Full metal jacket bullets have an outer shell made from one metal, with a softer interior core manufactured from another—the latter typically being lead. FMJ is the firearm industry’s shorthand for the design, although some militaries and enthusiasts refer to it as “ball.”
FMJ loads are full metal jacket ammo and are most commonly used by shooters for range training or during competitions that require high-volume shooting. These rounds are not designed to expand on impact with a soft target, making them a poor choice for self-defense or hunting in most scenarios.
FMJ Bullet Design
Lead was ideal for the spherical projectiles in early firearms, thanks to its relatively low melting point, abundance and energy-carrying mass. As gun designs improved—bringing with them higher muzzle velocities, increased chamber pressures and a departure from single shots. The malleable metal’s drawbacks in bullets also became obvious. It fouled barrels, deformed with eerie regularity on exit and even made chambering a second round from newfangled magazines a hit-and-miss affair.
Swiss Col. Eduard Rubin discovered a solution in 1882 when the mechanical engineer tested a bullet with its lead core enveloped in copper—the first FMJ. His experiments determined the tougher and higher-in-melting-point exterior minimized fouling and, thanks to copper’s reduced willingness to bend unpredictably, improved cycling of fresh rounds into a firearm. In addition, the layer of slightly lighter material had little impact on the bullet’s ability to retain energy downrange and the projectiles were not deforming.
Modern FMJ Manufacturing

Modern manufacturing of an FMJ begins by shaping the material that will become the jacket into a uniform cup. Companies typically use copper although they continue to discover and harness a variety of advantages offered by other alloys.
Core material—usually swaged lead wire—then goes into the cup and pressure applied to draw the jacket over it. This removes issues like air pockets or other performance-robbing inconsistencies at the same time. Lead lends itself extremely well to the process due to its ductility.

FMJ Advantages
FMJs are inexpensive, a fact reflected in the price of factory ammo loaded with the bullet design. That makes them ideal for high-volume shooters, competitors and plinkers.
They may be budget-friendly, but don’t underestimate their long-distance performance. Even after you’ve learned to adjust for the wind at 1,000 meters, most FMJs outperform the shooter. When you’re ready to dial things up feel free to invest in loads with fine-tuned projectiles, but it’s surprising how this routine firing line fodder is the preferred choice at major training academies.
Cleanup is a breeze, too. If you’re not fond of scrubbing bits of lead from the hidden recesses of your barrel, you’ll appreciate FMJs. Thousands of gun owners owe thanks to Col. Rubin—few know his name, although most appreciate his ingenuity.
Annoying stovepipes and many other “jams” can disappear, too. With lead’s tendency to bend, dig and otherwise defy the purpose of a magazine’s feed lips blanketed in copper, things get more reliable.
Ball Round Ammo
FMJs are also better at containing lead when they hit a target. The metal’s dust/vapor is a major concern at some ranges, particularly indoor facilities. This style bullet is mandatory at some facilities, a rule that supplements the cutting-edge ventilation systems always in use.
FMJ Disadvantages
FMJ bullets are notorious for an unwillingness to expand at bullet impact. Terminal ballistics that make this style of bullet style not recommended for self-defense or hunting. They often pass completely through the target, whether it’s a deer or felonious attacker, delivering minimal stopping power. With little loss of kinetic energy, they can keep going through most metal, walls or untargeted animals in the herd until friction and gravity finally grind things to a halt.

There are better bullet designs for those who hunt, carry or are ready to defend their family and home. They’re tailored to maximize energy delivered on the target to ethically take an animal or stop the assault, a task the FMJ doesn’t perform well. The design of the jacketed hollow point or JHP as it is commonly referred to is a much better choice for hunting or self-defense situations.
Plated vs FMJ
A plated bullet is related to the FMJ, visually anyway. The resemblance is there, but the two are not identical. It also has an exterior metal shell, but the manufacturing process explains subtle differences.
To create a plated bullet, manufacturers submerge the core in a solution rich in “jacket” material. The exterior coating collects after the introduction of an electrical charge, an electrochemical technique more often associated with the jewelry industry. The process results in complete coverage, including the base of a plated bullet. Manufacturers stuff the end of the bullet inside a loaded cartridge, so the average shooter who doesn’t reload will never notice.
CMJ vs FMJ
Whether or not these coated metal jackets (CMJs) quite live up to the FMJ family’s fame is a matter of discussion. Those with opinions on the subject often point out some of the finer differences between the two. A plated bullet’s “jacket” material, for example, has not gone through the heavy machining process a pureblooded FMJ undergoes. Without that work-hardening, the former is theoretically more prone to nicks and bends. Those imperfections tend to hang up when traveling from a gun’s magazine into the chamber.
Other often-cited factors include a typically higher price tag, a fact that reflects thicker coatings require a longer stay in the solution. Performance, particularly at long range, can also be a concern. The slightest change in a bullet’s weight distribution—even if it weighs the same—can affect the point of impact. Shooters typically only notice the change when firing at great distances.
FMJ-BT Ammo
There are many forces affecting a bullet as it travels downrange. Minimizing their impact increases accuracy, the primary reason long-distance shooters favor boat tail (BT) bullets. Many hunters, competitors, LEO and military marksmen prefer the boat tail bullet design for its precision accuracy.
What Is Ball Rifle Ammo
The design is simple and is visible at a bullet’s base. The sides of boat tail bullet end with a slight taper instead of the more traditional and abrupt 90-degree angle. The best way to visualize the concept is to think of a boat hull from an overhead view. The gentle inward bend at the stern is the BT design, hence the name. It reduces turbulence—even friction—as air passes over and behind a projectile during flight. That makes an FMJ-BT the best choice for anyone shooting at extreme range.
FMJ Ammo Legacy
Although the basic concept of the FMJ remains the same, advances in technology have fine-tuned the design to levels unimaginable by Col. Rubin and his development team at the Swiss Federal Ammunition Factory and Research Center—then considered among the world’s foremost in ballistics research. There’s no doubt they’d marvel at the modern material and manufacturing but appreciate the fact it all remains true to the primary goal, one they accomplished more than 100 years ago.
Most shooters tend to think of the firearm as being responsible for the accurate placement of bullets downrange, and there’s nothing wrong with that because it’s absolutely true. However, that’s not the whole truth. What we sometimes ignore, or perhaps just don’t acknowledge quite as often, is the critical role played by the ammunition. Poor quality ammunition is going to result in sub-par performance from any firearm, so when you want the absolute best accuracy from your rifles or handguns then you’re going to want to buy what’s called match ammo.
In short, match ammo is ammunition that is designed to be more consistent and therefore more accurate than general-use ammunition. While the origin of the term “match” with regard to ammunition is a bit fuzzy, it’s a safe bet to say that it came about as a way to identify especially consistent ammunition that would be suitable for use in formal shooting matches or competitions. This is still a pretty broad term though, since different shooting disciplines require different bullet performance.
For example, match rifle ammunition will often utilize specialized bullet design features such as a boat tail and an open tip. These help the bullet retain velocity better by reducing aerodynamic drag. Meanwhile, some types of match pistol ammunition will use wadcutter bullets that make cleaner holes in paper so that target scoring is easier.
How It’s Made
One vitally important thing to understand about match ammunition is that there is no universal standard that ammunition must meet for it to be labeled “match”. So how is match ammo made then? Is it uniquely designed from the ground up? Is it simply loaded with a match-type bullet? Is it merely especially accurate cartridges made from the same machines as all the other ammo? Well, it turns out the answer is all of the above.
CCI, who makes primarily .22lr ammunition, simply tests their normal standard velocity rounds for unusually good accuracy. Their ammo expert informed me that once a group of especially accurate rounds has been identified, it is isolated and tested again. If enough of these cartridges pass the accuracy requirement they are then packaged as Green Tag or Automatch ammunition according to CCI’s testing criteria.
When I contacted Magtech Ammunition to find out what made their match ammunition different from their standard ammo they told me, “The difference in our match ammunition is the projectiles… brass forming and primer seating are completed on our standard equipment.” Conversely, Federal Ammunition informed me that the only thing their .308 match ammunition shared with other Federal .308 loads was the casing. The primer, powder, and of course the Sierra Matchking projectile were specialized for enhanced accuracy.
So while each company has a method to set apart their standard ammo from their match ammo, the criteria differ from one company to the next. It’s also important to keep in mind that we don’t have the exact quality control procedures or accuracy specs for any of the major ammo companies. Without that information, we can’t reliably compare one company’s standards to the next. For example, Magtech may very well be holding their standard ammo to higher specifications than Federal, and thus not require specialized primers or powders to get great match loads. The only way to know for sure what a given match load is capable of is to try it out at the range.
So just how much better does match ammo shoot?
At this point I was determined to get some definitive and quantifiable build-spec and performance differences between standard and match ammo. To this end I began digging into official U.S. military design specifications for the 7.62 NATO rounds, particularly the M80 standard FMJ round and the M118 Match round. While actual design drawings and material specs eluded me I was able to determine that each round utilizes different casings, primers, and propellants. This basically means that military match ammo is designed from the ground up instead of being a modification of an existing load or just cherry-picked cartridges.
So just how much more accurate are match rounds compared to their standard counterparts? According to military specifications the standard FMJ rounds had to produce and average group size of no more than 15” at 600 yards over multiple targets. The Match grade rounds had to produce average group sizes of no more than 7” at the same range. In terms of MOA accuracy the standard FMJ was required to shoot 2.39 MOA and the match ammo just 1.11 MOA.
Granted, these are only the minimum accuracy standards and I can say from experience that the M118 round will greatly exceed those criteria, but it does provide a baseline for just how much more accurate match ammunition can be than standard ammo. It’s pretty cool to think that your rifle may actually be twice as accurate as you thought, isn’t it?

What Is Hard Ball Ammo Made
Because of the lack of industry-wide standardization it’s very common for various brands of match ammunition to perform differently depending on the gun used to fire them, so it’s best to test a variety of match loads to find out what works best in your particular firearm. It’s also good practice to buy ammunition from the same lot number whenever possible in order to avoid any cartridge inconsistencies caused by machine wear or recalibration during the manufacturing process. The lot number can usually be found on the exterior of the box or case that the ammunition shipped in.
