In my experience, PMC X-TAC is great for target practice. I buy it in bulk to ensure I’ve always got plenty of rounds on hand for a rainy day.

But is X-TAC ammo good for your AR-15 carbine? Or should you go with a more traditional brand like Winchester, Remington, or Lake City? In this PMC X-TAC 5.56 ammo review, we’ll take a look at what this ammo has to offer and why you shouldn’t hesitate to order some PMC X-TAC ammo for your stockpile.

PMC X-TAC 5.56 Ammo Overview

In 1973, the Poongsan Corporation founded the nation of South Korea’s first defense industry facility: Angang Ammunition Plant. Poongsan would go on to establish the Precision Made Cartridges (PMC) brand in 1982 as part of its effort to export ammunition to overseas commercial markets.

PMC utilizes what is known as vertical integration, meaning that it controls every aspect of its ammo’s production cycle. From primers to brass cases to all the different types of bullets loaded in their ammo, PMC maintains strict quality control standards to ensure every cartridge that leaves its factory will work as intended.

This doesn't merely ensure that PMC ammunition is high-quality. It allows PMC to keep its costs low by avoiding paying middlemen for ammo components. Furthermore, if supply chain issues ever crop up, PMC would be able to restart its production faster than companies that must wait on order fulfillment from third parties.

PMC X-TAC is the same ammo used by the South Korean military and its NATO allies. It’s legit Mil-Spec ammo, just like you would expect to receive from our own government’s Lake City Army Ammunition Plant.

Loaded with standard 55 grain FMJ or 62 grain LAP (“light armor piercing,” which is the same as an M855 “penetrator” minus the green paint) bullets, PMC X-TAC 5.56 ammo adheres to NATO specs and comes with sealed primer pockets and annealed brass cases. This makes them resistant to moisture infiltration and reloadable, respectively.

If you want to buy in bulk but hate owning tons of ammo cans, PMC X-TAC can be purchased in hermetically sealed battle packs. These are perfect for throwing in the back of your ammo closet to save for a rainy day.

To summarize: If you’re looking for good PMC 5.56 ammo to load into your favorite rifle or carbine, don’t hesitate to try out a few boxes of X-TAC 5.56 PMC ammo. It won’t let you down.

Our PMC X-TAC 5.56 Ammo Review

I purchased my first AR-15 in 2008. And after field stripping my new rifle a few times to get more familiar with it, I was on the hunt for some ammo to feed it. My first trip to the range included multiple boxes of rifle ammunition from various manufacturers like Winchester, Remington, and PMC Bronze because I needed to know what my new baby liked.

The PMC ammunition functioned flawlessly, and I was very impressed. However, I knew I wanted something a little closer to NATO ammo to stockpile, just in case.

Enter PMC X-TAC. After my first trip to the range with it, I was hooked.

This PMC ammo does everything I could ask for from a military-style round. It has the muzzle velocity I needed for a flat trajectory. It was inexpensive enough to buy in bulk. I also love that the cases are perfect for reloading, as I took up handloading shortly after getting my new AR.

In my personal experience, X-TAC PMC 55 grain FMJ ammo usually shoots around 1-1.5 MOA. I’m not an expert marksman by any means, but I feel these groups are indicative of the ammo’s potential. The PMC X-TAC 62 grain LAP (M855 clone) ammunition suffers from the same accuracy issues as legitimate M855, holding around 2 MOA in my hands.

“LAP” stands for “light armor piercing.” The bullet has a steel penetrator core, just like green tip M855 ammo used by NATO and the U.S. military. Although it is not considered armor-piercing (according to the ATF’s official definition, at least), it can damage steel targets or baffles. Make sure your gun range allows these types of rounds before attempting to carry it into their premises. Many commercial ranges take issue with bullets that can attract a magnet.

All in all, this is great ammo that can be had for a good price. It feeds and functions properly, and doesn’t leave excessive amounts of carbon fouling in the barrel. It’s accurate enough for the needs of shooters who are happy to consistently punch holes in paper or clang steel targets.

Since this PMC ammunition is about as close to Mil-Spec as you can get, it’s good for long-term storage and stockpiling. I don’t know about you, but for bulk ammo, I don’t think I could ask for much more.

What’s It Best For?

PMC X-TAC 5.56 ammo is best used for plinking, target practice, and long-range shooting. Its low price point makes it easy to buy in bulk to store away for an SHTF situation, and its sealed primer pockets make it resistant to the elements. As PMC has extremely strict quality assurance control standards, this ammo is excellent for use in any of your 5.56 rifles. PMC ammo is also loaded with Boxer primers and high-quality brass cases, both of which make it excellent for reloading.

Disadvantages

As this ammo is imported and extremely high-quality, it is a few pennies more expensive per round than Lake City surplus or PMC Bronze. Accuracy for PMC X-TAC 5.56 is reported to be around 1.5 MOA. If you need sub-MOA accuracy for extremely long-range shooting, you’ll likely want to invest in X-TAC Match or other match-grade ammo. Also, these rounds’ bullets are not designed to expand on impact, making them a less-than-ideal choice for self-defense.

PMC X-TAC 5.56 NATO 55 Grain FMJBT

PMC X-TAC 5.56 NATO 55 grain FMJBT is your bread-and-butter ammo for any AR-15 carbine or Ruger Mini-14. Loaded with classic 55 grain full metal jacket boat tail (FMJBT) projectiles, these rounds have a muzzle velocity of 3,270 fps and muzzle energy of 1,306 ft-lbs – just like the classic M193 military round.

I’ve found accuracy in my ARs to be around 1.5 MOA with this ammo. Simply put, this ammo will shoot where you want it to so long as you do your part.

As this is a standard lead-core FMJ round, it is perfectly safe to fire at indoor shooting ranges (provided rifle ammo is permitted there).

PMC X-TAC 5.56 NATO 62 Grain LAP

PMC X-TAC 5.56 NATO 62 grain LAP is PMC’s M855 (or SS109) clone. Loaded with a 62 grain light armor piercing (LAP) bullet, this cartridge closely mimics the U.S. military and its NATO allies’ current issue green tip ammo.

Like M855, this round’s bullet has a mild steel core penetrator insert. Such bullets are often banned at indoor ranges, as they pose a greater risk of (A) creating sparks, (B) damaging range equipment, and (C) deflecting shrapnel back at the firing line. With 3,100 fps muzzle velocity and 1,323 ft-lbs of muzzle energy, these rounds are about as close to real M855 rifle ammo as you can get next to Lake City surplus.

Ballistics for PMC X-TAC 5.56 Ammo

Here are ballistics tables for the PMC X-TAC 5.56 ammunition reviewed in the previous section. Please note that the muzzle velocities listed were recorded with a 20” test barrel, and will vary depending on barrel length. (For shooters interested in understanding the full capabilities of 5.56 across different barrel lengths and environmental conditions, our comprehensive 5.56 ballistics guide provides detailed performance data beyond what's shown below.)

Note: This information comes from the manufacturer. Actual ballistics obtained with your firearm can vary considerably from advertised ballistics. Also, ballistics can vary from lot to lot with the same brand and type load.

Parting Shots

I like PMC X-TAC 5.56 ammo. It’s excellent for plinking and target practice, and would serve well in a disaster scenario. It’s reliable, accurate, and clean shooting, which is about all I can ask for when I’m loading up my ammo cans with bulk materiel.

If your ammo cans are a little light these days, make sure you stock up on some PMC X-TAC ammo here at Ammo.com. Check out all our bulk 5.56 ammo if you prefer another brand.

I’ll see you at the range!
