TMJ Ammo vs FMJ Ammo
Total metal jacket (TMJ) ammo and Full Metal Jacket (FMJ) ammo might have a thin difference. Some ammo fans are not even aware of the difference between the two. It is said that one can not be called a pure expert on weapons if one cannot differentiate these two.
TMJ
Total metal jacket is a design in which it covers the lead core of the bullet completely. It is basically made up of brass or copper and that it is usually used indoors to cut the lead content in the air. Originally this is created as a low-cost option to make a jacketed bullet. Most indoor shooting ranges, recommends that this type of bullets be used during practice.
FMJ
Full metal jacket is an ammo that has a casing formed around the base core. Other samples have a hollow opening with lead exposed in the core. It’s jacket is usually made up of solid material such as copper-nickel, brass or steel alloy. It is also noted that this is preferable to be used in gas operated weapons due to the lead deposits that it has.
Difference between TMJ and FMJ
Both are not made to expand on impact however, the difference lies on their penetration and the price range as well. Since TMJ is considered as plated bullets, it has been observed that its penetration with a hard target is not as efficient as using an FMJ since the plating is more fragile and will likely fragment more as compared with the full metal jacket. It is also believed that TMJ due to its thin plating, has a limited capacity to be pressured in high velocities, not to mention that it is more expensive than the full metal jacket type.
It has been debated that TMJ is safer as compared to FMJ as per airborne lead is concerned. Some says otherwise, but in terms of shooting, it will all boil down to the kind of activity that is being done, be it an actual operation or a just simply practicing.

In brief: TMJ is basically made up of brass or copper and that it is usually used indoors to cut the lead content in the air. FMJ’s jacket is usually made up of solid material such as copper-nickel, brass or steel alloy. It is also noted that this is preferable to be used in gas operated weapons due to lead deposits that it has. |
The English in this explanation is unnecessarily unpracticed and inexpert. How can a person depend on the expertness of the author?:
“Total metal jacket is a design in which it covers the lead core of the
bullet completely. It is basically made up of brass or copper…” Which is it, “covered lead,” or “brass or copper”?
“It is also noted that this is preferable to be used in gas operated weapons due to the lead deposits that it has.” The bullet has lead deposits (on it)?
” Some says otherwise…” Unpracticed English.
“TMJ is basically made up of brass or copper and that it is usually used indoors to cut the lead content in the air.” If TMJ is made up of brass or copper, then wouldn’t it eliminate lead in the air?
“FMJ’s jacket is usually made up of solid material such as copper-nickel, brass or steel alloy.” Then, if FMJ’s jacket is usually made up of solid material such as copper-nickel, brass or steel alloy, is FMJ’s jacket ever made up of liquid, gaseous material, or non-solid material?
Wow, aren’t you a douche. In order of your listing read:
1. Lead covered in brass or copper.
2. Yes, covered in brass or copper.
3 “The English in this explanation is unnecessarily unpracticed and inexpert. How can a person depend on the expertness of the author?”
..and your naziing on his “unpracticed” English?
4. The TOTAL METAL JACKET is made of brass or copper. (again, see 2.)
5. Less brittle. I think you know what he meant…unless your an engineer that needs everything spelled out for you because your imagination is dead.
I can’t believe no one else has called you out regarding the complete sackiness of your post. This guy was only helping out by offering his knowledge. Helped me…but I’m not dead inside.
