[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. .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 During operation or simply game shootings, it can make a significant wound in cases of accidents. [citation needed], The U.S. Coast Guard uses .50 BMG rifles onboard armed helicopters to disable the engines on boats during interdictions. Excellent quality, and great customer service from Dave Moore of Spider Firearms. From a hunting perspective, the advertised ballistic data confirms that all three cartridges have both the necessary sectional density (SD) and initial muzzle energy for both medium and large game hunting applications. 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. Even after the differences between 50 Cal vs 50 BMG, we see that they are quite similar in various features. An upgraded variant of the M2 Browning HB machine gun used during World War II is still in use today. The email address you entered is not valid. The .50 BMG (12.799mm NATO) cartridge has a capacity of 290gr (19g). Re: 50 BMG goes subsonic at 1500 Yards? Military Applications: Note: We have selected two different 50 BMG loads to demonstrate here. Apr 23, 2011 #1 Does anyone know the B.C. The cartridges have two separate links of the machine gun selected. No spam. When we look at the graph, it is quite a stark contrast between cartridges. In ballistics, the ballistic coefficient is used to measure the ability of something to withstand air resistance. Fill, sign and download Ballistic Chart online on Handypdf.com It might not compete with some hand loaded cartridges, but you cant get much better when it comes to a factory load. 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. It has a large cartridge used in anti-material for longer ranges. Check TopScopesfor Barrett.50 Cal. Rifles chambered for the .338 LM are a bit heavy to haul around the backcountry for most people, but it is much more manageable than a rifle chambered for a .50 BMG. . The projectiles are high quality hand pulled 647 grain M8 API projectiles which have been cleaned, resized, and inspected before loading. The less a bullet drops during its flight, the easier it is to make adjustments for longer distance shots. . Still, by comparing the recoil energies, it will translate loosely into what you feel. Usually, a 50 cal round has a diameter of 12.7 mm diameter. Any round from this bullet produces between 10,000 and 15,000 foot-pounds force muzzle energies. As far as the BCs go for these two cartridges, both show phenomenal numbers. The ballistic coefficient of the Barrett 50 BMG bullet is 0.64. This is why they fit perfectly to any automatic or belt-fed snipers, machine guns, or pistols designed for this cartridge. If you have any feedback or question about my articles, please submit it here, it's always appreciated! The range and terminal ballistics of the .338 LM were such that its use could fill several niches in civilian use including long range precision shooting and big game hunting. Military Requirement: due to the rounds being from Lake City Ammunition . Full Metal Jacket, with boat tail and cannelure. I love hunting, so I often have to deal with hunting equipment. There is no doubt that both are designed exclusively for successful performances in the field. Like most cases, there are better performing rounds for each cartridge type, but on average, the 50 BMG rounds excel in this category, and that distinction becomes clearer the greater the distance. The surface is dirt and water-resistant. The 338 LM was designed and produced in the late 1980s. Special Offer: Join our private community and get exclusive gun deals, handpicked gear recommendations and updates on law changes, every day! Even so, computer generated data is a proven and safe means for comparing two cartridges as we will do here. When a bullet is fired from the barrel, it carries kinetic energy that upon impact is transferred to the target. About the previous point, a clean kill means you are not going to have to track a wounded animal sometimes a couple hundred yards and possibly in the dark and cold. I want this to be the best ballistic trajectory calculator out there. While the muzzle energy of popular bullets such as 30-06 Springfield is less than 300-foot pound-force, the muzzle velocity of 50 BMG ranges between 10000 to 15000-foot pound-force. 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. A high number also means that the bullet will retain MORE velocity as it moves down range. Apart from machine guns, snipers and anti-materiel rifles use this cartridge. It couldnt be more clear that the 50BMG carries exponentially more kinetic energy with it than the .338 LM rounds. While it is only two factors that go into stopping power, they are the best for comparing two cartridges besides comparison in the field. Zero Range (yd) This is because the bullet is very large, so the wound it makes is also large and deep, but still curable. [14], Some civilians use .50 caliber rifles for long-range target shooting: the US-based Fifty Caliber Shooters Association holds .50 BMG shooting matches. Lets take a look at the velocities of each round from the muzzle out to 1,000 yards. 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. Keep in mind this is an approximation and although it is quite accurate it should never replace first-hand experience of shooting your specific firearm and ammunition to determine the bullet drop and windage at different ranges and conditions. It is inversely proportional to the negative acceleration a high number indicates a low negative acceleration. The bullet length, shape, and weight all positively contribute to a much higher BC than the 50 Beowulf bullet. 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. This American Eagle ammunition was produced by Lake City Arsenal to NATO specifications. There is a very small circle of people out there who have turned to the 50BMG for hunting purposes. 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. A few of these include the bullet design (spitzer, boat tail, flat nose, etc.) We do know that the recoil energy is nearly double even with the 50BMG using a 30lb firearm compared to the 15lb for the 338. Granted, if youre firing these rounds, you most likely have gear that aids in absorbing the recoil and stabilizing the firearm. There are several variants of this 50 caliber round. This is why it is used in heavy-duty shootings. 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. The higher the number, the less drag the projectile will experience. But it differs from other types of 50 caliber bullet rounds. The .30-06 Springfield, the standard caliber for American soldiers in both World Wars and a popular caliber amongst American hunters, can produce muzzle energies between 2,000 and 3,000 foot-pounds force (3,000 and 4,000J). 50 BMG 750 gr A-MAX Match Item #8270 | 10/Box We carefully select every component to ensure uniformity, then load to exacting specifications to provide pinpoint accuracy. Since a .50 caliber bullet is manufactured with a solid metal surface and core, it is very powerful. While the .338 rounds have a much smaller diameter than the huge .50 cal rounds, the exponentially heavier bullet weights of the 50BMG rounds make up for the large size. Its ballistic coefficient is 1.050. The ability to hit distant targets is . Any armor with composite metal foam is strong to stop a 50 cal bullet. DPMS LR-308 [Review]: The AR, Back to Basics. Us has made 50 BMG the standard as the largest bullet round in terms of shell size. With modern firearms, the majority of centerfire rifle cartridges can be tolerated with regards to the recoil. Muzzle Velocity - 2,952 is a screaming velocity, HSM AMAXs run around 2,680, and Barrett Ball is around 2,750. You can find an email form and contact information here. Lets first take a look at the recoil energy (ft.lb) of these two rounds in general. The higher the velocity, the flatter the bullet will shoot, with less wind drift, more energy when it reaches the target, and an extended . Most importantly, they are designed to reduce the bullets recoil. 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 ). There are some options for bulk purchase which can save you some money in the long run. 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. 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 So , lets get down to business. My first deer at the age of 45 I joined the deer hunting fraternity a little late, but the desire to hunt has always been there. Both are considered powerful and unique bullet rounds. 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. In this way, the user can know how much recoil the 50 BMG round has due to impact. 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! [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). Your email address will not be published. We have compiled the ballistic coefficients for all ten rounds and graphed them here. . New reloading data must be opened as a PDF document in an up-to-date compatible PDF viewer. 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. Price Per Round: $2.90. However, bullets shot from pistols are slower as the gunpowder takes longer to burn. The majority of these people are using the cartridge for long range hunting on large game such as elk, moose, and even dangerous game. A 50 caliber bullet is measured to be an inch. We also know that this bullet can enter very tough materials easily. Three distinct and non-compatible metallic links have been used for .50 BMG cartridge belts. 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. 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. 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. Typically, long range rifle bullets have a ballistic coefficient of 0.5 (G1) or above. 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. The rounds intended for machine guns are made into a continuous belt using metallic links. [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.
