Weapons have been used by man in one form or another from the very start. With advancement in technology, weapons have taken a modern shape. In recent times, there have been great strides made in making ammunition much more efficient that it has ever been.
Bullets remain the main form of ammunition even in an age of weapons of mass destruction due to their effectiveness and the ability to take out smaller targets. As the technology is advancing, so are the bullets. The two main types of bullets that are used are the Total Metal Jacket (TMJ) and Full Metal Jacket (FMJ).
Although any people think them as two different names for the same thing, these are actually different. The small yet significant differences that they have make a huge impact.
The jacket of a total metal jacket bullet is made from materials such as brass or copper. On the other hand, the jacket of the full metal jacket is made from metals such as steel alloy, copper-nickel or brass.
The TMJ is considered to be not as effective against a hard target and has a greater chance of fragmenting in such conditions in comparison with the FMJ.
The TMJ is less likely to be pressured in high velocities due to the thin plating when compared with an FMJ bullet.
The price of a TMJ bullet is greater than that of an FMJ bullet due to the overall performance and the type of metals that are used in its manufacture.
The TMJ is electro plated on to the core whereas the FMJ is drawn mechanically over the core of the bullet.
