The M2 and M9 links, "pull-out" designs, are used in the Browning M2 and M3 machine guns. When dealing with more obscure cartridges that dont have a huge market and takes quite a lot more material to make and you have the trifecta for expensive rounds. Subject to political controversy due to the great power of the cartridge (it is the most powerful commonly available cartridge not considered a destructive device under the National Firearms Act), it remains popular among long-range shooters for its accuracy and external ballistics. Both of these cartridges have found a place in the long range shooting. Effect? It has a ballistic coefficient of .730. 50 BMG Ballistic Coefficient. Factory loads for civilian purchase are limited with most of the available rounds coming with bullet weights between 650 and 750gr. A.50 Caliber is a large bullet round with a 12.7mm diameter. With the .338 Lapua Magnum vs .50 BMG, recoil takes on a bit more of an important role. No extra bullets are sent. [4] A skilled sniper can effectively neutralize an infantry unit by eliminating several targets (soldiers or equipment) without revealing his precise location. So, it is evident that the bullet is dangerous and needs care while in use. . Hornady's original goal: "Ten bullets through one hole.". 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. and long-range bullets generally range from 0.5 all the way up to 1.0 with the .50 BMG! 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. .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 The time for a .50 calibre bullet to travel one mile at a constant speed of 1400feet per second is around four seconds. This bullet is 0.50 in diameter and typically 2.25-inch long. 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. In ballistics, the ballistic coefficient ( BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. According to the American Rifleman: "Actually, the Browning .50 originated in the Great War. Again, this conclusions and estimates are based solely on the factory loads we have been examining here and the data that accompany them. ", "How Will Illinois Law Banning Some Firearms Affect Gun Owners? The two most important variables are the Initial Velocity and the Ballistic Coefficient. Coming up on wounded animals, especially if they are predators, can be dangerous and being able to drop them cleanly takes this risk away. With its trajectory and energy and bullet design options there are no limits to the type of hunting you can do with it. Usually, a 50 cal round has a diameter of 12.7 mm diameter. For the .50BMG, we would recommend the Hornady A-MAX Match 750gr round. Looking at just the basic physics, a .50 bmg has a muzzle velocity of about 420 meters per second (1480 feet per second). That all said, there are deals out there. Ballistic Coefficient (BC) is basically a measure of how streamlined a bullet is; that is, how well it cuts through the air. In certain aspects and certain situations, sure, there are cartridges better suited to the task than others. 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. These ballistic coefficient values are said to be accurate to within about 5%. Other than armed forces, civilians use this bullet round for target shooting and sports. The .50 BMG is a bigger, heavier bullet that delivers a reliable killing shot up to an astounding range of about 3300 yards. .510 diameter. While there are parties who will place one cartridge over the other, we are not looking to do that in our comparisons. Check TopScopesfor Barrett.50 Cal. 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. Barrel Length inches 36 Ballistics Coefficient (G1) 0.707 Ballistics Coefficient (G7) 0.350 Sectional Density 0.362. Excellent quality, and great customer service from Dave Moore of Spider Firearms. Be aware you may consider some of them unusable. 300 yds. All in all, 50 BMG is the best cartridge with great ballistic coefficient, diameter, and other features that expanded its use. We will bring this up several times throughout our discussion but keep in the back of your mind that your ultimate choice should consider all of these results together rather than focusing on one independent category. For simply comparing two different cartridges, we are going to omit it for the sake of clarity. [14], Some civilians use .50 caliber rifles for long-range target shooting: the US-based Fifty Caliber Shooters Association holds .50 BMG shooting matches. In our minds, there is no one cartridge that is above and beyond better than another. What is the best scope for a .50 BMG and what is the strongest 50 BMG? [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. As for powder charges, we used conservative numbers for each round based on the hand loading specifications from Nosler. Velocity fps: 2940: 2806: 2677: 2551: 2428: 2309: Energy ft lbs: 12666: 11541: 10499: 9534: As the 50 BMG bullet has a high ballistic coefficient, it is used for powerful sniper rifles. 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. This is useful to get a legalized firearm with licenses. More importantly, we are interested in how flat a bullet flies over a given distance. Fill, sign and download Ballistic Chart online on Handypdf.com Seriously, these are heavy duty rounds that fill a very specific niche in the shooting world. Again, these numbers can vary based on the variables, but with our consistency, we think the comparisons are more than valid. The primer type specified for this ammunition is Boxer primer that has a single centralized ignition point (US and NATO countries). If you do not have a Shooting Chronograph, I strongly suggest you purchase one. Well, for 50 BMG, you're looking at $11-$16/round for military surplus ammo. This data was taken from the standards used by the ballistic calculator for the .338 LM and the .50 BMG rounds. 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. [42] Maryland imposes additional regulations on the sale and transfer of .50 BMG rifles and other "regulated firearms", and limits purchases of any firearm within this class to one per month, but does not impose registration requirements or any form of categorical ban.[37]. Unsubscribe at any time. There are several variants of this 50 caliber round. In addition, these snipers will have less drift from the winds of the bullet. How important the ballistic coefficient is with shooters often depends on the distance of shots they are taking. During operation or simply game shootings, it can make a significant wound in cases of accidents. They do have some pull marks. 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.. .338 Lapua Mag vs .50 BMG Cartridge Comparison. Your information will never be shared and you can unsubscribe with one click at anytime. No spam. Stringent quality control ensures proper bullet seating, consistent charges and pressures, optimal velocity, consistent overall length and repeatable accuracy. This comparison is interesting because of how similar the sectional densities are despite the major differences in bullets. Put me on the Waiting List. 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. kilojoules). There is no doubt that both are designed exclusively for successful performances in the field. Higher velocities, with a stable bullet, also aid in long range performance, which is critical for both hunting and competition shooting. As you notice, the .50 BMG has nearly double the recoil energy than the .338 LM. 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 ). A custom-made 12/70 slug shell with a shortened .50 BMG tracer bullet for 12 gauge shotguns. The cartridge itself has been made in many variants from armor piercing to tracer rounds, though most factory loads that can be accessed by civilians are the typical bullets. Under STANAG 4383, it is a standard service cartridge for NATO forces as well as many non-NATO countries. Obviously, this would be an advantage for shooting round out at 1,000 yards or more. 50 BMG has a 12.7mm diameter and is also used in snipers and machine guns. In addition, these snipers will have less drift from the winds of the bullet. The majority of its use in these circles is through extreme distance shooting though there are small circles that utilize it for hunting purposes, mostly for large or dangerous game at extreme distances. [9] The former record for a confirmed long-distance kill was set by U.S. Marine sniper Carlos Hathcock in 1967 during the Vietnam War, at a distance of 2,090 meters (2,290yd; 1.30mi);[10] Hathcock used the .50 BMG in an M2 Machine Gun equipped with a telescopic sight. Sometimes, the wound may be fragile, but it may also get fatal. Huge bullets with enough powder to send them downrange at supersonic speeds are going to produce enough kick to knock you down. Some of them can also be semi auto-loading guns. 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. However, sectional density, the relationship between . Its ballistic coefficient is 1.050. The auctioneer claims that it is only one of twelve built and the only other known example resides at the Ford Benning sniper school. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. They can easily enter through light armors and hit targets. This large amount of force is very destructive to surrounding tissue and organs. Even after the differences between 50 Cal vs 50 BMG, we see that they are quite similar in various features. Basically, BC is a measure of how . It can shoot up to ranges of 330 yards and floats in the air for about seven seconds, before dropping to the ground. Similar to snipers, 50 BMG pistols are also made of hard materials to support the powerful cartridge. [15], A common method for understanding the actual power of a cartridge is comparison of muzzle energies. 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. Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 BMG can exceed this normal BC. As we mentioned earlier, the velocity has a lot of influence on other aspects of the bullets behavior such as expansion. 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. While it is only two factors that go into stopping power, they are the best for comparing two cartridges besides comparison in the field. 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. 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. You would be surprised how many of them have never given their rounds BC a thought. The common rifling twist rate for this cartridge is 1 in 15in (380mm), with eight lands and grooves. 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).
