NATO adopted SS109 around 1980 as the standard 5. the fact that your measured ballistics data matched the calculated theoretical ballistic curve when the lowered value of BC was used is a strong argument in your favor. Steel core - These fall into two groups: Penetrators and Armor Piercing. Nov 18, 2015. Our Rubber panels are used in our bullet traps as replacement panels or mount to existing armor steel plate & significantly reduce any chance of bullet back splatter, ricochet & airborne lead. This is a newly manufactured, high-quality NATO-spec cartridge with a reloadable case. Manufactured at the Lake City Army Ammunition Plant to Federal Cartridge Company specifications for commercial ammunition. The difference in trajectory from bullet to bullet or barrel to barrel is usually less than the MOA thickness of the stadia lines. 300 Blackout CBJ. Ballistics Coefficient is the ratio of a bullets Sectional Density to its coefficient of form. In comparison with 7. 56 … bullet weighs the same but is longer, giving it a higher ballistics coefficient and the new propellant burns. M855 is the current load used by the US Military and is identified by green paint on its tip (M855 is often called “green tip”). 5 exhibits a superior ballistic coefficient and sectional density when compared to a 7. (Used in the M16A2/3/4 and M4-series weapons. resulting in a longer bullet that has better ballistic coefficient that regular lead/copper bullets and the. The velocity of the round can be anywhere from 3400-3800 (Highest I seen was with Carbon 55 Grain BTJHP). Well, the cartridges are virtually identical ballistically when bullets of similar weight are compared and both muzzle velocity and ballistic coefficient (BC) are factored in. Bullets are described by a ballistic coefficient , or BC, which combines the air resistance of the bullet shape (the drag coefficient ) and its sectional density (a. 1, an improved, lead-free variation of the Mod. When changing gears for long-range competition, it easily utilizes high ballistic coefficient, wind-bucking bullets weighing 68 and 69 grains and select 75-grain versions. 270 in various articles and forums on the internet.

But it is close enough for hunting under 250 yards. We have a huge collection of ammunition. military decided to adopt the 5. M855 and M193 aren't going to have the same ballistics out of the same gun. The ballistic coefficient of most of the under 75 gr bullets is fairly low (smaller number). 56 M855 round. Sold by the 420 round can, packed on 10 round stripper clips. Ballistic Coefficients are measures of objects’ abilities to overcome air resistance mid-flight. The M855 round, similar to the Army's M80 (7. Now, we can plug this figure into a ballistic calculator and see if our commenter is right. I a 16" carbine you're only losing about 100-125 fps and you'll still get a spin rate of 232,000 fps, allowing for good stability in anything other than sub zero temperatures. The US Army's Ballistic Research Laboratory measured a ballistic coefficient (G7 BC) of 0. Apparently it is superior to the standard M855 round when fired from an M4 or M16 rifle, increasing accuracy from 3–5 minutes of angle to 2 minute of angle. Ammo Deal: 240 Rounds PMC X-Tac M855 Green Tip, 5. The same round isn't going to have the same ballistics out of an M4 and an M16A4. Typically, the higher the number, the lower the drag of the projectile (low negative acceleration), and the better the bullet will cut through the air. Its ballistic coefficient is typically. Velocity is the key to explosive fragmentation. 56x45mm NATO 62gr M855 SS109 FMJ Penetrator 3100 FPS 150/Box Ammo #USA855L1W. 56mm have similar ballistic performances out to the 400-meter range. The difference is really negligible as shown by a ballistic calculator. I shot the 77-grain load into clear ballistic gelatin blocks from a distance of 10 yards. Cavity Back Bullets has two different 120 grain bullets with high ballistic coefficients (. Sectional density (SD) is the numerical result of a calculation that compares a bullet's weight to its diameter. Official qualification of the round consisted of a series of side-by-side tests with the current M855. For nearly every marksmanship discipline (including the aforementioned USMC Qualification course example) a shift of this magnitude would require a significant adjustment in elevation to. Too many variables such as bullet design, ballistic coefficient and even rifles will alter the outcome. Ballistic Simulations and Wind Tunnel Testing of 120 mm Mortar Bomb Tail Fin Geometries-In Search for Extra Range Tiainen, J. 308 Winchester / 7. 370 down to 0. 56 mm Minimi as the M249 SAW and the SS109 as the 62 gr FMJ M855 green-tip. Ballistic coefficient is typically measured with a 3 digit expression. With standard 55gr M855 ammo, the 50/200m rule is pretty close. And although it is intended for target shooting and other recreational fun, we don’t imagine for a moment that this ammo couldn’t save the day during a home defense situation. This ammo is regarded as the best M855 period. Even in short-barreled rifles, the SOST provides impressive ballistics — achieving 2925 fps in a 14″ barrel. They introduced the SS109 62gr steel core “penetrator” bullet that would eventually be used in our M855 round. While it is possible to achieve acceptable accuracy at 600 meters on a calm day, it is too risky on the windy days to really consider this round for military sniping purposes. Ballistic Coefficient: M855: Military designation for the 5. Go much past that even with match ammo (FGMM) and drift and drop/ranging become increasing issues. / Korhonen, M. 56x45mm in general.
