In cases with a trajectory through the cranial fossae positive results were obtained up to 9 mm (pistol) or even . 45 (revolver). Fractures in anterior parts of the base of the skull were a rather frequent finding (82% of the cases) and could also be observed in victims shot by low energy guns.
You have to hit it when they put their nose down to ... Many pistols, including the 9mm, . 357 Magnum and . 45 ACP, have the capability of penetrating a human skull and causing serious injury or death.
At close range any round from a 9mm will penetrate and is almost certain to cause fatal damage. at point blank range, any gun gun will penetrate the skull. there may be individual cases where a combination of skull thickness, angle, and distance may add up to non penetration.
A 9mm will just make a bigger hole. Bruv a 22lr in the head can kill you, a 9mm is significantly larger, it just depends on where in the head the person shoots you and the range at which they do so. It also depends on how close to a hospital you are. Chances are very high that 9mm to the head will kill you.
A bullet traveling at only 150 feet per second (46 m/s) to 170 feet per second (52 m/s) can easily penetrate human skin and at 200 feet per second (60 m/s), that same bullet can penetrate the skull. Even a bullet that does not penetrate the skull may still result in an intracranial injury.
22 LR has ample energy to penetrate the human skull and has had military application in WWII and Vietnam primarily in covert assassination by close range PBI (17).
Yes. This is one of the huge issues with the “everybody has a gun to stop a bad guy with a gun in a crowd”: It is entirely possible that a bullet can penetrate a person, pass through and injure or kill someone behind that person.
For example, a run-of-the-mill 9mm “ball” load of Federal American Eagle 124 grain FMJ (full metal jacket) at 100 yards has a velocity of around 960 fps, for an energy of at least 250 ft/lbs, which is certainly capable of inflicting a lethal wound.
The 9mm round has about a 34% chance of stopping an aggressor with just one shot.
A 9mm is smaller and lighter compared to the . 45 ACP. Therefore, it moves more quickly and has more penetration into the target. In addition to that, it also has higher velocity, giving more stopping power to halt the bullet.
A gunshot next to your unprotected ear will expose you to up to 190 decibels (dB), beyond the level at which permanent hearing loss is possible. But regular exposure to gun blasts of 90 dB are still enough to inflict hearing loss. Wondering if even shooting a 9mm pistol without ear protection is ok? Think again.
These FMJ bullets will NOT expand in tissue and have rather modest velocity. A hit on the human body will generally poke a 9mm-size hole through whatever it encounters. The damage depends on where it hits. A hole through your brain, heart, or spinal cord is pretty serious.

Likelihood of a Cartridge Going Off
When this happens, the bullet will land in a way that prevents the impact from being sufficiently forceful to cause the bullet to fire. Significant impact to the primer would be needed to cause it to discharge. This is extremely unlikely to happen from it simply being dropped.
14 inches of fat only slows bullet
The 14 inches of gelatine only managed to halve the speed of the ball bearing, but not stop it. The Naked Scientists hypothesised that it would take at least twice as much fat to stop a bullet. “That is 72 centimetres [28.3 inches] of fat and is somewhat unfeasible,” they concluded.
9mm or 22LR For Self-Defense
While the 22lr is accurate and easy to shoot it does fail to penetrate adequately. The 9mm, on the other hand, was specifically designed as a combat cartridge. As the standard round for the US Military and NATO, it is much larger and powerful than the 22lr.
There is a significant difference in terms of kinetic energy between the 10mm Auto and 9mm Luger, with the 10mm delivering almost double the ft-lbs of energy at the muzzle.
The Federal HST +P 124 gr round is the top performing 9mm self-defense ammo. It has the highest muzzle velocity, at 1172 ft/s. It also features the highest energy at 378 ft/lbs of energy. These factors alone make it your best option in hollow point ammunition.
Brick can stop sustained rifle and pistol fire for several minutes, but will eventually fall apart. With the majority of modern homes and office construction, brick walls are durable enough to bear the brunt of most handgun calibers like 9mm, . 380, .
A 9 mm bullet can travel even farther because it's smaller. "A 9 mm can travel 2.5 to 3 miles, sometimes a little further depending on the shape of the bullet," he said.
Those 9mm defenders will often counter by pointing out that 9mm rounds generally penetrate deeper than . 45 ACP rounds. As a general rule, a 9mm's faster velocity and smaller diameter will make it more likely than the . 45 to reach an animal's vitals.
AGs are known as low-velocity arms; however, they have the potential to cause brain injury, and brain penetration may occur especially in the relatively less resistant and thin sites of the skull such as the orbit and temporal and occipital bones.
The . 22 LR has ample energy to penetrate the human skull and has had military application in WWII and Vietnam primarily in covert assassination by close range PBI (17).
The .22 LR is effective to 150 yd (140 m), though practical ranges tend to be less. After 150 yd, the ballistics of the round are such that it will be difficult to compensate for the large "drop".
