Full Metal Jacket Bullet
A full metal jacket (or FMJ) is a bullet consisting of a soft core (usually made of lead) encased in a shell of harder metal, such as gilding metal, cupronickel or less commonly a steel alloy. This shell can extend around all of the bullet (alternatively termed a total metal jacket round) or, more often, just around the front and sides with the rear lead part left exposed. The jacket 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. The appearance of FMJ ammunition is highly distinctive when compared to hollow-point or soft point bullets. Historically, the first successful full metal jacket rifle bullets were invented by Lt. Col. Eduard Rubin of the Swiss Army in 1882. Full metal jacket bullets were first used as standard ammunition in 1886, for the French Mle 1886 Lebel rifle.

Famous quotes containing the words full, metal, jacket and/or bullet:
“Oh, it’s home again, and home again, America for me!
I want a ship that’s westward bound to plow the rolling sea,
To the blessed Land of Room Enough beyond the ocean bars,
Where the air is full of sunlight and the flag is full of stars.”
—Henry Van Dyke (1852–1933)
“There is a lot of talk now about metal detectors and gun control. Both are good things. But they are no more a solution than forks and spoons are a solution to world hunger.”
—Anna Quindlen (b. 1953)
“And what’s romance? Usually, a nice little tale where you have everything As You Like It, where rain never wets your jacket and gnats never bite your nose and it’s always daisy-time.”
—D.H. (David Herbert)
“Literary gentlemen, editors, and critics think that they know how to write, because they have studied grammar and rhetoric; but they are egregiously mistaken. The art of composition is as simple as the discharge of a bullet from a rifle, and its masterpieces imply an infinitely greater force behind them.”
—Henry David Thoreau (1817–1862)
