Yet, some shooters still wonder if this ammo is the right choice for their 300 AAC Blackout rifle (spoiler alert: it is). So, in this Hornady American Gunner 300 Blackout ammo review, we are going to put those fears to rest and explain why this rifle ammo is a great choice for your shooting needs.
If you’re ready to buy, we have Hornady American Gunner 300 Blackout ammo in stock and ready to ship to your door. Otherwise, keep reading for the full review.
Back in 1949, when Joyce Hornady founded his company, the needs of the American shooter were relatively simple. Most of them were returning from WWII and had experience using a 30-caliber bolt-action or semi-auto rifle.
It makes sense that Hornady’s first major success was a 30-cal 150-grain Spire Point hunting bullet. With so many surplus M1 Garands and 1903 Springfields hitting the market, this bullet mated perfectly with the 30-06 Springfield round, which was already popular for hunting.
However, as time forged on, the needs of the American shooter evolved with the advent of new cartridges and firearms. Sure, most 2A enthusiasts have a semi-automatic rifle like an AR-15 carbine or Ruger Mini-14 chambered in 5.56 NATO, but that same rifle can also be chambered in calibers like 300 Blackout, 6.5 Grendel, 6.8 SPC, or 450 Bushmaster.
Out of all these rifle calibers, the 300 AAC Blackout has been (by a wide margin) the most successful new cartridge adapted to the AR-15 platform. The 300 Blackout (or 300 BLK for short) was developed to increase the stopping power of the AR-15 by replacing the 223 Remington and closely mimicking the terminal ballistics of Russian 7.62×39 rifle ammunition.
Unlike the 7.62×39, the 300 BLK is unique in that it can be fired at supersonic and subsonic muzzle velocities, giving shooters an incredible amount of versatility in terms of ammo selection. Developed to be fired with or without a suppressor, a 300 Blackout will experience a full powder burn in just 9 inches of barrel length, making it an ideal candidate for an SBR (short barrel rifle).
Although the 300 Blackout was initially developed for the military, it has become extremely popular with civilian shooters who enjoy deer hunting with their AR-15 carbine or simply want hearing safe subsonic ammo when combined with a silencer.
Hornady 300 Blackout ammo comes in several different flavors to suit almost any situation. Hornady Black 110 gr V-MAX is great for varmint hunting, Custom 110 gr CX is great for deer hunting, and Frontier 125 gr FMJ is perfect for plinking.
What’s missing is a round that’s great for match shooting and long-range target practice, so Hornady American Gunner stepped in to carry that banner.
Hornady American Gunner 300 Blackout ammo is available loaded with a match-grade 125-grain boat tail jacketed hollow point bullet. These rounds are loaded for supersonic velocities and were developed to offer 300 Blackout shooters an extremely accurate round that wouldn’t break the bank like traditional match-grade ammo.
Hornady matches propellants with each individual cartridge in the American Gunner line to provide ideal pressures for an enjoyable and safe shooting experience. Not only does this provide amazing performance, but it also offers exceptional reliability for gas piston, direct gas impingement, and bolt-action rifle designs.
Available in a wide variety of handgun, rifle, and shotgun loads, Hornady American Gunner is quickly becoming one of the company’s most popular ammo lines based on numerous customer reviews. Thanks to its low cost and high levels of accuracy, Hornady American Gunner looks to make competitive shooting available to all shooters, even those on a budget.
There is no doubt that the 300 AAC Blackout is one of the most popular AR-15 rifle calibers across the USA, second only to the 223 Remington/5.56 NATO (yes, I know they’re different). So, when I sat down to write a review about Hornady 300 Blackout 125-grain American Gunner ammo, it’s safe to say I was pretty excited.
The Hornady American Gunner line of ammunition, as a whole, is an interesting take on meeting the needs of both weekend plinkers and competitive shooters. In the past, shooters who wanted cheap ammo were relegated to primarily full metal jacket (FMJ) ammo, while competitive shooters would typically load up with match-grade ammo.
FMJ ammo is great for saving money as it’s cheap, while match ammo is pricey since it uses premium bullets and is often loaded with tighter quality controls in place. Hornady American Gunner ammo looks to bridge the gap between these two lines of thought and offers match-grade bullets at a price that’s nearly identical to FMJ ammo.
Handgun ammunition is exclusively loaded with Hornady XTP jacketed hollow points, while rifle ammunition is loaded with boat tail hollow point (BTHP) match bullets.
American Gunner handgun ammo is offered in standard pistol calibers, namely 380 ACP, 9mm, 40 S&W, 38 Special/357 Magnum, and 45 ACP. American Gunner rifle ammo is loaded in 223 Remington, 6.5 Creedmoor, 308 Winchester, 7.62×39, and of course, 300 Blackout.
Regarding the 300 Blackout offering, let’s start with the bullet and work our way back.
The 125-grain bullet weight is extremely popular with 300 BLK shooters who like to shoot at supersonic velocities. This bullet offers a great balance between muzzle velocity, trajectory, and ballistic coefficient, making it a great all-around choice for target shooting.
However, one shortfall of the 125 gr BTHP bullet is that it is a poor choice for big game hunting. Even though the projectile uses an open-tip design, this hollow point is designed for aerodynamics only and will not offer much expansion on impact. Therefore, this 300 Blackout ammo is only useful for popping varmints like coyotes and groundhogs, but make sure to check your state and local laws before hunting with match-grade ammo.
The 300 Blackout is becoming an extremely popular caliber choice for deer hunting, and if this is something you’re looking to do, I’d recommend checking out the Hornady Custom 300 Blackout 110 gr CX or Fiocchi 125 gr SST as these are designed for whitetail and hog hunting.
I would be cautious using Hornady American Gunner 300 Blackout ammo for self-defense as well. That match-grade BTHP is going to behave like an FMJ in terms of terminal ballistics, so if you did have to employ the round to defend your life or home, it would likely over-penetrate.
In terms of muzzle velocity and kinetic energy, Hornady 300 Blackout ammo is on par with their competitors like Winchester, Federal, and Remington.
However, what Hornady American Gunner 300 Blackout ammo offers you over the Big 3 (listed above) is that it provides shooters with match-level accuracy at nearly the same price as other companies’ FMJ ammo.
Although price is always important, another aspect that I love about this ammo is how Hornady built it with a “ground-up” approach regarding their powder choices. Although Hornady is often rather secretive about what gun powders they use, they state that powder selection is based on not only performance but also the rifle the ammo will be used in.
This means that American Gunner 300 Blackout ammo should cycle perfectly in your AR-15 or any other 300 Blackout rifle regardless of barrel length or gas system.
For the other cartridge components, Hornady always loads their ammo in high-quality brass cases that are Boxer-primed, meaning they are perfect for reloading.
Would I be happy to open up a box of this ammo and load it into my 300 BLK AR-15 for some target practice? Absolutely. This ammo offers incredible performance at a reasonable price point, and in this market, that’s something you simply cannot ignore.
I’d have no problem recommending this ammo to anyone who wants to shoot their 300 Blackout rifle recreationally or is looking to shoot a 3-gun match, as it will provide you with the accuracy you need for both close and long-range shots. And in the end, this is what the 300 Blackout was designed to do!
American Gunner 300 Blackout 125-grain ammo is amazing for target shooting, varmint hunting, and 3-gun competitions. The 125 gr match BTHP projectile is extremely accurate and perfect for shots ranging from 3 feet to 300 yards.
And the best part? This ammo is affordable enough that you won’t need to sell a kidney to order a case or two! Making it a great option for plinking or for a fun day of shooting at the range.
Although a jacketed hollow point bullet is ideal for handgun self-defense rounds, the 125 gr BTHP bullets used in American Gunner 300 BLK ammo are not designed for expansion. This makes these rounds an inappropriate choice for big game hunting and less than ideal for self-defense due to the risk of over-penetration.
Furthermore, the allure of the 300 Blackout rifle cartridge is its ability to be shot at supersonic and subsonic muzzle velocities, and the American Gunner line of ammunition currently does not offer a subsonic load for the 300 BLK.
As much as we love ammo, we understand that no manufacturer is perfect. Here are some of the pros and cons of Hornady American Gunner 300 Blackout ammunition you should be aware of.
- Brass cases perfect for reloading
- Great for competitive shooting
- Match-grade hollow point not ideal for big game hunting
- Better options are available for self-defense
