The higher the number, the less drag the projectile will experience. Find load data for your cartridge. Well, for 50 BMG, you're looking at $11-$16/round for military surplus ammo. [citation needed], In June 2017, a McMillan Tac-50 was used by a sniper with Canada's Joint Task Force 2 to kill an Islamic State insurgent in Iraq, setting the new world record for the longest confirmed kill shot in military history at 3,540 meters (3,870yd; 2.20mi). You might be asking yourself if the velocities shown here are enough for proper expansion of such a large bullet such as the .50cal. We dont have a single set of data we can look at to determine stopping power. A wide variety of ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower quality rounds. In this way, the user can know how much recoil the 50 BMG round has due to impact. This is because the bullet is very large, so the wound it makes is also large and deep, but still curable. Your email address will not be published. Looking at just the basic physics, a .50 bmg has a muzzle velocity of about 420 meters per second (1480 feet per second). Your email address will not be published. Maybe even more so when looking at these two rounds. If you have any feedback or question about my articles, please submit it here, it's always appreciated! Lets take it a step further and take a look at the rounds we have selected for comparison. This limitation was entirely tactical in nature and was intended to hide the vulnerable M40 and its crew from the enemy until the main anti-tank gun was ready for firing; however, Parks concludes that some U.S. troops assumed the existence of a legal limitation on the use of .50-caliber projectiles more generally. To be able to push such large bullets to speeds that make them useful is going to take a good deal of powder and both have the casings to hold it. I agree with Michael. Thank you. The 50 caliber is a 5.5-inch length seated bullet. Before we get into our comparisons, there is one more note that we would like to make. Properties. A common way of comparing ammo power is checking their muzzle energies. Thus, to begin zeroing on an optically centered scope, you have to come down 30 minutes at the start. These are factory loads that are available for purchase. As the 50 BMG bullet has a high ballistic coefficient, it is used for powerful sniper rifles. Now, in this section, we are not looking technically at the actual felt recoil but instead at the recoil energy(ft.lb) that is generated when firing these rounds. The standard projectile on which all Hornady Bullets were compared was the G1 Model, based on work begun in France and refined at the U. S. Army Ballistic Research Laboratories, Aberdeen Proving Ground, Maryland. Coming up on wounded animals, especially if they are predators, can be dangerous and being able to drop them cleanly takes this risk away. A bullet's BC is typically less than 1 and recorded to the thousandth decimal place (with notable exceptions; the 50 BMG's BC exceeds 1.000). Both are going to penetrate just about any hide or armor that is out there, its what they were designed to do, and we have seen from the velocities that they are going to speed and power behind them to get the job done. For hunters, stopping power is a critical factor in choosing a certain cartridge. In ballistics, the ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. . The .50 BMG is an impressive long-range cartridge, especially when paired with a high-quality bolt-action or semiautomatic rifle and a good optic. It is a great investment if you want to get into long range shooting and will be especially useful if you handload. For the 50BMG, we are not going to give a specific round. The majority of its use in these circles is through extreme distance shooting though there are small circles that utilize it for hunting purposes, mostly for large or dangerous game at extreme distances. Can a 50 cal rip your arm off? Usually, these can leave a severe wound. If we take a closer look at the averages of the round, we see that the 50BMG rounds carry from 200fps (Muzzle-700yds) to 300fps (800-1,000yds) more than the 338LM rounds, which is quite remarkable given how much heavier the 50BMG rounds. The less a bullet drops during its flight, the easier it is to make adjustments for longer distance shots. Various ammunition is also available to allow firing with lower quality bullets. While this is important to understand, its equally important to remember that the SD, while a good means for comparing two cartridges, only tells part of the story when it comes to penetration. Most .50 BMG rounds are not designed for much expansion. This cartridge can easily take shots at 1,000+ yards just as the 50BMG, but there might be more dramatic adjustments needed to be made for these shots when compared to the 50 BMG. Even after the differences between 50 Cal vs 50 BMG, we see that they are quite similar in various features. So, it is evident that the bullet is dangerous and needs care while in use. Re: 50 BMG goes subsonic at 1500 Yards? These are excellent speeds for long range shooting, especially when shot from a rifle with the proper twist rate to stabilize them in flight. The round is a scaled-up version of the .30-06 Springfield but uses a case wall with a long taper to facilitate feeding and extraction in various weapons. While the .50 BMG round is able to deliver accurate shot placement (if match grade ammunition is used) at ranges over 1,000-yard (910m), smaller caliber rifles produce better scores and tighter groups in 1,000-yard (910m) competitions. So there is a fine line a lot of hunters try to walk when it comes to penetration. If we have two bullets with the same weight, but different diameters, the smaller diameter localizes the force to a smaller area and gives you deeper penetration. Brands like Smith & Wesson, Magnum Desert Eagle, Magnum Research, Guncrafter Industries, Ruger Super, Safety Harbour, etc create the best pistols for 50 BMG. Huge bullets with enough powder to send them downrange at supersonic speeds are going to produce enough kick to knock you down. This is by no means a comprehensive list, but it does include some of the more popular rounds for each cartridge. These include heavy stopping power that can be carried over incredible ranges. Barnes Solid Bore Rider Bullets 50 BMG (510 Diameter) 750 Grain Spitzer Boat Tail Box of 20 Developed to reduce pressures and allow higher velocities, this bullet is constructed of a homogenous metal throughout with no lead core or jacket to separate on impact. The SD comes from the diameter of the bullet and the weight of the bullet. This data was taken from the standards used by the ballistic calculator for the .338 LM and the .50 BMG rounds. The following ins a 500 yd 270 Win ballistic trajectory and drop chart that follows a 130gr Winchester Silvertip with a ballistic coeddicient of .337 from the time it exits the muzzle until it hits the 500 yard mark. However, Los Angeles banned this bullet round. While Glock is a master of simplicity and reliability, Walther has gone for a more elaborate design. Answers to Top Questions", https://en.wikipedia.org/w/index.php?title=.50_BMG&oldid=1139367557, Winchester Repeating Arms Co. and Frankford Arsenal, Serbu Firearms BFG-50a (magazine fed semi-automatic), Serbu Firearms RN-50 (single-shot modified break-action), This page was last edited on 14 February 2023, at 19:38. Try these all-copper . American interest in an armor-piercing cartridge was influenced by the marginal French 11 mm design, prompting U.S. Army Ordnance officers to consult Browning. They are widely used by civilians as well as military forces. The gathered data regarding the projectile deceleration can be derived and expressed in several ways, such as ballistic coefficients (BC) or drag coefficients (C d). There is no doubt that the cartridge has the power and the trajectory to take on this challenge, but there is always the ethical question of taking shots at animals from these ranges. It is a bit much for medium size game at short ranges, but it would give you a huge advantage at long range if you believe that hunting ethical. These bullets are magnetic. We think a flat trajectory also gives you a little more room for mistakes when it comes to judging distance quickly, as is sometimes the case when hunting. Its range and accuracy, however, are superior to light machine guns when fixed on tripods, and it has not been replaced as the standard caliber for Western vehicle-mounted machine guns (Soviet and CIS armored vehicles mount 12.7108mm NSVs, which have similar dimensions to .50 BMGs). PMC X-Tac Match combines all the performance of world class ballistics with a price point that is friendly for your wallet. This Federal American Eagle 50 BMG ammunition is perfect for target shooting, competition shooting, long-range hunting, and long-range shooting.This American Eagle ammunition was produced by Lake City Arsenal to NATO specifications. And like we said, if you need a large cartridge like both of these are, you probably already knew you were going to be dealing with recoil. Stringent quality control ensures proper bullet seating, consistent charges and pressures, optimal velocity, consistent overall length and repeatable accuracy. Please let me know how it can be improved upon. The increased interest in the .338 LM in civilian circuits has resulted in more round options though still limited compared to other competition and hunting rounds. There are various types of weapons used for 50 caliber bullets. Bullet velocity is a very important ingredient of successful long-range shooting. Some of them can also be semi auto-loading guns. Since a .50 caliber bullet is manufactured with a solid metal surface and core, it is very powerful. Subject to political controversy due to the great power of the cartridge (it is the most powerful commonly available cartridge not considered a destructive device under the National Firearms Act), it remains popular among long-range shooters for its accuracy and external ballistics. Still, with the categories we have examined so far, we can infer some information in a roundabout way when it comes to the potential accuracy between the 338 Lapua Mag versus 50 BMG. And this is case when comparing most cartridges. Subsequently, Frankford Arsenal took over from Winchester, producing the historic .50 BMG or 12.7x99 mm cartridge. By doing this, perhaps we can tease apart in which situations one cartridge might be better suited over the other. When comparing the 9mm handguns available, two models that always top the discussion are the Walther PPQ and the Glock 19. It is strong enough to hold a large volume of pressure. 338 LM Federal MatchKing BTHP Gold Medal 250gr, 338 LM Nosler Trophy Grade AccuBond 300gr. Shots traveling 1,000 yards are much more prone to these environmental factors, and we would bet that 99% of them are very aware of the BC. Excellent quality, and great customer service from Dave Moore of Spider Firearms. The higher the value, the better the bullet can travel through the air. The common rifling twist rate for this cartridge is 1 in 15in (380mm), with eight lands and grooves. The .50 BMG Flechette rifle project was contacted out by DARPA in 1960's. The projectile consisted of a saboted depleted uranium dart weighing 11.9 gram ( 183.6 grains ). It has a ballistic coefficient of .730. Best Mossberg 500 Heat Shields [Ultimate Buying Guide], Best 9mm Ammo in 2021 [Self-Defense & Target], 6.5 Creedmoor vs .243 Win Cartridge Comparison. No extra bullets are sent. In ballistics, the ballistic coefficient ( BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. It has a diameter of .50 inches, with a casing length of 99 mm and an overall length of 138 mm. The Federal Ballistics Calculator lets you quickly determine the trajectory for any rifle or handgun load, and save data for an unlimited number of loads. We arrived at these numbers by using a 15lb firearm for the 338 LM rounds and a 30lb firearm for the 50 BMG rounds, which are common weights for rifles chambered for each cartridge. a 50 caliber bullet weapon is considered violent. [36][37] California prohibits the private purchase of a rifle capable of firing the .50 BMG through the .50 Caliber BMG Regulation Act of 2004. [3], In response to the need for new anti-aircraft weaponry during World War I, John Browning developed the .50 BMG. .50 BMG Ballistics Variables Bullet Weight: 661 grain Ballistic Coefficient: 0.62 (G1) Scope Height: 3 inches Ambient Conditions Temperature: 59 Pressure (absolute): 29.92 inHg Cross Wind (90 or Full Value): 1 mph MODEL 82A1 .50 BMG (29 BARREL) MODEL 82A1CQ .50 BMG (20 BARREL) DOWNLOADS Due to the high ballistic coefficient of the bullet, the .50 BMG's trajectory also suffers less "drift" from cross-winds than smaller and lighter calibers, making the .50 BMG a good choice for high-powered sniper rifles. Still, by comparing the recoil energies, it will translate loosely into what you feel. Even if we had all of the rounds and a couple days to generate some MOA measurements it still might differ on another day in someone elses hands. Ballistic Coefficient is essentially a measure of air drag. Heck, the BC of a bullet can change based on temperature, altitude, and pressure. But it differs from other types of 50 caliber bullet rounds. . With the .338 Lapua Magnum vs .50 BMG, recoil takes on a bit more of an important role. From over 4,000ft.lb of energy out of the muzzle to between 1,000 and 2,000ft.lb at 1,000 yards, it too has incredible range when it comes to having the energy needed for most game animals in the world. For the .338 LM, we recommend the Nosler Trophy Grade AccuBond 300gr round. The .50 BMG round can produce between 10,000 and 15,000 foot pounds (between 14 and 18 kilojoules), depending on its powder and bullet type, as well as the rifle it was fired from. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. A user can shoot easily from a distance of about two kilometers. To make it as accurate as possible, it is important that you input the most accurate information that represents shooting conditions, your firearm, and cartridge. Fillable and printable Ballistic Chart 2023. If you decide to make a go with the .338 or the 50 BMG, with some practice, youre going to have an accurate cartridge. [1]) is a .50in (12.7mm) caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Ballistics Coefficient (abbreviated "BC") is a bullet's ability to resist air friction and stay airborne. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. From the bullet seating to the optimal charges and velocities, Hornady Match ammunition is designed to live up to company founder, J.W. It has velocities that compete with the 50 BMG rounds, one of the flattest trajectories when compared to other .338 LM factory loads, and a ballistic coefficient of nearly .8. Federal Ammunition 50 BMG Ammo Details. What is ballistic coefficient (BC)? 50 Cal is generally known as the bore and the nominal bullet diameter. The purpose of this cartridge was to was to provide snipers with a long range round that had incredible terminal ballistics and could penetrate several layers of body armor at extreme distances. Muzzle 100 yds. kilojoules). On 14 April 2001, 19-year old Senior Airman Jennifer Donaldson, from the Illinois Air National Guard, made history. To make it as accurate as possible, it is important that you input the most accurate information that represents shooting conditions, your firearm, and cartridge. With such differences in cartridge specs, we can assume that the ballistic performances are going to be quite different as well. 50 Caliber has different types of rounds, while 50 BMG is a particular one. In this section, we will take a look at bullet energy and penetration for comparing the 50 BMG vs 338 Lapua Magnum. And if you need the performance of the 50BMG, you are probably already aware of what you are in for and with todays modern gear, you are perfectly capable of using this cartridge efficiently.

Caliber Multi: .50 BMG Application: Hunting . For hunting, a lot of hunters want expansion to cause a larger wound and more damage. As we mentioned above, firing these rounds often requires heavy firearms and other pieces of gear that help negate this recoil. This can be useful in comparing cartridges or loads. Teamed with Colt, he produced prototypes ready for testing and, ironically, completed them by Nov. 11, 1918the Great War's end. As you can imagine, the bigger the game, the more energy you are going to need to cause enough damage for a clean kill. The Barrett Mk. The 50 BMG is the winner of this section..50 BMG vs .50 Beowulf: Stopping Power. Unsubscribe at any time. [35], In the United States, Washington, D.C. disallows registration of .50 BMG rifles, thus rendering civilian possession unlawful. The .50 BMG was developed during World War I when looking for an effective anti-aircraft round. Sometimes, the wound may be fragile, but it may also get fatal. The rounds intended for machine guns are made into a continuous belt using metallic links. This is why it is used in heavy-duty shootings. 300 yds. Both of these cartridges have found a place in the long range shooting. If you're looking at doing match ammo, you could be paying $5/round just for the bullet, nevermind the powder, primer, brass and other components. The Ballistic Coefficient of tangential ogive jacketed bullets traveling at velocities above the speed of sound can be calculated to a reasonable degree of accuracy if careful measurements are made to determine the actual radius curve of the nose portion and the boat tail (if any) dimensions. In certain aspects and certain situations, sure, there are cartridges better suited to the task than others. To handle these rounds in the field, youre going to have to haul around a 30+lb rifle. 50 BMG ammo is a large, round sniper bullet. [14], Some civilians use .50 caliber rifles for long-range target shooting: the US-based Fifty Caliber Shooters Association holds .50 BMG shooting matches. It couldnt be more clear that the 50BMG carries exponentially more kinetic energy with it than the .338 LM rounds. Zero Range (yd) Users can easily use them for personal use. However, bullets shot from pistols are slower as the gunpowder takes longer to burn. Seriously, these are heavy duty rounds that fill a very specific niche in the shooting world. They have various models for different cartridges. What is the best scope for a .50 BMG and what is the strongest 50 BMG? But thats the case with just about every round and is one of the many reasons that a lot of us have fallen in love with the sport. The surface is dirt and water-resistant. Not match ammo. This is the best ballistic coefficient of any bullet to date. The bottom line is this. The auctioneer claims that it is only one of twelve built and the only other known example resides at the Ford Benning sniper school. [30][31] The M15-series metal "push-through" links were used in the M85 machine gun. Velocity is key for proper penetration and expansion, which is critical for hunting. This is near impossible to handle accurately unless accessory gear is used to help absorb and stabilize the rifle. [42] Maryland imposes additional regulations on the sale and transfer of .50 BMG rifles and other "regulated firearms", and limits purchases of any firearm within this class to one per month, but does not impose registration requirements or any form of categorical ban.[37]. To measure the ballistic coefficient, we need the BC projectile that is equivalent to the ballistic coefficient in a point mass trajectory of below 20 degrees. heres what ive seen on a ballistic calculator Trajectory Input Data Manufacturer: Hornady Description: A-Max Caliber: 0.510 in Weight: 750.0 gr Ballistic Coefficient: 1.050 G1 Muzzle Velocity: 2700.0 ft/s Distance to Chronograph: 10.0 ft Sight Height: 1.50 in Sight Offset: 0.00 in Ammunition is sold in 80-round cases. Spitzer. We hope that this article has highlighted these differences and provided you with a reliable source for making your own decision of which cartridge better fits your needs. In addition to the usual tables and graphs of drop, velocity, and windage, Modern Ballistics has these unique features: Sight Angle. These rounds are listed below. Important: Since there are thousands of bullet shapes the Ballistic Coefficient calculations made below are not 100% accurate, if you are shooting out past 400-500+ yards your going to need to get the exact BC from the bullet's manufacturer. These are extremely large rounds that require heavy weapons as well as other equipment to shoot accurately. The following improvements will be made: Please sign up for our newsletter so that you can be alerted the moment these new features are launched! Military Applications: Note: We have selected two different 50 BMG loads to demonstrate here. As we have done in previous sections, we are going to look at our ten selected rounds. . It has a sectional density around 0.44, a ballistic coefficient around 1.13, and it's carrying less than 15,000 ft-lbs of energy at the muzzle. 50 BMG is one of the types of 50 caliber cartridges used for 50 BMG machine guns. It comes in different types like tracer, armor-piercing, usual ball, incendiary, and sub-caliber rounds. Lake City 50 BMG Ballistic Data. Ballistic Coefficient (BC) is basically a measure of how streamlined a bullet is; that is, how well it cuts through the air. On the other hand, talk to F-class competitive shooters, and the trend is the opposite. Mathematically, it is the ratio of a bullet's sectional density to its coefficient of form. Firearm Setup. PMC X-Tac Match .50 BMG Ammunition 10 Rounds 740 Grain Solid Brass Projectile 2830fps 50XM. For this article, we are going to explain the BC in the simplest of terms. The ballistic coefficient is derived from an equation that uses several bullet and cartridge variables. The ballistic coefficient or measure of drag for the .50 BMG is 1.05 which, is higher than any other commercially available around. With that being said, we wouldnt recommend hunting the majority of game on planet Earth with a 50BMG; it seems pointless with the amount of damage it would cause to perfectly good meat. Besides military and police organizations, the .50 BMG has gained popularity in some civilian circles. In this cartridge comparison, we are going to take a look at two cartridges, the .338 Lapua and the .50 BMG, two rounds that separate the men from the boys. The .50 Browning Machine Gun (.50 BMG) was developed for the Browning .50 caliber machine gun in the late 1910s as countries began producing armored vehicles leading up to WWI. Machine guns use it as a continuous belt of rounds. Military use 50 caliber in machine guns and snipers, as well as regular shooters.
