Still, some might be unfamiliar, so we want to touch on what exactly a ballistic coefficient is before we move on to the comparison. Of course, looking at averages might not be fair as there are .338 LM rounds that carry similar or even higher velocities than some 50BMG rounds. For simply comparing two different cartridges, we are going to omit it for the sake of clarity. Although 50 cal is a very penetrating bullet, research has found something to stop it. How To Read Remington Nylon 66 Serial Number Year Codes? How much energy is required to take down an animal varies and the amount that actually gets transferred to the target varies. 500 yds. The 7.62 is the "screw you way over there" round. 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. Even so, its difficult to compare the accuracy of two cartridges by the means that we have. Lets take a look at the velocities of each round from the muzzle out to 1,000 yards. While it is only two factors that go into stopping power, they are the best for comparing two cartridges besides comparison in the field. Availability: Out of Stock. The 338LM rounds under our specifications have recoil energies ranging between 29 and 33ft.lb. Bullet mass/type Velocity Energy; 647 gr (42 g) Speer: 3,044 ft/s (928 m/s) 13,310 ftlbf (18,050 J) 655 gr (42 g) ADI: 3,029 ft/s (923 m/s) Done (0.63 seconds). 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. Lake City 50 BMG Ammo Details. 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. As the 50 BMG bullet has a high ballistic coefficient, it is used for powerful sniper rifles. It might not compete with some hand loaded cartridges, but you cant get much better when it comes to a factory load. For a lot of cartridge comparisons we have done, recoil is usually not that huge of an issue. Gun deals, hand's on reviews, educational content and news on law changes, every day! Pull-out cloth belts were also used at one time, but have been obsolete since 1945. If you have any feedback or question about my articles, please submit it here, it's always appreciated! A high number also means that the bullet will retain MORE velocity as it moves down range. SHTF 50: Safety Harbor's .50-Cal Upper Conversion for AR-15s If youre looking to choose between heavy, hard hitting, and far flying cartridges such as the .338 LM and 50 BMG we are pretty confident that you are well aware of the ballistic coefficient. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. Bullet velocity is a very important ingredient of successful long-range shooting. You make up some cartridges and we'll do some shooting. 50 BMG Ballistic Coefficient. DARPA (Defense Advanced Research Projects Agency) contracted with Teledyne Scientific Company to develop the EXACTO program, including a .50-caliber guided bullet. You might be strictly a hunter or strictly a competition shooter, but the majority of us are a mixture of both. It possesses the ballistic performance to reach out to game at a distance and still carries the energy needed to aid in bringing down big game cleanly. It also has a strong recoil force as the cartridge is filled with powder. Trajectory follows a similar trend where both show very flat trajectories, though the 50 BMG excels in this category as well. [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. How important the ballistic coefficient is with shooters often depends on the distance of shots they are taking. Since a 50 cal bullet can slice through a body without protective armor, it can also kill someone. Unsubscribe at any time. Even so, computer generated data is a proven and safe means for comparing two cartridges as we will do here. 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. 300 yds. They can easily enter through light armors and hit targets. 50 BMG is one of the types of 50 caliber cartridges used for 50 BMG machine guns. What is ballistic coefficient (BC)? However, the strength depends on the sturdiness and power of the rifles used for this bullet. This is the best ballistic coefficient of any bullet to date. During World War II the .50 BMG was primarily used in the M2 Browning machine gun, in both its "light barrel" aircraft mount version and the "heavy barrel" (HB) version on ground vehicles, for anti-aircraft purposes. But a higher ballistic coefficient doesn't necessarily mean it is a better bullet. It saw service with the military in both Afghanistan and Iraq and is still in use with military personnel today, but it has also found a loyal following among civilians. 300 yds. These are used by both civilians and military forces for various purposes. By doing this, perhaps we can tease apart in which situations one cartridge might be better suited over the other. [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. 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. We dont have a single set of data we can look at to determine stopping power. The TSX has gained worldwide recognition as one of the deadliest, most dependable bullets you can buy. 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. [39] However, .50 BMG rifles registered prior to the enacted bans remain lawful to possess in California[37][40] and Connecticut. In certain aspects and certain situations, sure, there are cartridges better suited to the task than others. Federal Ammunition 50 BMG Ballistic Data. R. remrifle333 Member. 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. To gain more knowledge and quick learning, a comparison table is always the best form.

In addition to the usual tables and graphs of drop, velocity, and windage, Modern Ballistics has these unique features: Sight Angle. Before we get into our comparisons, there is one more note that we would like to make. 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. Zero Range (yd) They should show closer accuracy between each other however, because the form factor is constant. Usually with the sniper comes some accessories to clean and use effectively. It has a ballistic coefficient of .730. Regardless, a round with a higher BC is going to maintain a higher BC than a second bullet since both would be effected in the same way. They are widely used by civilians as well as military forces. Thank you.

I love hunting, so I often have to deal with hunting equipment. Apr 23, 2011 #1 Does anyone know the B.C. No spam. [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." Copyright 2023 ShootersCalculator.comALL rights reserved. The SD comes from the diameter of the bullet and the weight of the bullet. 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. Its also not the most expensive .338 LM factory load that is available. Spitzer. Introducing the latest products from the worldwide leader in ammunition. 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 So, here is a table below: During the war, 50 calibers were used against light armor vehicles and aircraft due to their penetration power. 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. When a bullet is fired from the barrel, it carries kinetic energy that upon impact is transferred to the target. We went conservative with the powder weight because these are factory loads and are not normally loaded near max capacities. In ballistics, the ballistic coefficient is used to measure the ability of something to withstand air resistance. 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. But they are also dangerous and must be used with caution during operations to avoid fatalities. 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. 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. For hunters, stopping power is a critical factor in choosing a certain cartridge. Usually, these can leave a severe wound. Velocity fps: 2940: 2806: 2677: 2551: 2428: 2309: Energy ft lbs: 12666: 11541: 10499: 9534: Any round from this bullet produces between 10,000 and 15,000 foot-pounds force muzzle energies. It runs on all modern Windows (Win98 and greater) computers. 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. A ballistic coefficient is a value that is assigned to a bullet type to signify how well it can cut through the air. The primer type specified for this ammunition is Boxer primer that has a single centralized ignition point (US and NATO countries). The bullet type and powder make the recoil force different between bullets. So when game time comes make sure you are ready and enjoy the accuracy of Federal American Eagle 50 BMG ammunition!

Full Metal Jacket, with boat tail and cannelure. The longest recorded kill using a .50 BMG was over 2 miles away. 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. only today ! He wanted the round to be used in a machine gun, and wanted the machine gun to be based on a scaled-up version of the M1917 Browning. The time for a .50 calibre bullet to travel one mile at a constant speed of 1400feet per second is around four seconds. The difference between the two rounds is as followed with the 50BMG showing a flatter trajectory. It is made a standard bullet for important army forces. The .50 BMG is a bigger, heavier bullet that delivers a reliable killing shot up to an astounding range of about 3300 yards. [15], A common method for understanding the actual power of a cartridge is comparison of muzzle energies. The two most important variables are the Initial Velocity and the Ballistic Coefficient. The 50 BMG is the winner of this section..50 BMG vs .50 Beowulf: Stopping Power. . Can a 50 cal rip your arm off? Still, by looking at the sectional density (SD) of the rounds, we can get an idea of how well these different bullets can penetrate and gives us a basis for comparison. The energy is only part of the equation to stopping power, but it is an important one to examine nonetheless. 50 BMG basic cartridge dimensions-All sizes in inches (in). Barrel Length inches 36 Ballistics Coefficient (G1) 0.707 Ballistics Coefficient (G7) 0.350 Sectional Density 0.362. This bullet is 0.50 in diameter and typically 2.25-inch long.
