Doppler radar measurement results for a lathe turned monolithic solid .50 BMG very-low-drag bullet (Lost River J40 .510-773 grain monolithic solid bullet / twist rate 1:15 in) look . The ballistic coefficient or measure of drag for the .50 BMG is 1.05 which, is higher than any other commercially available around. So, here is a table below: During the war, 50 calibers were used against light armor vehicles and aircraft due to their penetration power. This weapon was used by other snipers, and eventually purpose-built sniper rifles were developed specifically for this round. 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. This justifies the strength of the snipers and their sturdy build for heavy operation. [30][31] The M15-series metal "push-through" links were used in the M85 machine gun. It excels in all of the ballistic categories that we have covered in this article. Teamed with Colt, he produced prototypes ready for testing and, ironically, completed them by Nov. 11, 1918the Great War's end. 50 Cal is generally known as the bore and the nominal bullet diameter. The ballistic coefficient of the Barrett 50 BMG bullet is 0.64. 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. Be aware you may consider some of them unusable. Factory loads for civilian purchase are limited with most of the available rounds coming with bullet weights between 650 and 750gr. Instead, we want to take an unbiased look at the data in several ballistic and other performance category and compare them. When we look at the graph, it is quite a stark contrast between cartridges. The 338LM rounds under our specifications have recoil energies ranging between 29 and 33ft.lb. So there is a fine line a lot of hunters try to walk when it comes to penetration. Besides military and police organizations, the .50 BMG has gained popularity in some civilian circles. ShootersCalculator.com is in the process of being massively overhauled. No spam. What is the best scope for a .50 BMG and what is the strongest 50 BMG? In this way, the user can know how much recoil the 50 BMG round has due to impact. Cartridge dimensions The 50 BMG 12.7 99 NATO cartridge has a capacity of 290 grains H2O (19 ml). That all said, there are deals out there. My problem is that the upper came with a 30 minute rail. We are using computer data that was compiled from the manufacturers websites as well as from trusted ballistic calculators. 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.

The time for a .50 calibre bullet to travel one mile at a constant speed of 1400feet per second is around four seconds. The common rifling twist rate for this cartridge is 1 in 15 in (381 mm), with 8 lands and grooves. To be able to push such large bullets to speeds that make them useful is going to take a good deal of powder and both have the casings to hold it. 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. These are excellent speeds for long range shooting, especially when shot from a rifle with the proper twist rate to stabilize them in flight. Higher velocities, with a stable bullet, also aid in long range performance, which is critical for both hunting and competition shooting. The .50 BMG cartridge is also produced commercially in a wide range of specifications, including armor piercing, tracing, and incendiary. The Spitzer is a very popular and aerodynamic bullet shape. As you can imagine, the bigger the game, the more energy you are going to need to cause enough damage for a clean kill. The .338 Lapua Magnum has a much shorter history than the other cartridge we will be examining in this article. Calculating Trajectories . A very interesting and well written article by an educated man with a surprising background. 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. I was also surprised with thebackground. When this is the case, we will be sure to make it clear what we are doing. After four seconds, the bullet will have dropped around 256 feet. The long range (over one mile) between firing position and target allows time for the sniper to avoid enemy retaliation by either changing positions repeatedly, or by safely retreating. Mathematically, it is the ratio of a bullet's sectional density to its coefficient of form. We went conservative with the powder weight because these are factory loads and are not normally loaded near max capacities. The AccuBond bullet used is perfect for the proper expansion needed while not sacrificing penetration for large game animals. The difference between the two rounds is as followed with the 50BMG showing a flatter trajectory. It couldnt be more clear that the 50BMG carries exponentially more kinetic energy with it than the .338 LM rounds. Before we get into our comparisons, there is one more note that we would like to make. I agree with Michael. By sticking with this 120-year-old non-aerodynamic standard, bullet companies ensure their BCs will be as large as .

Loaded specifically for precision big bore rifles, a wide variety of ammunition is available, including ball, tracer, armor-piercing, incendiary, and A-MAX rounds, with accuracy being priority number one. To make it as accurate as possible, it is important that you input the most accurate information that represents shooting conditions, your firearm, and cartridge. 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. A bull moose needs a bullet that can hold together and penetrate deeper than a bullet that is going to be used for whitetail. 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. 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. The caliber depends on the barrel diameter bore of the bullets guns. [38] Connecticut specifically bans the Barrett 82A1 .50 BMG rifle. 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. 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. How much energy is required to take down an animal varies and the amount that actually gets transferred to the target varies. This is the Ferret .50; a top-end attachment to an AR15 lower. At present, some US law enforcement use 50 BMG weapons, as well as snipers. When it comes to hunting, there are great options for the .338 LM. Stringent quality control ensures proper bullet seating, consistent charges and pressures, optimal velocity, consistent overall length and repeatable accuracy. The 50 BMG rounds range from 72 to 87ft.lb of recoil energy. only today ! Re: 50 BMG goes subsonic at 1500 Yards? For two cartridges that are touted as extreme distance shooters, the ballistic coefficient is going to be an important factor for potential users. DPMS LR-308 [Review]: The AR, Back to Basics.

Since 50 BMG cartridges are unique, these have a limited number of sniper rifles built with adequate quality. The guns that use these bullets were used to target troops to save from enemy guns. To put this into perspective, the 750 gr A-MAX load has essentially the same kinetic energy at 1,500 yards as a 300 Winchester Magnum has at the muzzle. On the other hand, 50 BMG is one of the various types of 50 Cal. There's a reason militaries worldwide still use a 50 BMG bolt-action rifle for sniping. They have various models for different cartridges. Your information will never be shared and you can unsubscribe with one click at anytime. 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. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative accelerationthe drag on the body is small in proportion to its mass. 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. Caliber means the diameter of the bullet, so a 50 caliber bullet is half an inch in diameter. This shows most dramatically in the case capacity where the .50 BMG can hold nearly 200 more grains of powder than the 338LM. 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. Beretta 3032 Tomcat [Review]: A Worthy Self-Defense Pistol? 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. G1 projectiles are flat based bullets such as spritzer bullets, where G7 projectiles are going to cover boattail spitzers. For comparison, a similar monolithic bullet in .50 BMG usually maxes out around 800 grains at 2,900 fps. The email address you entered is not valid. DARPA (Defense Advanced Research Projects Agency) contracted with Teledyne Scientific Company to develop the EXACTO program, including a .50-caliber guided bullet. And seeing the stopping power in action, we leave that to you. 50 caliber bullets can easily enter through a thick, concrete, or brick wall, a large tree, or even a person from a long distance. Recoil is also a component to accuracy though most will deny it has any effect on them. But a higher ballistic coefficient doesn't necessarily mean it is a better bullet. However, the strength depends on the sturdiness and power of the rifles used for this bullet. All data created using our free ballistic calculator. Customer Reviews. The 338 LM was designed and produced in the late 1980s. This American Eagle ammunition was produced by Lake City Arsenal to NATO specifications.
