At the 2017 Association of the United States Army annual meeting, Korean optics maker DI Optical was showing off many of their familiar products, but also had on display an interesting looking rifle attachment from a company called Jammer Korea. The attachment, named [Read More…]
Technology research and development company Battelle has announced the second generation of its DroneDefender anti-drone weapon. First released in 2015, the DroneDefender’s initial configuration appeared to be essentially a radio jamming apparatus attached to an [Read More…]
In yesterday’s article, we took a look at examples of two different methods of design, which I called “preference-driven” and “process-driven”. For these examples, I supposed two engineers from two different cultures – called [Read More…]
If you were designing the next small arms round, how would you do it? What methods would you use to determine its physical characteristics and performance attributes? How would you know what was too large or too small, too powerful or too weak? Perhaps more critically, [Read More…]
It has been a little while since we visited the subject of modern personal defense weapon calibers, so to start it off again we’ll be taking a look at a new high velocity round that is only a few years old: Armscor’s .22 TCM. This round was reportedly [Read More…]
It is not only the West that has developed small caliber, high-velocity pistol-compatible personal defense weapon ammunition; in the early 1990s, the People’s Republic of China also developed such a round. Called the 5.8x21mm DAP-92, it fires an 0.229″ [Read More…]
When I started the Modern Intermediate Calibers series, I did not expect it to grow as large as it has. The initial plan was for 7 major calibers, which grew into well over 20, and the spinoff Modern Personal Defense Weapon Calibers, which itself will have at least 20 [Read More…]
So far in the Modern PDW Calibers series we’ve talked about small caliber, high velocity PDW rounds like the 5.7mm FN and 4.6mm HK, and we’ve tackled larger, punchier calibers like the 10mm Norma Auto and the 7.5mm FK. However, we still have not tackled the [Read More…]
Oh yes, it’s that time. The 10mm Automatic, what hasn’t been said about it? Well, a decently sourced article about its history*, maybe, but that’s for another time. Right now, we’re considering the 10mm Auto (or 10mm Norma as it’s more prim [Read More…]
Since we’ve discussed the .30 M1 Carbine caliber, it is probably only a matter of time before someone mentioned another .30 caliber round used by the Allies during the Second World War, that being the 7.62x25mm Tokarev. The round is a turbocharged derivative of [Read More…]
The US .30 cal M1 Carbine is one of the most important developments in the personal defense weapon story, being one of the very first* intermediate calibers to be adopted as standard issue by a nation, and arguably the first purpose-designed PDW caliber in history. [Read More…]
Today on Modern PDW Calibers we’re going to look at what might seem like a humdrum round, but which represents an important performance band for the modern personal defense weapon. That round is the 5.56x30mm MARS, a purpose built “micro assault rifle” [Read More…]
It’s been a while since we’ve done one of these Modern PDW Calibers installments, but we’re back, and today we’re looking at a very new round on the market, one that is currently making some pretty big waves in the pistol world. I am talking of [Read More…]
Since we’ve covered the two most prominent PDW rounds of today, I want to take a quick detour and look at an interesting – but obscure – personal defense weapon/assault rifle round from history. After World War II, the apparati of the German war [Read More…]
We’ve discussed a lot of different rounds in this series so far, but today we’re going to discuss a round that actually has a shot of being adopted (at least in some form) by the United States military as a next-generation small arms ammunition [Read More…]
In the mid-1950s, the People’s Republic of China followed the Soviet Union’s example and adopted the intermediate 7.62x39mm round. This decision substantially helped to promote that cartridge’s ubiquity throughout the world, as millions of cheap [Read More…]
In the late 1950s, after the first public demonstrations of the AR-15 and its new small caliber, high velocity cartridge, the Soviet Union took notice of the radical developments in military .22 caliber rounds in the United States. By 1959, four years before the [Read More…]
At this point we’ve looked at the data for seven intermediate calibers currently on the market, each of which is – one way or another – influencing the discussion around the question of what next generation military rifle caliber will be. Those rounds [Read More…]
Since we know that gunshot wounds follow physical laws – Newtonian mechanics, specifically – we can use physical quantities to describe what happens to a bullet when it enters a fleshy target. In a previous post, we were introduced to three physical [Read More…]
In a recent post, I discussed four ballistics myths that I’ve heard over the years, and why they are just that – myths. One of these was the myth that the momentum of a projectile is equivalent or otherwise indicative of the stopping power of that [Read More…]
