Barrel Length inches 36 Ballistics Coefficient (G1) 0.707 Ballistics Coefficient (G7) 0.350 Sectional Density 0.362. The BC of a round also plays a large role in the trajectory of a round, which we will look at next. The TSX has gained worldwide recognition as one of the deadliest, most dependable bullets you can buy. Of course, how much penetration you need is going to depend on the game you are hunting. Caliber Multi: .50 BMG Application: Hunting . If you do not have a Shooting Chronograph, I strongly suggest you purchase one. 50 Caliber has different types of rounds, while 50 BMG is a particular one. Apr 23, 2011 #1 Does anyone know the B.C. 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. Sight Height (in) Must be a number greater than 0. We also hope that we have made clear that the BC is not a point for comparing which bullet is better or worse than others. The average chamber pressure in this round as listed in TM43-0001-27,[18] the U.S. Army Ammunition Data SheetsSmall Caliber Ammunition, not including plastic practice, short cased spotter, or proof/test loads, is 54,923psi (378,680kPa). In addition, these snipers will have less drift from the winds of the bullet. 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. The surface is dirt and water-resistant. A ballistic coefficient is a value that is assigned to a bullet type to signify how well it can cut through the air. It uses a boxer primer with a central ignition point. With modern firearms, the majority of centerfire rifle cartridges can be tolerated with regards to the recoil. When a bullet is fired from the barrel, it carries kinetic energy that upon impact is transferred to the target. Powder is matched carefully to each specific load for optimal pressure, velocity and consistent accuracy. To do this, we have selected several rounds for each cartridge we are comparing. In some cases you might be surprised. 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. 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. [citation needed], The U.S. Coast Guard uses .50 BMG rifles onboard armed helicopters to disable the engines on boats during interdictions. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. The guns that use these bullets were used to target troops to save from enemy guns. They are easily portable to shoot at great ranges with destructive forces. Ammunition is sold in 80-round cases. Informative, interesting and well written. During operation or simply game shootings, it can make a significant wound in cases of accidents. 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. 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. 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). ShootersCalculator.com is in the process of being massively overhauled. Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 BMG can exceed this normal BC. These are used by both civilians and military forces for various purposes. For the .50BMG, we would recommend the Hornady A-MAX Match 750gr round. Each cartridge is loaded with either Hornady A-MAX bullets, our high-performance boattail hollow points, or the new, radically superior ELD Match bullets. This large amount of force is very destructive to surrounding tissue and organs. They do have some pull marks. Fillable and printable Ballistic Chart 2023. It also has a strong recoil force as the cartridge is filled with powder. 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. Each cartridge is loaded with either Hornady A-MAX bullets, our high-performance boattail hollow points, or the new, radically superior ELD Match bullets. 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. As time goes, they are becoming more popular among shooters and hunters. For hunters, stopping power is a critical factor in choosing a certain cartridge. This is a hard hitting round with incredible range and power. 500 yds. Thus, to begin zeroing on an optically centered scope, you have to come down 30 minutes at the start. Generally, the heavier the projectile the better the BC, so most .22 pellets will have a better BC than .177, and most .25 pellets better than .22 and so forth. Basically, BC is a measure of how . The TSX was introduced in 2003 and has become Barnes' most popular hunting bullet. 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 higher the number, the less drag the projectile will experience. The incredible energy of the 50BMG overshadows the .338 Lapua Magnum, which in its own right possesses a great deal of kinetic energy. 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. They all can kill any game animal in the world. 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. Stringent quality control ensures proper bullet seating, consistent charges and pressures, optimal velocity, consistent overall length and repeatable accuracy. . Just for comparison of how intense the recoil energy is for these two cartridges, some common hunting rounds such as the .30-06 and .308 are generating recoil in the 20-26ft.lb range when using a 7lb rifle with the same conservative powder loads. You would be surprised how many of them have never given their rounds BC a thought. Looking at just the basic physics, a .50 bmg has a muzzle velocity of about 420 meters per second (1480 feet per second). It is a great investment if you want to get into long range shooting and will be especially useful if you handload. The term BMG means Browning Machine Gun. 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. 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. [14], Some civilians use .50 caliber rifles for long-range target shooting: the US-based Fifty Caliber Shooters Association holds .50 BMG shooting matches. DPMS LR-308 [Review]: The AR, Back to Basics. It runs on all modern Windows (Win98 and greater) computers. With the .338 Lapua Magnum vs .50 BMG, recoil takes on a bit more of an important role. For the 50BMG, we are not going to give a specific round. 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. 400 yds. Think of it paired with the energy of the bullet. Lets take it a step further and take a look at the rounds we have selected for comparison. 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. This ammunition usually contains Swedish brass and perfect military specifications. Even so, its difficult to compare the accuracy of two cartridges by the means that we have. . Ballistic Coefficient: 0.62 Bullet Weight: 661 gr Initial Velocity: 2750 fps Sight Height : 3 in Shooting Angle: 0 Wind Speed: 0 mph Wind Angle: 0 Zero Range: 100 yd Chart Range: 2600 yd Maximum Range: 7169 yd Step Size: 50 yd International Standard Atmosphere Altitude: Sea Level (0 ft) Barometric Pressure: 29.92 Hg Temperature: 59 F 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. 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. With that, you have a better chance at running into .338 LM rounds than a box of 50 BMG. [12][13], In addition to long-range and anti-materiel, the U.S. military uses .50 BMG weapons to detonate unexploded ordnance from a safe distance. . Effect? A lot of competitions wouldnt allow a .50 caliber round, but if you just enjoy taking shots upwards and beyond 1,000 yards, the 50 BMG is hard to beat. Maybe even more so when looking at these two rounds. Looking at it another way, if one is off by 5%, they're probably all off the same amount, making our comparison valid. On 14 April 2001, 19-year old Senior Airman Jennifer Donaldson, from the Illinois Air National Guard, made history. Its ballistic coefficient is 1.050. This American Eagle ammunition was produced by Lake City Arsenal to NATO specifications. It is when we move out from this marker that we begin to see a general trend between the 338 LM vs 50 BMG. 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. 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. It should already be clear that the difference just from the bullet diameter is quite dramatic. [38] Connecticut specifically bans the Barrett 82A1 .50 BMG rifle. and long-range bullets generally range from 0.5 all the way up to 1.0 with the .50 BMG! You might be asking yourself if the velocities shown here are enough for proper expansion of such a large bullet such as the .50cal. Usually, a 50 cal round has a diameter of 12.7 mm diameter. The bullet type and powder make the recoil force different between bullets. While it is one of the more expensive rounds on our list, you are paying for incredible performance that comes close to matching hand loaded rounds from the experts. 50 BMG (12.799) 647 Grain API Match Grade Ammunition This ammunition is manufactured in the USA by FedArm. Some big, heavy, and efficient bullets like the .50 BMG can have a ballistic coefficient greater than one, but that topic is for another day. The difference between the two rounds is as followed with the 50BMG showing a flatter trajectory. 50 BMG Ballistic Coefficient. As for powder charges, we used conservative numbers for each round based on the hand loading specifications from Nosler. Other than armed forces, civilians use this bullet round for target shooting and sports. 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. Retail Price: $478.50. Well, for 50 BMG, you're looking at $11-$16/round for military surplus ammo. Thank you. This is useful to get a legalized firearm with licenses. These include heavy stopping power that can be carried over incredible ranges. Calculating Trajectories . Joined Feb 9, 2010 Messages 6. Since the .50 BMG (23.00 23.33 g tungsten with muzzle velocity of 4,000 ft/s (1,219 m/s)) is very large it needs heavy weapons to support it. 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. 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). 338 LM Federal MatchKing BTHP Gold Medal 250gr, 338 LM Nosler Trophy Grade AccuBond 300gr. Regardless of what youre using your rifle for and regardless of the cartridge its chambered for we are all going to be interested in its ballistic performance. Since 50 BMG cartridges are unique, these have a limited number of sniper rifles built with adequate quality. Both 50 BMG rounds leave the muzzle with over 13,000 ft-lbs of kinetic energy compared to about 4,700 ft-lbs for the 338. The two most important variables are the Initial Velocity and the Ballistic Coefficient. According to the American Rifleman: "Actually, the Browning .50 originated in the Great War. They are both quality handguns, but their makers have taken two very different approaches to the designs. Within the United Kingdom, it is legal to own a bolt action .50 BMG rifle with a section 1 Firearms Certificate. It has the velocity, the BC, and the trajectory to make shots of even 1,500 yards. 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. To handle these rounds in the field, youre going to have to haul around a 30+lb rifle. [35], In the United States, Washington, D.C. disallows registration of .50 BMG rifles, thus rendering civilian possession unlawful. It couldnt be more clear that the 50BMG carries exponentially more kinetic energy with it than the .338 LM rounds. Our .50 BMG ammunition is ready for action.
