BWA 10×100: New Cartridge with 100-Year-Old Roots

BWA 10x100
Mr. Louis “Lou” Murdica, 1991 Bench Rest World Champion testing the BWA 10×100.

Blackwater Ammunition is a company to watch. Today’s announcement is one example of why.

At SHOT Show 2020, Blackwater Ammunition announced a new caliber: the BWA 10×100.

The BWA 10×100 is a new design with some very modern technology, but it has roots that stretch back to World War I.

Before I get into the details, let me share that the initial load developed for this cartridge generates more than 11k ft-lbs of energy at the muzzle. Now, let’s talk about this new monster caliber.

Case

Case dimensions and properties are highly important aspects of cartridge design and load development.

The new 10×100 BWA cartridge has the same base diameter, rim thickness and primer pocket as a .50 BMG cartridge. Additionally, the overall length (OAL) of the 10×100 BWA is the same as the .50 BMG.

In other words, many, if not most, .50 BMG rifles can be converted to 10×100 BWA with a barrel change. The bolt, extractor and ejector all work the same with the 10×100 case.

10x100 BWA

The 10×100 BWA case is 1mm longer than the .50 BMG. That may not seem like a lot, but according to the company, it allows up to 20% more powder to be loaded in each round. But, that may not be the only thing impacting case capacity.

Case technology also plays a role in this new cartridge.

Back in 2018, Blackwater Ammunition and its parent company, Precision Ballistic Manufacturing (PBM), introduced a new case technology that used a two-piece design. According to the company, the pieces were machined from solid metal. This is different than standard brass manufacturing that starts with a small “doughnut” of brass that is drawn (stretched) multiple times.

It is likely that the machined case is stronger than a drawn case. If so, the walls of the case could be thinner and still provide the same strength. Thinner walls would allow for a greater case capacity.

Bullet

As you might expect, the BWA 10×100 sends large, heavy projectiles downrange. How big? How heavy? How fast?

Right now, Blackwater Ammunition only released data on one load, and it is a doozy.

With a 420-grain monolithic Carobronze bullet, Blackwater Ammunition is able to get 3,500 fps at the muzzle. If my math is correct, that puts the muzzle energy at more than 11,400 ft-lbs. Much like the .50 BMG, you can take out lightly armored vehicles with those kinds of numbers.

[Note: If you’re not familiar with Carobronze, it is a dense, homogeneous copper alloy that is often used in the aerospace industry. It is said to offer very low friction and a high surface hardness – 90 points on the Brinell scale.]

In a head-to-head matchup, the .50 BMG can still generate more raw power. For example, the Federal American Eagle .50 BMG pushes a 660-grain bullet to more than 2,900 fps. That’s roughly 1,000 more ft-lbs of energy.

Keep in mind that energy doesn’t dictate accuracy, nor is an established .50 BMG load vs the first load of a completely new caliber a fair comparison. It is, however, an interesting starting point for the inevitable comparisons and discussions regarding these two rounds.

I’ve reached out to Blackwater Ammunition for additional information on the cases and cartridge. As I get additional information, I will share it here.

In the meantime, I hope you chime in with your thoughts in the comments below.

Diamondback DBX – Dual Piston Pistol

Diamondback DBX Review on Range

Diamondback Firearms announced the new DBX pistol at SHOT Show 2020. The new gun is chambered for the 5.7×28 cartridge and has a variety of interesting features that might grab your attention.

So, let’s not dally about and jump right in.

General Information

The new Diamondback DBX is in the general style of an AR pistol, but it should be readily apparent that it is not as simple as that.

Diamondback Firearms manufactured this semi-automatic pistol as a locked-breech design with a dual-piston gas system. I’m looking forward to getting some time with this gun to see how the system is designed.

Unlike some of the alternatives, this is a bottom feeder with the magazines inserting in the AR-standard position. The gun runs on FN Five-seveN 20-round magazines. However, the company has also announced that a second gun that will feed from the Ruger-57 pattern magazines will also be released. One magazine is included.

The 8″ barrel is threaded. It comes fitted with the company’s new DBX muzzle device.

Up front, the forend has M-LOK attachment points on the left, right and bottom for a wide range of accessories. Included with the gun is a Magpul handstop kit. For a gun this short, I like that the company includes this as a standard accessory.

Diamondback includes a side folding arm brace with the pistol. It attaches to the Picatinny rail on the butt end of the gun.

What Gives?

The new Diamondback DBX is one of several new guns recently announced for the 5.7×28 cartridge. Additionally, there have been some new ammo additions like the Speer Gold Dot self-defense load.

Why the sudden surge of interest in this cartridge?

I don’t have any inside information, but I believe all three guns were developed independently. This suggests that the sales and design teams at three different companies reached the same conclusion on the market data they had. That conclusion: there is enough market demand for guns chambered for the cartridge to make the projects financially viable.

So, what happens when three companies move to satisfy the same demand?

Diamondback DBX LEft Side

In this case, I believe it will work out well for all of the companies.

Starting with the Ruger-57, there has been a lot of discussion surrounding the cartridge. When CMMG announced its own rifles and pistols (along with AR conversion kits) in 5.7×28, even more people took notice. With a third company jumping into the pool, it will make a lot of people ask “What am I missing?”

Will those people turn into buyers? I think a lot of them will. With the support of premium ammunition for self-defense, target shooting and small game hunting, the cartridge suddenly has a life I did not expect to see.

I look forward to a Diamondback DBX review, but what do you think? It is hard to carry concealed – after all, you can’t slip it into a Ruger-57 holster, but for a home defense weapon, it might be a great choice. Are you interested in this cartridge and/or pistol?
