Topic: FMJ bullet


In the News (Tue 2 Dec 08)

  
  Full metal jacket bullet
A Full Metal Jacket bullet (or FMJ) is a bullet that is encased in a copper-coated steel or gilding metal jacket, designed to stop the bullet from fragmenting within its target.
FMJ ammunition was introduced for ostensibly humanitarian reasons, as the Geneva Conventions prohibit the use of expanding or fragmenting bullets in warfare.
Furthermore, because the bullet does not expand, FMJ bullets are much more effective at armor-piercing[?] than hollow point bullets.

 Full metal jacket bullet - Wikipedia, the free encyclopedia
An example of FMJ bullets in their usual shapes: pointy ("spitzer") for the rifle and round for the pistol.
A full metal jacket bullet (or FMJ) is a bullet encased in a copper alloy such as gilding metal, cupronickel, or a steel alloy shell.
The bullet relies on its victim to desanguinate, whereas soft-tipped and hollow point bullets are designed to shock the system, destroy vital organs, and to speed the desanguination process.

 SELF DEFENSE FORUMS: For A Fighting Chance
As long as the bullet has enough velocity to completely penetrate, it wouldn't matter if it was a 9mm bullet going 800fps or 1200fps, it would create the same wound (again, assuming no expansion because it's an FMJ bullet).
Unless a bullet is able to impart enough energy to cause significant hydrostatic shock (causing the tissue to stretch beyond it's elastic capability and tear), then the wounding effect is basically just how much meat and/or bone the bullet (expanded or not) is able to push through, cut through, and otherwise disrupt.
FMJ 9mm bullets, there may be a difference in impact shock if the bullet hits bone and creates secondary projectiles.

The flow type at the bullet's surface changes from a laminar boundary layer at the forward region of the bullet, which is characterized by parallel stream lines, into a turbulent flow, beginning at the cannelure.
For a 9 mm Luger FMJ pistol bullet, moving slightly faster than the speed of sound (see figure) one finds the following significant differences: the Mach cone is still present but no longer attached to the bullet' s tip, and the opening angle of this cone has increased.
Finally, for a cal..32 ACP pistol bullet, moving at a speed considerably below the speed of sound (see figure), all shock waves are absent, and what remains are the turbulences behind the bullet's base.

Bullets of this type will typically end their movement through the target in a tail-first aspect.
It is possible for a bullet to enter the body and not tumble, or to tumble and not fragment, or to suffer delayed fragmentation.
Second, FMJ rifle bullets all inherently have armor penetrating capability while retaining extremely high tissue disruption abilities, while a hollowpoint bullet will still have the lack of armor penetration values that is almost universally attributed to hollowpoint designs.

 Gunboards - soft point ammo shoot left
One cannot expect a rifle that is sighted in for one brand and type of bullet to print in the same place with a different brand or type of bullet.
Differences in bullet design, ballistic coefficient and powder charge are all variables that differ between loads and cause these variations.
The heavier bullet would generate a more forcefull recoil impulse, and the barrel would tend to move further upward than when firing the lighter bullet.

Bullet weight for the 9 is 124 grains (it’s possible that a 135 grain may be released in the near future).
If the bullet strikes plywood it digs in and expands, but as is the case with a soft point or hollow point, if the angle of impact is great enough, it will depart at the approximate angle of incidence.

 The Great Bullet Debate
If the bullet has enough momentum to slam the person being shot up against the wall or flat on their back then the person shooting the gun would experience the same momentum in the reverse direction.
This effect is closely related to bullet momentum (actually it's roughly proportional to the bullet weight times the velocity to the 0.6 power).
A FMJ bullet has a front end that basically doesn't speed up the flesh as much as a flat nosed or an expanded HP bullet does.

 The Beltway Sniper Case2
This makes the firearm examiner's work particularly difficult when he or she searches for areas on the fragments that might have identifying striations which can be used to identify the actual firearm used.
Because of the difficulty inherent in working with deformed fragments, it is likely that the bullet evidence in some of the shooting incidents will not be sufficient to identify to any firearm.
There is a dynamic which occurs with many.223 bullet types: After going through a few inches of soft tissue, the bullet will yaw (turn sideways instead of point-forward.

 FRANGIBLE AND NONTOXIC AMMUNITION
While this action does lower lead levels to some extent, the FMJ bullet still injects some vaporized lead into the air due to their exposed base.
Furthermore, as opposed to lead-free bullets in which the projectile is made of solid copper or some other metal or ceramic, Longbow’s frangible bullet made of a polymer-copper compound, completely eliminates ricochet and splash back.
Bullet weights and velocities are balanced to yield recoil and point of impact with a minimum variation from duty ammunition.

 Why are hollowpoints so accurate? - Topic Powered by eve community
If a bullet tip is not dead center the air pushing on one side or another of the bullet when spinning would create a vacuum (like a curve ball) but on a much smaller scale.
Indeed, a traditional ball FMJ bullet could theoretically be made to shoot as well, if the base could be formed as consistently, and thus obturate & exit the muzzle exactly the same way for each shot.
BTW, the much-promoted boat-tail bullet generally offers no real ballistic advantage within the first 500 yards or more, and such bullets are harder to make to equal accuracy compared to flat-base versions because the base profile must be perfectly concentric at multiple planes.

 Introduction to collecting the 9mm Parabellum (Luger) Cartridge
These were replaced in Germany with 124grain FMJ bullets with a round ogive in 1915-1916 (Figure 3) though truncated cone bullets were used on commercial loads in the United States into the 1930s.
This bullet was initially identified by the fl bullet jacket, but in 1944, it became the standard German ball load and the flened bullet jacket was dropped.
Similar heavy bullet loads for use with silencers were produced by the British after World War II with bullet weights up to 170gr and are often identified by various color dots on the case head.

The downside of the Speer bullet is the less sensitive "Cleanfire primer" which may not provide reliable cartridge ignition in guns that have had trigger work, a lighter mainspring installed, or bobbed hammer.
This is not a condemnation of the Gold Dot bullet, all expanding.25 ACP bullets exhibit inadequate penetration.
Although the aerodynamic design of the semi-pointed FMJ bullet does not wound as efficiently as an expanding bullet, an FMJ bullet will at least penetrate deeply enough to reliably reach, and crush a hole in, vital tissues from any shooting engagement angle.

 Bullet Swaging in a Nut Shell
Most open tip, flat base bullets can be made with the CSP-1 press and the FJFB-3-S 3-die set, a bottle of swage lube (CSL-2), a bag of jackets (or a jacket making kit), a roll of lead wire (or a core mould), and a core cutter (if you use lead wire).
There are specific techniques required to swage solid rod into bullets (you cannot use exactly the same processes and tools as for soft lead and/or jacketed bullets with solid materials, as the pressures skyrocket beyond 100,000 psi unless certain techniques are used).
The WEIGHT of the bullet isn't terribly important to the die you choose, since all the dies make a wide range of weights simply by adjustment of the punch holder.
