Having the right ammo is one of the most important aspects of having a good build. I know, optics, lights, slings, etc., are all major, but the build fails completely if the ammo is garbage. Think of it this way: you can hit the gym every day, but if you don’t have the right food to build muscle, everything else is for nothing. 

.223/5.56 Ammo

We try lots of different ammo around here. Spoiler: none of these made the list.

Sounds dramatic, right? Well, ammunition also has a time and place. What if you’re ready to shoot indoors, got everything ready, but took M855 “Green Tip” with you instead of training ammo? Likewise, what if you’re trying to stretch the wings on your rifle, but you bring training ammo instead of 77-grain?

Having the right ammo is key to getting the most out of the build you’ve spent so much on. And that’s what you and I are going to talk about today. All types of ammo from good M855 rounds to training ammo and the right rounds for those who like to throw at a distance. 

What Makes Good Ammo?

Not all ammo is created equal. The best companies ensure they use only the highest-quality materials they can find, while others use their own house-made primers and powders. When done properly, good ammo burns cleaner with better accuracy and consistency. 

And when ammo is just put together as cheaply as possible, you get Winchester White Box. Dirty, nasty brass, and it fouls up your rifle like your toilet on Taco Tuesday. All in all, good ammo is like feeding your rifle Whole Foods, while bad ammo is equivalent to feeding your rifle gas station sushi. 

The Good Stuff

PMC X-TAC 55 Grain

By far, one of my favorite training rounds that won’t run your pockets is PMC X-TAC. These cartridges are made with all in-house materials and are produced using some of the highest-quality equipment in the world by the Korean military.

I love this stuff. Never an issue in my BCM.

All primers, caps, powders, and casings are of the utmost quality, and in my many years of trusting PMC ammo, I’ve yet to have one malfunction. My BCM never fouls, nor is it extremely dirty, even after putting hundreds of rounds down range.

As far as accuracy goes, X-Tac is not going to give you sub-MOA accuracy (that’s what its Match ammo is for), but it will put you on target in a consistent pattern as long as you’ve been training as you should. If you’re looking for bulk training ammo, this is it. 

Hornady Black 

Hornady has a long, long history of making some of the finest ammo you can get your hands on. Everything about the ammo is high quality, from the bullets to the primer and everything in between. Quality is one of the things Hornady has always been great with, and if you’re loading up your AR-15 with Hornady Black, you can rest assured that you’ve got the best.

Hornady Black

I’ve always had great luck with Hornady Black as well.

Hornady Black was designed to be everything a modern sporting rifle would need. In this case, the AR-15 is the sporting rifle in question. It’s not the most accurate ammo on the market, but it is extremely consistent and easy to make good shots with when you dial it in.

Accuracy with this ammo is dependent on you and your rifle setup. I’ve hit 1 MOA groupings with 55-grain at 100 yards, and similar with the 62-grain. The part I love about Hornady Black is that it’s high quality. 

I’m not saying it’s the best, but you won’t be able to tell much of a difference between this and the best as long as you aren’t worried about accuracy too much. 

Speer Gold Dot 

Moving away from training ammo, we have a defensive round. If you’re here looking for a home defense load, this is the one. It’s optimized for peak FBI protocol performance, so you know Speer is taking things seriously.

Used by Law Enforcement and three-letter agencies worldwide, the Speer Gold Dot features a bonded bullet that defeats common barriers but expands upon penetration into soft tissue.

The heavier grain weight lends itself to more power, which is preferred in defensive situations. Regular M193 (55 grain) has been proven to be terrible at stopping targets, owing to how fast it flies and how little it does against the actual threat. 

An expanding round like this spreads its wings and creates more wound channels, meaning more ouch to the bad guy and less to the neighbor’s cat. There are a million reasons why you should be running defensive ammo in your AR-15, and 75-grain Speer Gold Dot is the perfect candidate. 

Black Hills 77-grain OTM

Reaching out and hitting something several hundred yards with an AR-15 is not the easiest feat. 5.56 is light, easily manipulated by the elements, and just not meant for damage over distance. That’s where Black Hills comes in. Making one of the most popular rounds on the market, the 77-grain Open Tip Match is meant for sub-MOA groups and makes you look like a sharp shooter.

The OTM (Open Tip Match) design results from the lead core being poured into the jacket. It does not expand, but the core is meant to give the round a better ballistic coefficient and provide more stability over distance, which 5.56×45 is typically terrible at. 

Black Hills 77-grain OTM is often considered the best 5.56 ammo for distance on the market. There are other rounds with similar ballistics, but this remains at the top spot, against which all others are compared. If distance is your way, head for the Hills. 

See what I did there? 

Conclusion

Now that we’ve gotten through the ammo itself, you should know that a lot of the performance of this ammo is dependent on how your rifle is built to handle it. Barrel twist rates and length are of utmost importance. Heavier (longer) rounds like shorter twist rates due to the extra stability needs, while lighter grain weight (shorter) rounds are not as picky. 

But all of that only matters if you’re shooting for distance, which is a conversation for another day with a ton of different information. Anyhow, these rounds will definitely not be the reason why anything goes wrong. 

Just make sure you have what you need, and buy it in bulk. Some of this ammo is expensive, and it’s always better to buy more. You can never have too much ammo!

Be good and take care.
