Is M80 Ball accurate?
John Peck Is M80 Ball accurate?
The U.S. military’s accuracy standard for M80 Ball (boxed or on stripper clips) is a mean average radius of 5 inches at 600 yards for all groups tested from a given lot of ammunition. That measurement loosely equates to a 10-inch circle or approximately 1.6 MOA at that distance.
Is M80 Ball boat tail?
This 7.62x51mm Ball M80 lead core, non magnetic, full metal jacket boat tail.
What is Ball M80 ammo?
The 7.62mm M80 Ball round is for use against personnel and unarmored targets. It has an unpainted bullet tip and is known by three other names: 7.62 x 51 mm, 7.62 NATO and . The round works in the M60 and M240 machine guns and a host of 7.62mm rifles, including the M24 sniper rifle and M110 sniper rifle.
Is M80 corrosive?
Winchester Ammunition, M80, 762NATO, 149 Gr., Full Metal Jacket, 20 Round Box. This ammunition is new production, non-corrosive, in reloadable brass cases.
How many grains are in a 7.62 round?
The 7.62×51mm NATO has 3.38 ml (52.0 grains) cartridge case capacity.
How important is ballistic coefficient?
In short, a high ballistic coefficient is indicative of a rounds ability to resist drag. BC is mostly used by rifle shooters. The higher the number, the less drag the projectile will experience. But a higher ballistic coefficient doesn’t necessarily mean it is a better bullet.
Does ballistic coefficient change with velocity?
Ballistic Coefficient (BC) values can, and usually do change in value with changes in velocity. Most bullets exhibit a lowering BC as velocity slows. The extent of how much a BC will change depends on each unique bullet shape.
Is .308 the same as 7.62 x51mm?
308 Winchester. 308 Win was specifically designed to be a civilian variant of the 7.62x51mm NATO, even hitting the market two years before the NATO adoption of the 7.62. Today, . 308 Win ammo is the most popular short-action, big-game hunting cartridge around, leaving its twin in the dust.
Is M80 ammo FMJ?
308 (7.62x51mm), FMJ, 147 Grain, 200 Rounds.
What grain is M80?
147 gr
Sniper and designated marksman rifles The standard M80 ball round weighs 147 gr and from a M14 rifle and M60 machine gun has a muzzle velocity 200 ft/s (61 m/s) faster than the M118LR 175 gr sniping round.
What is the form factor of a M80 ball?
It’s important to note that form factors are specific to their respective ballistic coefficients; we’ll see why in a minute. Let’s take an example. The 147gr bullet of 7.62mm M80 Ball has a ballistic coefficient of approximately 0.200 G7.
What is the ballistic coefficient (BC) value of a Hornady projectile?
Mach 2.0 (2,233 fps @ ICAO Standard Atmosphere) and Mach 1.75 (1,954 fps @ ICAO Standard Atmosphere) BC values are also available. As Hornady moves the industry to drag coefficient based trajectory calculations for these types of projectiles, the Ballistic Coefficient is becoming somewhat irrelevant.
Is M80 ball ammo any good?
Far from being relegated to belt-fed battle beasts chattering away in far off lands, commercial M80 Ball ammunition is relatively affordable, marginally available and capable of hitting targets with modest accuracy. That is about as good as we can expect in the current ammo market.
What is the ballistic coefficient (BC)?
Ballistic Coefficient (BC) values at Mach 2.25 (2512 fps @ ICAO Standard Atmosphere) should be used when comparing to other published BC values within the industry. Ballistic Coefficient values at Mach 1.75 (1954 fps @ ICAO Standard Atmosphere), should be used when calculating trajectories for shooting beyond 600 yds.
