Who is PMC?
PMC X-Tac 5.56mm 55 Grain FMJ Ammo is an outstanding product of Poongsan Corporation, a South Korean company with a rich history in the ammunition industry. Having profound expertise in non-ferrous metals, the corporation bought out South Korea’s ammunition plant in 1973 and has been producing ammo of all stripes ever since. The factory bears the name ‘Precision Made Cartridges’, hence the PMC as the name of the brand.
The initial goal was to meet all the needs of the South Korean military to break its dependency on foreign importers. Long story short, the company accomplished that task with flying colors and even managed to spread its influence beyond the country’s borders. As of 2024, PMC ammo is used by numerous law enforcement agencies and militaries all over the world. If there is any better proof of the brand’s quality than the trust of the people who deal with firearms every day, the chances are PMC has that proof in their basket.
The Basics of PMC X-Tac Ammo
Now, the full name of this magnificent round is PMC X-Tac 5.56mm NATO 55 Grain FMJ. Some might see nothing but a collection of random words, but every letter and number stands for an important aspect of the round.
X-Tac is the name of the ammo series. PMC has many series in their portfolio, and this one is reserved for law enforcement and military applications. This series in particular is in service with the South Korean military and some of the NATO countries’ armies, as it meets the set specifications.
5.56 NATO is the caliber and another confirmation that the ammo complies with the Alliance’s standards. The caliber is often seen on popular AR-style rifles and carbines, which are known to be one of the most popular gun choices for American gun firearm owners. The round has passed the test of time and apparently is the one you’re interested in.
55 Grain is the weight of the bullet, and it’s one of the two load variants for PMC X-Tac 5.56 ammo. The bullet weight is not the only feature that differentiates these two loads, but it is the most easily noticeable one.
FMJ stands for Full Metal Jacket, and that’s the style of bullet – the nose and the sides covered with harder metal. You can expect this round to boast great penetration and be pretty affordable and clean to shoot. But don’t expect it to inflict as much damage as JHP or give the match-grade precision.
Features of PMC X-Tac 5.56mm 55 Grain FMJ Ammo
An experienced shooter needs but a glance to understand everything I’ve written in the section above. But you never know who may come across your writing, and I’d rather readers had an understanding regardless of their experience. But it’s time to get to features that the name of the ammo won’t give away.
Let’s begin with the round’s general quality. Poongsan Corporation’s expertise in metalwork truly shows – the exterior looks quite well-made. The primer is sealed, which boosts the reliability of the round and makes it highly weather-resistant. Rest assured, no weather, however adverse, will undermine the performance of this round. The annealed brass case is another high-quality element of the round’s exterior that also happens to make the ammo great for reloading. I prefer my ammo preassembled, but if you are a reloading enthusiast, this ammo will definitely bring a smile to your face.
Appearances aside, let’s look at more functional features like bullet design. The name doesn’t have it, but the bullet is boat-tailed. Unlike traditional bullets with their flat bases, the boat tail bullet is tapered toward the base, its sides narrowing slightly to resemble a boat. The purpose behind this design is to make the flight of the bullet steadier by increasing the bullet’s stability. It will be less affected by the wind and thus will have a better ballistic coefficient.
Field Test: PMC X-Tac 5.56mm 55 Grain FMJ
The words don’t mean much unless they are backed up by performance. So, how does PMC X-Tac 5.56mm 55-grain ammo shoot? I’ll start by saying that not a single round failed. FMJ ammo is generally known to be more reliable than other types, but it’s always nice to know you can rely on a round.
I had 10 boxes to test, which is 200 rounds, which is more than I’ve tested at one go so far, so this selection is pretty reliable. As a reminder, I tested these with a Daniel Defense DDM4 V7, 16” barrel.
