Instead of a pointed tip, the tip of the bullet is a somewhat cone shaped hollow.
The Minié ball. It was invented in 1849 by the French Army officer Claude-Etienne MInié. He designed the Minié ball, a cylindrical bullet with a conical point. An iron cup was inserted in the hollow base so that when the ball was fired, the cup was forced forward, expanding the base to fit snugly against the rifling grooves. Indeed the American Army adopted a simplified version of Minié ball. It had no iron cup in the hollow base. The gas pressure on the base was sufficient to force the bullet on the rifling grooves.
In MOST cases, muzzle loading firearms can shoot a round ball, OR a cylindrical bullet. Perhaps the best known was the "Minie ball". Named for its creator, this muzzle loaded bullet had a hollow base. On firing, the hollow base was opened by the force of the gunpowder, making the bullet sightly larger, and grip the rifling in th barrel on the way out. Google images of the Minie ball to see what one looks like.
"Less lethal" is a very subjective term, however, a hollow point bullet is generally considered to be more effective in regards to stopping an adversary than a round nosed bullet.
No. They are a lead bullet with a jacket of copper/ nickel alloy.
The hollow in the tip of the bullet allows soft tissue to enter into the bullet causing rapid expantion.The hole in the center of the bullet allows for the bullet to expand to a wider diameter upon impact. Thusfore causing greater damage to the targetA hollow point has a pit or hollowed out shape in its tip, generally intended to cause the bullet to expand upon entering a target in order to decrease penetration and disrupt more tissue as it travels through the target. They are also used to control penetration, such as in situations where over penetration could cause collateral damage (such as on an airplane). Jacketed hollow points (JHPs) or plated hollow points are covered in a coating of harder metal to increase bullet strength and to prevent fouling the barrel with lead stripped from the bullet. The term hollow-cavity bullet is used to describe a hollow point where the hollow is unusually large, sometimes dominating the volume of the bullet, and causes extreme expansion or fragmentation on impact.
Hollow Point bullets have a hollow nose or an hole in the nose of the bullet. This causes the bullet to mushroom into a larger diameter when it hits something. A regular bullet is conical or blunt nose in shape. Some can be pure lead or can be jacketed with a bronze or copper coating.
I'm guessing you mean a hollow point bullet, which do general expand when they hit something.
Jacketed hollow point.
This depends on the particular caliber, weight, velocity, and construction of the bullet and the "Threat Level" of the body armor. No vest is bullet proof -- the preferred term is body armor.Generally speaking hollow points are much lesslikely to penetrate body armor which will stop non-hollowpoints bullets of the same caliber, weight, and velocity.
wrong, a hollow point does not explode it expands on impact
17 grains - ballistic tiped or 20grain in hollow point
