"stopping power" is sort of hard to define, because what it means exactly depends on who you ask. However, a possible answer to the question is, the .40 SW has (approximately) between 400 and 500 ft-lbs of muzzle energy and creates a hole at least .40 of an inch in diamater (and larger, if it expands).
The main difference between a 9mm and a .45 caliber bullet is the diameter. A 9mm bullet has a diameter of 9 millimeters, while a .45 caliber bullet has a diameter of .45 inches. The .45 caliber bullet is larger and generally heavier than the 9mm bullet, resulting in differences in recoil, speed, and stopping power.
A .40 caliber bullet typically travels farther than a 9mm bullet due to its higher muzzle velocity and larger size. The .40 caliber bullet has more energy and better ballistic performance, allowing it to maintain its velocity over longer distances compared to a 9mm bullet.
Stopping a kick abruptly can lead to loss of balance, decreased power, and increased risk of injury. Following through with a kick allows for maximum power generation, better accuracy, and a smooth transition into the next movement.
Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts
At 20 mph, the average thinking distance is around 20 feet, while the braking distance is approximately 20 feet as well. Therefore, the overall stopping distance for a vehicle traveling at 20 mph would be around 40 feet.
This is mainly personal preference. The 9mm rounds will result in a lighter, cheaper round to shoot, but offers significantly less stopping power then a .40 caliber bullet. If it was going to be your primary concealed carry firearm, I'd go with the .40 because of the extra stopping power. Once again though, this is all personal preference.
357 has more stopping power. It also has quite a bit more recoil, though.
17 Remington.
The stopping power of a caliber depends on various factors, including bullet weight, velocity, and design. Generally, the .45 caliber (typically a .45 ACP) is known for delivering a larger and heavier bullet, which can result in greater stopping power due to its mass and diameter. The .44 caliber, often referring to the .44 Magnum, can achieve higher velocities and energy levels, making it formidable in terms of stopping power as well. Ultimately, the effectiveness of either caliber will vary based on the specific load and the context in which it is used.
The .40 caliber typically has greater knockdown power than the 9mm due to its larger bullet diameter and heavier weight, resulting in more energy transfer upon impact. While the 9mm is effective and has less recoil, allowing for faster follow-up shots, the .40 caliber is often preferred for its stopping power in self-defense situations. However, the effectiveness of either caliber can also depend on factors like bullet design and shot placement.
Depends- WHICH 38 caliber- and which cartridge. The .38 S&W is a relatively weak cartridge, but the .38 Special has been loaded to much higher energies. SOME .38 specials have more stopping power than SOME .380s. and vice versa. The .38 Super Auto has MUCH more power than the .380.
Size and relative power. A .40 caliber bullet is .40 of an inch and the entire cartridge is 28.8 millimeters long. A .50 caliber (handgun) bullet is .50 of an inch and the entire cartridge is 40.99 millimeters long. The .50 caliber has more powder, more velocity, and more muzzle energy.
The caliber for one.
No
the 40 cal is a little bigger then the 357
40
Which is better- Spaghetti or pizza? The .40 cal has more energy, and appears to be a higher "stopping power" round than the 9mm Parabellum. The 9mm has less recoil, and the ammunition is (generally) less expensive. You will find folks that can argue BOTH sides of this questions. EDIT* The .40 is generally preferred in combat situtations as it is significantly more powerful and is not too much bigger.
