Does a .45 calibre bullet break the speed of sound?

Answer 1

+ The 45 caliber is a rather slow round as far as foot pounds of muzzel velocity. 830 feet (253 meters) per second, So the answer would be no.

Answer 2

The .45 can simply fire a larger bullet at a high muzzle velocity and achieve good penetration. You could kill a violent intruder in your house at night with a bow or a spear or even a pellet gun- but when you push 230 grains into them and repeatedly, if needed, your likelihood of saving your wife and daughter from being raped and murdered is a lot better. If you want to be technical, there are three highly mass produced automatic pistol calibers larger than the .45 available, and numerous specialty calibers that are larger, not to mention rimmed cartridges. If I have no other choice than to squeeze the trigger on a hostile bad guy, I want to be sure that I can neutralize the threat as efficiently as possible. The 45 is definitely a defense round. The bad guys who commit acts of heinous gun violence almost always choose the smaller calibers of which so many more bullets can be put into the standard magazine.

Answer 4

Where in the h*ll are people getting their answers from?

45 Caliber describes the size of a bullet. Whether or not the bullet breaks the speed of sound or not depends on the force exerted on it.

If you fire a 45 caliber bullet out of a 458 Winchester Magnum rifle, it will be traveling in the neighborhood of 2090 fps, much more than the speed of sound (roughly 1100 fps). Even the slow 45-70 Govt. cartridge will launch a 405 grain 45 cal. bullet at 1330 fps.

If you want to talk handguns. A 454 Casull will shoot a 45 cal. bullet at about 1800 fps at the muzzle. Other handgun rounds like the 45 ACP leave the muzzle at 850 fps, less than the speed of sound. The 45 Colt launches a bullet at 860 fps (again below the speed of sound).

In the end, it all depends what you are firing the 45 cal. bullet out of.

So does it break the speed of sound? Maybe..

Answer 5

Most .45ACP loads have heavy bullets at moderate velocity. The military load is a 230 grain bullet at 800-855 ft/sec, while sound travels at 1087 ft/sec at sea level. The .45 Colt revolver load for western models may have 255 grains at 900-950 ft/sec. If you want a supersonic .45, you must move up to Magnums, e.g. Cassull (the original), Linebaugh or a couple of newer ones. These guns kick a bit. Most 9mm Luger, .357 Magnum, .41 Magnum and .44 Magnum loads are supersonic, but standard .45's aren't.

Answer 6

Depends. Their are a lot of .45 rounds out there. A .45 ACP will not. A .45 colt will not in most factory loads. A .454 Casull will. A 45/70 (and the varous 45/90, 45/110) will, A 458 Mag. will. Alot depends on if it is a hunting round or not.

Answer 7

WHICH .45 caliber bullet? I presume you're asking about the .45ACP (Automatic Colt Pistol), which is way below the speed of sound but a lot better man-stopper with a 230 grain full metal jacketed bullet than the 9mm Parabellum, which is also a century-old cartridge and one that uses a bullet of half the weight.

The U.S. military knew this fact 100 years ago, and is FINALLY revisiting the issue and bringing the .45's out of storage.

Answer 8

As long as it travels fast enough to deliver a message to the next the shooter in a mass shooting rampage , is all that matters .Conceal carry persons can do that job .

Answer 9

no,it travels below the speed of sound.Which accounts for it's loud roar.It is classified as having,"low velocity".This gives it's round the ability to stop,and repel any advancing force.During the fighting in the Philippines,it was developed to stop native warriors, who would continue to attack even after being shot with the typical,"ball round".

Answer 10

YES & NO
Yes, it can do so if it has a high enough velocity.
No, it depends on ammo loading & barrel length. So 100% of time one can not say it does. Different ammo will give different results.
