Velocity at 100yds: 946 fps . 9mm vs 40 S&W vs 45 ACP & “Stopping Power” ... Recoil is directly related to the muzzle energy of the round being used. Muzzle energy is often used to rate the lethality of certain loads. One of the twentieth century’s best-known pistol cartridges, the old.45 Automatic Colt Pistol cartridge originally supplanted the .38 Long Colt cartridge after the Moro uprisings in the Philippines showed a need for better stopping power in the pistol cartridges issued to the US military.
One of the twentieth century’s best-known pistol cartridges, the old.45 Automatic Colt Pistol cartridge originally supplanted the .38 Long Colt cartridge after the Moro uprisings in the Philippines showed a need for better stopping power in the pistol cartridges issued to the US military. Let’s see the factors that you listed: 1. The more force it … Muzzle Velocity: 1,090 fps. They have faster muzzle velocity, muzzle energy and a faster velocity. There is plenty of criticism out there that even the 9mm is underpowered and lacks stopping power. Energy. Gun publications and avid shooters can run on endlessly about the energy of certain cartridges and even specific brands of cartridges. Of course, outside and external ballistics are not as interesting as terminal ballistics. Typical Muzzle Energy Range: 244-534 ft.lbf. They have faster muzzle velocity, muzzle energy and a faster velocity. Muzzle Energy: 348 ft/lbs.
Now, most 9x19mm rounds actually generate greater muzzle energy than the average .45 ACP. Optimal 10mm Uses. Note the size of this Federal 230-grain, .45 ACP HST +P bullet, which dropped a charging hog instantly. See: Man survives 9mm head shot – Firearm Blog. Velocity at 100yds: 946 fps . As Newton’s 3rd :Law explains, any action creates an EQUAL and opposite reaction.
On these metrics, the rounds are generall equal. Muzzle Velocity: 1,090 fps. Muzzle energy is often used to rate the lethality of certain loads. Stopping power is not the same as joules or ft/lbs. Furthermore, the muzzle energy of a .357 Magnum round averages out to 530 ft-lb, while a .45 Colt (LC Long Colt) round averages out to about 500 ft-lb. Because of the faster velocity, 10mm is going to give you better long-distance shooting. As a result, more AK-type weapons have been produced than all other assault rifles combined. "
Chuck Hawks shares important information about handgun stopping power in this handy condensed version of his popular chart.
8/29/2012. Because the formula for calculating muzzle energy requires that bullet speed (by far the largest number in the mix) be squared, the power factor is distorted in favor of a … After looking at the ballistics of both calibers, we see that the 10mm has more kick.
A more important issue for a home defense gun might be keeping the bullet from killing your next door neighbor, as he's watching TV. Looking at power factor favors bullets that are heavy, even if slow. Modern bullet technology has improved many calibers. Many gun people will even use the term interchangeably with “stopping power.” Relative Stopping Power, for example, totally disregards the effects of kinetic energy, sectional density, and bullet expansion on killing power. 9mm vs .40 vs .45: Which Chambering Has More Stopping Power? A logical argument can be made that accuracy and penetration may outweigh bullet size and muzzle velocity in certain situations. In addition, if the target is a woodchuck or a moose, that is the bottom line—terminal ballistics.
