The steel-tip penetrator of the M855A1 is noticeably separated from the jacket of the bullet and can spin, but this is part of the design and does not affect performance. The M855A1 costs only 5 cents more per round than the M855. [140] The M855A1 bullet has a 1 ⁄ 8 in (3.2 mm) greater length than the SS109/M855. [141]
Its light recoil, high-velocity and flat trajectory allow shooters to take headshots out to 300 meters. [127] Newer M16s use the newer M855 cartridge increasing their effective range to 600 meters. [23] They are more accurate than their predecessors and are capable of shooting 1–3-inch groups at 100 yards.
The longer, less dense M855A1 bullet must be seated deeper than the lead core bullet it replaced to maintain the same exterior cartridge dimensions required for reliable functioning in self-loading firearms; and higher pressure is required to obtain the same bullet velocity with reduced propellant volume. Increased pressure causes gas port ...

The standard M80 ball round weighs 147 gr and from an M14 rifle and M60 machine gun has a muzzle velocity 200 ft/s (61 m/s) faster than the M118LR 175 gr sniping round. However, the M80 drops to subsonic velocity around 900 m (984 yd), while the initially slower M118LR is supersonic out to 1,000 m (1,094 yd) due to its low-drag bullet. [12]

Siacci found that within a low-velocity restricted zone, projectiles of similar shape, and velocity in the same air density behave similarly; or . Siacci used the variable for ballistic coefficient. Meaning, air density is the generally the same for flat-fire trajectories, thus sectional density is equal to the ballistic coefficient and air ...
