[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. Both of these cartridges are capable of accuracy at extreme distances, and both have enormous stopping power. In ballistics, the ballistic coefficient ( BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. We will shortly look at the averages of these cartridges, but want to point out again that while some of the numbers might seem like drastic differences, and technically they are, its critical to observe the individual rounds, specifically the .338 LM. Because this is computer generated data and because each rifle has its own personality, the actual numbers that are going to come from firing one of these rounds from your rifle, the numbers shouldnt be too far off but we wanted to make it clear that these numbers are not set in stone. In this way, the user can know how much recoil the 50 BMG round has due to impact. All data created using our free ballistic calculator. While there are parties who will place one cartridge over the other, we are not looking to do that in our comparisons. The 50 BMG is the winner of this section..50 BMG vs .50 Beowulf: Stopping Power. Some of them can also be semi auto-loading guns. 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. You will be sent the quantity of bullets that are ordered. It has a large cartridge used in anti-material for longer ranges. It answered a lot of my questions. 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 . cartridge. We also see that all rounds for both cartridges leave the muzzle at more than 2,500fps and maintain supersonic speeds out to the 1,000-yard mark. ?Ballistic Coefficient: 1.070?Sectional Density: 0.412?Special attention should . It can shoot up to ranges of 330 yards and floats in the air for about seven seconds, before dropping to the ground. 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. Get my premium 550+ pages handbook that compares all cartridges, for free (worth $199!) [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. As we mentioned above, firing these rounds often requires heavy firearms and other pieces of gear that help negate this recoil. Where to Buy Ammo Online [Complete 2021 Guide], Best Gun Cleaning Kits [AR-15, Pistol & Universal], Best Shooting Gloves [Hands-On Tested, 2021 Update], Best Universal Red Dot Sights [Hands-on Review]. The mass is one of the bullets. I love hunting, so I often have to deal with hunting equipment. . . We have compiled the ballistic coefficients for all ten rounds and graphed them here. Beretta 3032 Tomcat [Review]: A Worthy Self-Defense Pistol? 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. Of course, how much penetration you need is going to depend on the game you are hunting. Its because 90% of their shots are coming at 250 yards or less. As far as availability goes for the 50 BMG vs 338 Lapua Magnum, both are going to be harder to come by then smaller, more traditional hunting and target cartridges. PMC X-Tac Match is developed around several award winning loads replicating performance down to a tee. [30][31] The M15-series metal "push-through" links were used in the M85 machine gun. The rounds intended for machine guns are made into a continuous belt using metallic links. Re: 50 BMG goes subsonic at 1500 Yards? 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. So, here is a table below: During the war, 50 calibers were used against light armor vehicles and aircraft due to their penetration power. The higher the number, the less drag the projectile will experience. Fill, sign and download Ballistic Chart online on Handypdf.com In our minds, there is no one cartridge that is above and beyond better than another. The auctioneer claims that it is only one of twelve built and the only other known example resides at the Ford Benning sniper school. The physics and theories behind the ballistic coefficient can get quite cluttered and complicated, though we highly recommend diving into the subject when you have the time. [43] Writing for the Marine Corps Gazette, Maj Hays Parks states that "No treaty language exists (either generally or specifically) to support a limitation on [the use of .50 BMG] against personnel, and its widespread, longstanding use in this role suggests that such antipersonnel employment is the customary practice of nations." Though they also carry quite a significant amount more powder and as we saw previously, you pay for it with the recoil. Most people who are using a .50 BMG are not hunting and are looking at extreme distance shooting. Our .50 BMG ammunition is ready for action. It has a diameter of .50 inches, with a casing length of 99 mm and an overall length of 138 mm. 50 BMG Ballistic Coefficient. Us has made 50 BMG the standard as the largest bullet round in terms of shell size. The two most important variables are the Initial Velocity and the Ballistic Coefficient. Putting it all Together 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. Typically, long range rifle bullets have a ballistic coefficient of 0.5 (G1) or above. It comes in different types like tracer, armor-piercing, usual ball, incendiary, and sub-caliber rounds. 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. This is the Ferret .50; a top-end attachment to an AR15 lower. In regards to ballistics, the .50 BMG has a bigger, heavier bullet that delivers a reliable killing shot at ranges up to 3300 yards and take down medium-sized game at these incredible ranges.. To do this, we have selected several rounds for each cartridge we are comparing. Since 50 BMG bullets are powerful, they can enter through a body part with force. only today ! The .50 BMG is a bigger, heavier bullet that delivers a reliable killing shot up to an astounding range of about 3300 yards. Under STANAG 4383, it is a standard service cartridge for NATO forces as well as many non-NATO countries. For a lot of cartridge comparisons we have done, recoil is usually not that huge of an issue. To gain more knowledge and quick learning, a comparison table is always the best form. While it travels in the air, it causes a shockwave which is equally dangerous to make a severe wound. 50 BMG ammo is a large, round sniper bullet. Sometimes, the wound may be fragile, but it may also get fatal. 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 are not going to sit and mess around with the short range trajectory. 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. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. 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. . and long-range bullets generally range from 0.5 all the way up to 1.0 with the .50 BMG! for the the South African 690gn. In some cases, it is used to detonate mounted guns or cannons. Machine guns use it as a continuous belt of rounds. And this is simplifying the topic since we are leaving out expansion, which is also going to play a role in penetration. But, if you need the performance, its just something you have to deal with, especially if you dont reload. Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 BMG can exceed this normal BC. Pull-out cloth belts were also used at one time, but have been obsolete since 1945. Still, we think that we can get some valuable information by examining the kinetic energy associated with our various rounds as the move from the muzzle down range to 1,000 yards. This is near impossible to handle accurately unless accessory gear is used to help absorb and stabilize the rifle. Bullet velocity is a very important ingredient of successful long-range shooting. 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. Barrel Lengths & Velocities for the 50 BMG. Its ballistic coefficient is 1.050. The energy is only part of the equation to stopping power, but it is an important one to examine nonetheless. . Inside the cartridge consists of a core made of manganese molybdenum steel, a point filler, and a seal of the lead-antimony base. The .50 BMG (12.799mm NATO) cartridge has a capacity of 290gr (19g). Similar to snipers, 50 BMG pistols are also made of hard materials to support the powerful cartridge. We are measuring the bullet drop (inches) from 100 out to 1,000 yards. They wanted a heavy projectile at 2700 feet per second (f.p.s. To test the power, we see that a .50 BMG cartridge can cross the .9 mark, with a flat projectile motion. Dont let the comparison to the 50BMG throw off your judgment as to what this cartridge can do. Any thoughts on where I can find an unbiased comparison? Its really the only way either of these rounds can be fired accurately. When it comes to hunting, there are great options for the .338 LM. 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. They are of premium build to make precise targets with less recoil. However, bullets shot from pistols are slower as the gunpowder takes longer to burn. Federal Ammunition 50 BMG Ballistic Data. Where there are variables, we try to keep them as uniform as possible, but for some cases, it only makes sense to change these variables based on the cartridges. We carefully select every component to ensure uniformity, then load to exacting specifications to provide pinpoint accuracy. Obviously, this would be an advantage for shooting round out at 1,000 yards or more. Huge bullets with enough powder to send them downrange at supersonic speeds are going to produce enough kick to knock you down. Your information will never be shared and you can unsubscribe with one click at anytime. The higher the velocity, the flatter the bullet will shoot, with less wind drift, more energy when it reaches the target, and an extended . 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 is a great investment if you want to get into long range shooting and will be especially useful if you handload. 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. 2023 Optics Bible - WordPress Theme by Kadence WP, 50 Cal Vs. 50 BMG : Which One To Choose [ Know Differences], 223 vs 3006: What to Choose After In-Depth Comparison. We also want to note that while we are taking each category and looking at them independently, all of these categories are interwoven with each other, including recoil and stopping power that we will look at shortly. Price Per Round: $2.90. 50 Cal 647 Grain Ball pulled bullets. The max I have ever seen anyone run is around 3,000 and that is considered to be hot. This includes the velocity, the BC, and the trajectory of the round. The Army then returned to John Browning for the actual gun. Hornady Manufacturing makes the best cartridges for 50 BMG Ammunition 10 Rounds. This is why they fit perfectly to any automatic or belt-fed snipers, machine guns, or pistols designed for this cartridge. The TSX has gained worldwide recognition as one of the deadliest, most dependable bullets you can buy. Basically, BC is a measure of how . It has the velocity, the BC, and the trajectory to make shots of even 1,500 yards. 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. With ME of over 1,200ft.lb and and ME of over 5,000ft.lb at 1,000yds, there are no restrictions on the type of game you can hunt. However, sectional density, the relationship between . 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! 300 yds. Ballistics Coefficient (abbreviated "BC") is a bullet's ability to resist air friction and stay airborne. Gun deals, hand's on reviews, educational content and news on law changes, every day! What you might be looking for is how these rounds behave in flight, which is what we will look at next. [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. A ballistic coefficient is a value that is assigned to a bullet type to signify how well it can cut through the air. 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. How much energy is required to take down an animal varies and the amount that actually gets transferred to the target varies. Lets first take a look at the recoil energy (ft.lb) of these two rounds in general. This will differ with various models. Love Ammo? 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. As the 50 BMG bullet has a high ballistic coefficient, it is used for powerful sniper rifles. The guns that use these bullets were used to target troops to save from enemy guns. The primary military use of this round is in the M2 Browning machine gun and anti-materiel rifles such as the Barrett M82. Both of these cartridges are going to produce a tremendous amount of recoil. The ballistic coefficient or measure of drag for the .50 BMG is 1.05 which, is higher than any other commercially available around. 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. You might be strictly a hunter or strictly a competition shooter, but the majority of us are a mixture of both. FMBT bullets. '"[5], The American Rifleman further explains that development was "[r]eputedly influenced by Germany's 13.2x92 mm SR (.53-cal.) . If you do not have a Shooting Chronograph, I strongly suggest you purchase one. We are using computer data that was compiled from the manufacturers websites as well as from trusted ballistic calculators. Instead, we want to take an unbiased look at the data in several ballistic and other performance category and compare them. 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. During wartime, especially WW2, the US coast guard, and military used 50 BMG rifles towards helicopters. Think of it paired with the energy of the bullet. The proof/test pressure is listed as 65,000psi (450,000kPa). There is a very small circle of people out there who have turned to the 50BMG for hunting purposes. The Heat Shield tip on the ELD Match bullet creates the perfect meplat and outperforms BTHP bullets. In some cases you might be surprised. Lets take a look at the velocities of each round from the muzzle out to 1,000 yards. Be aware you may consider some of them unusable. This bullet weighs much less even with the large size. Those values would be correct if you were shooting the ammo out of a "military weapon system" at the upper end of the velocity spectrum in the 3,000 fps range. So, lets focus on the long range trajectory for these two cartridges. [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. DARPA (Defense Advanced Research Projects Agency) contracted with Teledyne Scientific Company to develop the EXACTO program, including a .50-caliber guided bullet. A sniper consists of the bipod, handle, brake, and removable magazine. Access features of the Reloading Handbook on your mobile device with the Reloading App. They are widely used by civilians as well as military forces. 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. 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 trajectory is what just about every hunter or competitive shooter of every skill level will be interested in when comparing two different cartridges. Any round from this bullet produces between 10,000 and 15,000 foot-pounds force muzzle energies. 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. After four seconds, the bullet will have dropped around 256 feet. 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. But, one can also survive the wound from a 50 BMG shot if it isnt fatal. Muzzle Velocity - 2,952 is a screaming velocity, HSM AMAXs run around 2,680, and Barrett Ball is around 2,750. A very interesting and well written article by an educated man with a surprising background. For hunting, a lot of hunters want expansion to cause a larger wound and more damage. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. For comparison, a similar monolithic bullet in .50 BMG usually maxes out around 800 grains at 2,900 fps. What is the best scope for a .50 BMG and what is the strongest 50 BMG? Brands like Smith & Wesson, Magnum Desert Eagle, Magnum Research, Guncrafter Industries, Ruger Super, Safety Harbour, etc create the best pistols for 50 BMG. 50 BMG (12.799) 647 Grain API Match Grade Ammunition This ammunition is manufactured in the USA by FedArm. Both cartridges have the velocity needed for long range shooting though the 50BMG seems to show slightly higher velocities and this gap between the cartridges widens as the rounds move downrange. 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 ). Both are considered powerful and unique bullet rounds. Hi! Heavier bullets with the same diameter are going to penetrate deeper than lighter rounds with the same diameter. 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. They can easily enter through light armors and hit targets. 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. KelTec Sub 2000 [Review]: Best PCC Firearm? On the other hand, 50 BMG is designed for machine gun operations, which belongs to 50 Cal. The .50 BMG cartridge is also produced commercially in a wide range of specifications, including armor piercing, tracing, and incendiary. 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. Usually with the sniper comes some accessories to clean and use effectively. Sign up to receive new product announcements, special offers, and the annual product catalog. This is especially true if that bullet also has a high ballistic coefficient. This is why their weapons are hard to find and limited in number. However, the strength depends on the sturdiness and power of the rifles used for this bullet. The 50 BMG rounds are quite impressive with BCs all above the .7 mark and one round coming in with a 1.05BC. Its also not the most expensive .338 LM factory load that is available. During operation or simply game shootings, it can make a significant wound in cases of accidents. These are excellent speeds for long range shooting, especially when shot from a rifle with the proper twist rate to stabilize them in flight.
