This shows most dramatically in the case capacity where the .50 BMG can hold nearly 200 more grains of powder than the 338LM. Before we get into the meat of the article with our comparisons, we want to briefly touch on how these two cartridges look up next to each other. They are both quality handguns, but their makers have taken two very different approaches to the designs. There are various types of weapons used for 50 caliber bullets. Receive exclusive gun deals once a week and all our great reviews right in your inbox. Teamed with Colt, he produced prototypes ready for testing and, ironically, completed them by Nov. 11, 1918the Great War's end. Us has made 50 BMG the standard as the largest bullet round in terms of shell size. All of them but one .338 LM round break the .55 mark. Its because 90% of their shots are coming at 250 yards or less. 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). '"[5], The American Rifleman further explains that development was "[r]eputedly influenced by Germany's 13.2x92 mm SR (.53-cal.) The 50 BMG is another caliber with . As we mentioned earlier, the velocity has a lot of influence on other aspects of the bullets behavior such as expansion. Each cartridge is loaded with either Hornady A-MAX bullets, our high-performance boattail hollow points, or the new, radically superior ELD Match bullets. Brands like Smith & Wesson, Magnum Desert Eagle, Magnum Research, Guncrafter Industries, Ruger Super, Safety Harbour, etc create the best pistols for 50 BMG. It also has a strong recoil force as the cartridge is filled with powder. And like the 50BMG rounds, we will revisit this shortly. 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 ). 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. Still, by comparing the recoil energies, it will translate loosely into what you feel. It was developed for the M2 Browning machine gun over 110 years ago, and was based on the .30-06 Springfield cartridge. And even then, the options you have for 50BMG factory loads is extremely limited, even when compared to the .338 LM. This can be useful in comparing cartridges or loads. When a bullet is fired from the barrel, it carries kinetic energy that upon impact is transferred to the target. The two most important variables are the Initial Velocity and the Ballistic Coefficient. DARPA (Defense Advanced Research Projects Agency) contracted with Teledyne Scientific Company to develop the EXACTO program, including a .50-caliber guided bullet. It might not compete with some hand loaded cartridges, but you cant get much better when it comes to a factory load. It comes in different types like tracer, armor-piercing, usual ball, incendiary, and sub-caliber rounds. You might be asking yourself if the velocities shown here are enough for proper expansion of such a large bullet such as the .50cal. Powder is matched carefully to each specific load for optimal pressure, velocity and consistent accuracy. These include heavy stopping power that can be carried over incredible ranges. On the other hand, talk to F-class competitive shooters, and the trend is the opposite. I VLD was designed from the start to be as efficient as possible, remaining supersonic past 2,150 yards. [34], A 1999 Justice Department Office of Special Investigations briefing on .50 caliber rifle crime identified several instances of the .50 BMG being involved in criminal activities. [33], The specified maximum diameter of an unfired .50 BMG bullet is 0.510-inch (13.0mm); while this appears to be over the .50 inch (12.7mm) maximum allowed for non-sporting Title I firearms under the U.S. National Firearms Act, the barrel of a .50 BMG rifle is only .50 inch (12.7mm) across the rifling lands and slightly larger in the grooves. In regards to their BC a spitzer bullet has a high coefficient and is suitable for long-range shots, and the boattail spitzer is even superior making it one of the best bullets for long-range targets exceeding 1,000 yards. Since 50 BMG cartridges are unique, these have a limited number of sniper rifles built with adequate quality. Please let me know how it can be improved upon. Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 BMG can exceed this normal BC. Other than armed forces, civilians use this bullet round for target shooting and sports. Reply. The .50 BMG round can produce between 10,000 and 15,000 foot-pounds force (14,000 and 20,000J), depending on its powder and bullet type, as well as the weapon it is fired from. The ballistic coefficient is derived from an equation that uses several bullet and cartridge variables. By understanding these different parameters, we can not only better adjust to specific shooting conditions and be aware of our limitations, but we can also begin to tease apart certain situations each of these cartridges might be better suited. To begin, these selected rounds all have excellent BCs that most would be more than happy with. "[5], The round was put into use in the M1921 Browning machine gun. From the bullet seating to the optimal charges and velocities, Hornady Match ammunition is designed to live up to company founder, J.W. anti-tank rifle" and that then "Ordnance contracted with Winchester to design a .50-cal. We will see more drastic differences between our selected rounds, and we cannot comment on the exact variables used for this result. Your Savings: $43.50 (9%) 50 BMG M33 Ball Military Grade ammunition with a 660 Grain FMJ Bullet & Brass Case. [32] Applications requesting firearms in this caliber are assessed by the same criteria as smaller calibers; with the applicant having to prove they have a valid reason for owning such a weapon. a 50 caliber bullet weapon is considered violent. However, the strength depends on the sturdiness and power of the rifles used for this bullet. It has a large cartridge used in anti-material for longer ranges. Our .50 BMG ammunition is ready for action. The Heat Shield tip on the ELD Match bullet creates the perfect meplat and outperforms BTHP bullets. In some cases, it is used to detonate mounted guns or cannons. You make up some cartridges and we'll do some shooting. [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]. This is roughly the same as saying that the projectile in question possesses low drag, although some meaning is lost in the generalization. They are of premium build to make precise targets with less recoil. It uses a boxer primer with a central ignition point. Federal Ammunition 50 BMG Ballistic Data. If the bullet passes through cleanly, remaining relatively intact, not all of the energy is transferred to the target. [11] Before that, a British sniper in Afghanistan held the record at 2,475 meters (2,707yd; 1.538mi) using a .338 Lapua Magnum (8.5870mm) rifle. 12.7 x 99mm, APEI, M 02, "Advancements in Lightweight .50 Caliber Ammunition", "DoD Wants Bullet That Can Change Direction After Being Fired", "EXACTO Guided bullet demonstrates repeatable performance against moving targets 2904152 | weapons defence industry military technology UK | analyse focus army defence military industry army", "EXACTO Guided Bullet Demonstrates Repeatable Performance against Moving Targets", "Metal link M9 for cal. This justifies the strength of the snipers and their sturdy build for heavy operation. Mathematically, it is the ratio of a bullet's sectional density to its coefficient of form. And we know we have harped on this several times throughout the article, but we are going to talk regarding cartridge versus cartridge rather than round to round. As the 50 BMG bullet has a high ballistic coefficient, it is used for powerful sniper rifles. It still has more penetrating power than lighter weapons such as general-purpose machine guns, though it is significantly heavier and more cumbersome to transport. These are extremely large rounds that require heavy weapons as well as other equipment to shoot accurately. No spam. The 50 BMG does have several rounds that break the .9 and even 1.0 mark, but the 338LM is nothing to scoff at either. You can find an email form and contact information here. AP (ARMOR PIERCING) M2 On the other hand, 50 BMG is designed for machine gun operations, which belongs to 50 Cal. As we have done in previous sections, we are going to look at our ten selected rounds. Its a culmination of several factors including bullet energy, penetration, bullet expansion, and shot placement. Another factor that goes into a cartridges stopping power is the penetration of the bullet. ), but the ammunition did not exist. Caliber Multi: .50 BMG Application: Hunting . 50 BMG has a 12.7mm diameter and is also used in snipers and machine guns. A ballistic coefficient is a value that is assigned to a bullet type to signify how well it can cut through the air. Maybe even more so when looking at these two rounds. 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. The proof/test pressure is listed as 65,000psi (450,000kPa). Encased in Barrett head-stamped brass, every cartridge is loaded with noncorrosive powder and primers as well as a 661 gr projectile using state-of-the-art machinery. In some cases you might be surprised. 338 LM Federal MatchKing BTHP Gold Medal 250gr, 338 LM Nosler Trophy Grade AccuBond 300gr. FMBT bullets. In certain aspects and certain situations, sure, there are cartridges better suited to the task than others. PMC X-Tac Match .50 BMG Ammunition 10 Rounds 740 Grain Solid Brass Projectile 2830fps 50XM. The Bullet Has a Superb Ballistic Coefficient compared To Other 50 Caliber Bullets That Have separately Formed driving bands . Velocity is key for proper penetration and expansion, which is critical for hunting. This bullet is 0.50 in diameter and typically 2.25-inch long. Aaronthal Weapon Systems It has a .30-06 Springfield design with a long taper case wall for various types of weapons. . The longest recorded kill using a .50 BMG was over 2 miles away. These are excellent speeds for long range shooting, especially when shot from a rifle with the proper twist rate to stabilize them in flight. Besides military and police organizations, the .50 BMG has gained popularity in some civilian circles. The incredible energy of the 50BMG overshadows the .338 Lapua Magnum, which in its own right possesses a great deal of kinetic energy. Well discuss this topic more in the applications section. This is near impossible to handle accurately unless accessory gear is used to help absorb and stabilize the rifle. A high number means the bullet is more efficient at resisting air friction (negative acceleration). We will take a brief look at the origins and histories of these two cartridges and then jump into categories such as stopping power, trajectory, and even price among others. I love hunting, so I often have to deal with hunting equipment. A .50 BMG round can effectively disable a vehicle when fired into the engine block. Thank you. ShootersCalculator.com is in the process of being massively overhauled. Barrel Lengths & Velocities for the 50 BMG. Ballistic Coefficient is essentially a measure of air drag. Were not going to go too specific with the comparisons here. For two cartridges that are touted as extreme distance shooters, the ballistic coefficient is going to be an important factor for potential users. In ballistics, the ballistic coefficient ( BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. We are using computer data that was compiled from the manufacturers websites as well as from trusted ballistic calculators. 12.799mm Technical data", "Technical Manual Small-Arms Ammunition, TM9-1990, U.S. War Department", "SHOT Show 2006 New Rifles, Shotguns, Pistols Offer Enhanced Performance", "Weaponry: .50 Caliber Rifle Crime," GAO Office of Special Investigations letter", "CHAPTER 943 OFFENSES AGAINST PUBLIC PEACE AND SAFETY", "Are .50 BMG rifles legal in California? The rounds intended for machine guns are made into a continuous belt using metallic links. Military Applications: Note: We have selected two different 50 BMG loads to demonstrate here. 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. .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 Cartridge dimensions The 50 BMG 12.7 99 NATO cartridge has a capacity of 290 grains H2O (19 ml). Unsubscribe at any time. [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). I want this to be the best ballistic trajectory calculator out there. Ballistic Coefficient - BC of 0.364 seems to be way low, standard BC for Ball Ammo should be in the 0.650-0.670 range. [39] However, .50 BMG rifles registered prior to the enacted bans remain lawful to possess in California[37][40] and Connecticut. We suppose it all depends on the type of hunting you do, but if you plan on doing any spot and stalk, you better be in shape. However, Los Angeles banned this bullet round. It is inversely proportional to the negative acceleration a high number indicates a low negative acceleration. 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. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. How much energy is required to take down an animal varies and the amount that actually gets transferred to the target varies. This large amount of force is very destructive to surrounding tissue and organs. Our 50 BMG ammunition is ready for action. . We are measuring the bullet drop (inches) from 100 out to 1,000 yards. . 50 Cal 647 Grain Ball pulled bullets.
