For anyone who knows anything around Superheroes, the expression for Superman was constantly “faster 보다 a speeding bullet”. It’s an adage draft to give the impression of an excellent speed.But that begs a really obvious question, specifically how rapid is a bullet?Bullets come in different calibers (diameter that the bullet) and also this roughly is the determining factor in cartridge speed. A 22lr caliber bullet will exit the barrel between 1200 and also 1750 feet per second (820 to 1200 miles every hour). The larger .50 caliber round will certainly be between 2800 come 3150 fps (1900 come 2100 mph). A typical 9mm handgun would be approximately 1200 fps (820 mph).

That’s fairly a variety but it seems the very big calibers for long range shooting have a cartridge speed about twice that of the tiny caliber rounds.There are a lot of components though, and there is no straightforward answer come the question, so let’s walk v it.

What perform We mean By bullet Speed?

Speed in the real people has numerous different connotations and is standardization in numerous different ways.We measure continent drift a lot in different ways than we measure train speed.In the world of firearms, that can acquire pretty facility as over there are countless different calibers, rifle manufacturers, ammunition manufacturers, barrel lengths, and weights.Additionally, the variety is varied, the bullet moves over a trajectory and also the timeframe is quick.To somewhat standardize the procedure the guns industry will certainly quote a bullet weight, because that a offered caliber and also the speed measured is that as it exits the barrel, in essence, once the propellant stops exhilaration upon the round.The speed at i beg your pardon a cartridge is moving the minute it leaves the barrel is recognized as the muzzle velocity.It is usually measured in feet per second (fps or ft/s), meters per 2nd (m/s), and also occasionally you will check out it quoted in miles per hour (mph).Thus you can see a 125 grain 9mm round quoted as having actually a muzzle velocity the 1225 fps.

Bullet rate By Caliber

As the speed of a bullet is quoted for a offered caliber (and cartridge), it is beneficial to check out what kind of rounds do with respect to muzzle velocities.What ns did to be go v each caliber and find the lowest and also highest muzzle velocities because that each caliber.The table below is tabulated by raising cartridge size, and usually a farming caliber. For each caliber and also an typical muzzle velocity is quoted.RoundCaliberMuzzle velocity.22LR0.223 in (5.7 mm)1,500 ft/s (1022 mph)5.56/2230.224 in (5.7 mm)3,160 ft/s (2155 mph).380 ACP0.355 in (9.0 mm)1,125 ft/s (767 mph)9mm0.355 in (9.0 mm)1,200 ft/s (820 mph).38 SPL0.357 in (9.1 mm)1,100 ft/s (750 mph).357 Mag0.357 in (9.1 mm)1,500 ft/s (1022 mph).40 S&W0.400 in (10.2 mm)1,200 ft/s (820 mph)10mm0.400 in (10.17 mm)1,300 ft/s (885 mph).45 ACP0.452 in (11.5 mm)1,100 ft/s (750 mph).308 Winchester0.308 in (7.8 mm)2,650 ft/s (1800 mph).30-06 Springfield0.308 in (7.8 mm)2,850 ft/s (1940 mph).338 Lapua Magnum0.338 in (8.58 mm)3,100 ft/s (2115 mph).50 BMG0.510 in (13.0 mm)3,000 ft/s (2050 mph)
Firstly, this was simply a table placed together to uncover if over there are any kind of useful information that can be determined.The range of speed obtainable by typically used rounds varieties from around 800 mph come 2100mph.Something amazing to suggest out is the .22LR and also .223 Remington have the very same bullet caliber, but vastly various bullet speeds. This is as a an outcome of the cartridge, i beg your pardon is design for armed forces purposes.Predictably though, the rifle calibers designed because that long range competitive shooting and also game hunting, create the greatest velocities.

How rapid Do Bullets take trip After 100 Yards?

The second the bullet pipeline the barrel it starts to sluggish down.Without the pressure of the propellant no much longer acting on the round, and also air resistance taking result the ring starts the long procedure of slowing down.I plugged some common rounds right into a ballistics calculator and also tabulated castle below.CaliberMuzzle velocityMuzzle velocity – 100 yds.22LR1469 fps1128 fps9mm1120 fps960 fps.30-06 Springfield2800 fps2597 fps.308 Winchester2820 fps2598 fps.338 Lapua Magnum2800 fps2681 fps
So, relying on usage, a round has actually lost 8 to 25% the its early stage muzzle velocity after ~ 100 yards.

What Factors influence Bullet Speed

While there are lots of rather subjective components that impact bullet speed like inclination the aim, temperature and also twist rate, there space a couple of factors the make a huge difference.These are;Bullet grain – This is basically the load of the bullet. From and also given caliber the cartridge can variety by quite a weight. A heavier bullet is harder to accelerate than a lighter one, so various other things being equal a lighter cartridge will departure with a greater muzzle velocity.Barrel length – The much longer the propellant acts upon the bullet the much longer the bullet is accelerating/ The much longer the barrel the much longer this impact acts ~ above the bullet. For this reason a much longer barrel will rise muzzle velocity.Cartridge – This is the lot and type of propellant behind the bullet. A 22LR cartridge exits at approximately 1500 fps however the similar sized .223 Remington has a enlarge cartridge behind it, so exits at over 3000 fps.So a lighter bullet, in a longer barrel through a large cartridge of effective propellant will create the greatest muzzle velocity and thus rate of the bullet.

Final Thoughts

Bullet speed can be assumed of together an interesting yet ultimately trivial exercise.. Obtain struck by a bullet and also you and also whatever it access time takes a lethal wound.The truth is that matters, particularly at variety as it’s a key component in wound lethality i beg your pardon is important when a cartridge is provided in the self defense role. Especially against armor.The FBI has actually a traditional test the caliber, and also a ring must have actually a certain penetration depth to be thought optimal for a defense role. If a ring penetrates between 12 come 18 customs of ballistics gel then it is thought about optimal. Less, and also it’s not good enough, and more risks the bullet passing v a target and possibly injuring an chaste bystander.Additionally, that is thought that a bullet must be travel at least 250 fps to have a 50% opportunity of penetrating the skin.A slower bullet is also much more blown turn off course by the wind so it’s taken right into account by long variety snipers.Bullet rate is an interesting and deep topic, but for most, it’s an interesting piece of info rather than anything practical. As many rounds are lethal past where they deserve to be accurately aimed, is over there anything in reality wrong with that.
