Does FMJ increase damage against people?
To put things simply, while FMJ does work in Warzone, it is unlikely to be a perk that many players will want. That is because FMJ does not increase damage against enemy players, and it does not improve a weapon's abilities against armor, as that is not considered equipment.
A Full Metal Jacket (FMJ) is a bullet that has a soft core, usually with lead, and is encased in a harder alloy metal such as cupronickel or gilding metal. The purpose of these rounds is to hold their trajectory, and they have greater penetration against soft tissue.
As regards destruction pattern, the radiological analysis reveals that a single shot fired with a full metal jacket bullets causes destruction along the bullet path that includes the dislocation of individual fragments and the formation of fractures radially from the bullet path.
Call of Duty: Black Ops II
It does not increase damage in multiplayer. FMJ cannot be used in conjunction with the Millimeter Scanner.
Exit wounds from a FMJ (left) vs a hollow point (right). You can see that the hollow points deal considerably more damage. You can see that the exit wound on the hollow point is significantly bigger. That's because hollow point ammo mushrooms and fragments when it impacts a target.
If you're going to load FMJ ammunition in your carry firearm, you need to have perfect target isolation and know what's going on beyond your target. Unless you're required to use FMJ by law, Michalowski does not recommend it for self-defense.
Hollow point bullets are the most common type of round used by American police.
If you are shooting 9mm full metal jacket ammo also referred to as Ball ammo, overpenetration is a very serious concern in civilian and police shootings. In short yes 9mm ball will often go completely through a person.
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.

FMJ is a weapon perk that increases bullet penetration and damage against enemy killstreaks. Killstreaks can be incredibly powerful in Call of Duty: Modern Warfare, so it is common for players to equip an LMG with FMJ to counter them without having to fill a weapon slot with a launcher.

A hollow-point bullet is a type of expanding bullet which expands on impact, causing a more lethal hit without penetrating further than necessary.
But what does this have to do with hollow points? Well, it's simple. Since a hollow-point bullet expands when it enters soft tissue, it creates a larger wound channel inside the target, increasing the chances that incapacitating damage will be done.
FMJ bullets are incredibly strong and have greater penetration capacity and less expansion in soft tissue. But there is a big pros of FMJ that these bullets do not expand upon hitting their target that makes them ideal for target shooting.
Jacketed Hollow Point Bullets
In addition to expansion, some hollow points are also designed to fragment, causing multiple wound channels and even greater physical harm. Jacketed hollow points are considerably more lethal than regular bullet ammunition.
Will FMJ penetrate body armor? No it won't anymore than a hollowpoint won't. The two most important factors assuming standard material & not armor piercing is diameter of the bullet & velocity. So a 9mn fmj vs hollowpoint will both flatten out about the same on most Level IIA, II & IIIA soft body armors.
223/5.56 rounds, . 308, 7.62 x 39mm and even . 300 Blackout are all equally damage-inducing depending on application. The reality of the situation is that for modern uses, there is no one round that does more damage in all situations for all shooters.
Yes the rounds can for sure go through walls.
Full metal jacket (FMJ) bullets are a cheap option for plinking at the range but rarely, if ever, should be used for hunting purposes. FMJ projectiles are not designed to expand and so subsequently punch straight through the intended target.
Does FMJ increase damage through walls?
The FMJ perk will increase your damage through cover, so if someone is behind a wall or hiding behind a different structure, the FMJ perk will help in this case, but not in an open battlefield with no objects in the way.
FMJ rounds are normally used for target practice and plinking because they are cheaper than JHP. Furthermore, they are more streamlined and designed to continue through their target with minimal deflection or deformation of the bullet. This makes FMJ bullets more ideal for barrier penetration than HP bullets.
Does the military use FMJ or hollow point? For absolute sure, full metal jacket rounds. Any round not fully jacketed or designed to flatten or fragment on impact with the human body is currently forbidden for use in warfare according to guidelines of the Hague Convention for all nations abiding by it.
In the end, titanium is bulletproof for the most part against bullets fired from guns that one would likely find on the shooting range, on the street or on the hunt in the mountains.
Usually FMJ bullets are copper clad with a lead core. They can penetrate metal or body armor not rated to stop them but their purpose isnt AP unless it is designed with a penetrator core.
