Jacketed hollow point.
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 .
The shell around a bullet, commonly referred to as the bullet jacket, is typically made of copper or a copper alloy. This metal jacket encases the lead core of the bullet, providing structural integrity, reducing barrel fouling, and improving aerodynamic performance. In some cases, bullets may have jackets made of other materials, such as brass or even polymer, depending on their intended use.
gilded metal jacket (GMJ) is basically the same as full metal jacket (FMJ) in that it provides a metal casing on a bullet core. The difference in the two metal jackets is the method of application. The full metal jacket (FMJ) is a casing that is applied to the core while the gilded metal jacket (GMJ) is plated directly on the core. For all intents and purposes, the GMJ rounds perform the same as FMJ rounds, but are less costly to manufacture, and therefore cost less to buy.
yes and no to make the bullet itself they use lead because it has a low melting point,it has some weight to it so when the bullet is fired the wind doesn't affect its accuracy and because lead is easy to mold and cool down. they use the copper as a coating to make fullmetal jacket rounds (fullmetal jacket is when the entire bullet is coated with copper even the bottom of it)
TMJ = Total Metal Jacket. <><><><> Typically a lead core, with a jacket of copper/nickel alloy that completely encases the lead core.
1. The FMJ bullet still has the base of the lead core exposed, a TMJ head is usually used in match shooting and has the lead core completely encased in copper. 2. The full jacket of the TMJ or Total Metal Jacket prevents separation of the lead core with the copper jacket, preventing the lead from blowing out. It is being used more and more as it also prevents much lead pollution as most of the lead expelled in the air by a firearm comes from vaporization of lead at the base of the bullet, which is covered by copper in the TMJ design. A shotgun, whose shot shell base is covered by a plastic or paper wad, produces the most lead in the air because of the great number of lead pellets abrading the barrel. A handgun or rifle shooting an exposed lead base bullet produces the next greatest amount of lead in the air. The TMJ design produces the least lead pollution.
Full Metal Jacket. The lead core is covered by a thin jacket of metal.
The mold cavity is made with the help of a pattern. so, in mold cavity we pour the molten metal, to get the casting now if we want a hollow cavity again in casting core comes to play.
.357 Magnum refers to the cartridge in that caliber. SOME of those cartridges are loaded with a full metal jacketed bullet- meaning that the lead core of the bullet is completely surrounded by jacketing metal- usually an alloy of copper and other metals.
Not very well if they have a lead core. Cupronickel is the jacket material and is not thick enough to hold up itself to much metal penetration. If the bullet has a steel core then the core would allow it to penetrate most steel plate depending on velocity of the bullet and thickness of the steel armor it was shot at. Even though the cupronickel bullet is somewhat shinny they are usually composed of approximately 75% copper. Currently there are no cupronickel bullets built to penetrate armor. Cupronickel bullets are old technology and were developed mostly by the Russians in about 1908.
The answer is Armor
the bar because it shoots a 30.6 and an ak47 shoots a 7.62x39 the bar has a bigger bullet the ak47 probbably has better penetration though because it often uses steel core full metal jacket ammo
