, the bullet's velocity might decrease after reflection due to energy loss upon impact.
Yes, any material will reduce the impact of a paintball.
Yes, a bullet can potentially knock someone over with the force of impact. However, there are many variables that can influence the effect of a bullet, such as the caliber of the bullet, the distance it is fired from, and where it strikes the body.
What caliber? What bullet weight? How far away from the muzzle? What is the ambient temperature? How close to the equator? What continent? What angle is the bullet going to impact at?
It depends on several factors. First, do you mean .45 ACP? .45mm bullet is not a handgun bullet. If you do mean that, here is a basic answer. It depends on several factors: the particular cartridge specifications, where/what it hits, whether it hits a vital organ, whether it expands.
A bullet is propelled by the controlled explosion of gunpowder in the cartridge. When the gun's firing pin strikes the primer, it ignites the gunpowder, which rapidly expands to create gas pressure that propels the bullet down the barrel and out of the gun.
It makes the bullet flatten on impact, doing more damage to the poor target animal.
