The .25 caliber (6.4 mm) bullet on the left has a small cylindrical cavity in the nose, and the .35 caliber (9 mm) bullet on the right has a larger cavity holding an aerodynamic plastic tip. Green bullet, green ammunition or green ammo are nicknames for a United States Department of Defense program to eliminate the use of hazardous materials ...
Cartridge, Caliber 5.56 mm, Ball, M855 [Green tip]: 5.56×45mm 62-grain FN SS109-equivalent ball cartridge with a steel penetrator tip over a lead core in a full copper jacket. It is designed to penetrate lightly armored targets, such as body armor or light vehicles, and has a steel core that provides increased penetration.
Traditionally, these bullets are intended for use in rifles and single-shot handguns, as pistols are not normally used at the great distances where the streamlined ballistic tip is advantageous. However, a few companies produce pistol ammunition with plastic-tipped hollow points where the plastic is molded into a more rounded tip.
Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine.. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding.
This round is usually identified by a green over white paint tip mark. [3] Its tracer variant, which is typically only used with belt-fed machine guns in naval applications, includes a row of red paint between the green and white rows. The headstamp on the casing will not help to identify the round as Raufoss. Common headstamps are used, and ...

Cartridge, caliber 7.62mm, NATO, duplex, M198 (green tip): 7.62×51mm NATO duplex ball round with two 84-grain (5.4 g) bullets. The developmental designation was T314E3 . It was meant to increase the M14's volume of fire by doubling the number of bullets it could fire per minute.
In the case of the M196/M193 bullet set, the lethality differences are probably negligible for this reason. However, with the M856/M855 bullet set, the M855 ball round contains a steel penetrator tip that is not present in the M856 tracer bullet. As a result, different lethality effects can be expected against various targets.
