There are many different variations of .22LR rounds. Some have higher or lower grain bullets, some even have different shapes, and different brands could be higher or lower quality. These factors, along with the distance from the geletin, affect the bullets penetration ability. The length of the barrel of the firearm can also have an affect because shorter barrels don't allow for as high an exit velocity for the projectile.
It is possible.
It depends - logically - on the caliber of the bullet, and the thickness of the pine. A deer rifle bullet will penetrate a 2x4 with no difficulty, and may or may not penetrate a 4x4. A .22 will penetrate neither, a .50 machine gun bullet will penetrate an 8x8. Loosely speaking, I would not consider pine to be a bulletproof material.
EASILY. We;ve done them with .22 Magnums before.
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.
Generally they don't. Lighter bullets generally have a worse ballistic coefficient as compared to heavier bullets of the same caliber.
Bullet ballistics refers to the behavior of a bullet in flight, including factors such as velocity, trajectory, and accuracy. It involves studying the impact of various variables like distance, wind speed, and bullet design on the bullet's performance upon firing. Understanding bullet ballistics is essential for precision shooting and hunting.
Depending on the distance, yes. At close range, definitely yes.
It's a .30 caliber bullet.
A 22 caliber bullet is 22/100 inches in diameter. A 7.62 mm bullet is 30 caliber or 30/100 inches in diameter there is no such thing as a 7.62 caliber bullet
Under most circumstances, a .22 can easily penetrate human skin. There have been numerous fatal shootings with .22 cal firearms- and even a .22 pellet gun can penetrate skin.
No. Not even close.
caliber 38 is a caliber 38. bullet dia. is .357 caliber deals with the dia. or measurement around the bullet head, not the bullet case.
