These rounds seem to have a hard time punching through window panes, heavy clothing, and sometimes even vegetation (which proved problematic in the jungles of Southeast Asia). What is M855? M855 is often called “green tip” ammo for its special color coding (the full metal jacket is painted green at the nose).

These .30-caliber (7.62 mm) full metal jacket bullets show the typical jacket openings exposing the lead alloy core on the base of the bullet to illustrate a full metal jacket may not completely enclose the core.

A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ('jacket') of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. Equest software for mac. A bullet jacket generally allows for higher muzzle velocities than bare lead without depositing significant amounts of metal in the bore. It also prevents damage to bores from steel or armor-piercing core materials. In military nomenclature, it is often labeled ball ammunition.
The bullet was invented in 1882 by Swiss Colonel Eduard Rubin while he was working for the Swiss Federal Ammunition Factory and Research Center, which developed ammunition for the Swiss military.[1][2][3][4]
The use of full metal jacketing in military ammunition came about in part because of the need for improved feeding characteristics in small arms that used internal mechanical manipulation of the cartridge in order to chamber rounds as opposed to externally hand-reloading single-shot firearms.[citation needed] The harder metal used in bullet jackets was less prone to deformation than softer exposed lead, which improved feeding. It is sometimes thought that military use of FMJ ammunition was the result of The Hague Convention of 1899, Declaration III, prohibiting the use in international warfare of bullets that easily expand or flatten in the body.[citation needed] However, jacketed bullets had been in use since at least 1882, over a decade prior to the Hague Convention.

What Is Hard Ball Ammunition
By design, fully jacketed projectiles have less capacity to expand after contact with the target than a hollow-point projectile. While this can be an advantage when engaging targets behind cover, it can also be a disadvantage as an FMJ bullet may pierce completely through a target, leading to less severe wounding, and possibly failing to disable the target. Furthermore, a projectile that goes completely through a target can cause unintentional, collateral damage downrange of the target.
