This topic is one that has come up a number of times with friends and family, particularly when discussing the AR-15 platform. The .300 AAC Blackout cartridge (known simply as ".300BLK" on the forums) is a relatively new arrival, and has steadily been gaining a following in the enthusiast world.
First off, I'll share the basics of the cartridge. This is essentially a trimmed-down .223/5.56 case, necked down to accept a .30 caliber projectile. The overall length of the cartridge is only slightly shorter (.4mm shorter, to be precise) than that of a 5.56 round, although the projectile is significantly larger. The beauty of this design is it's simplicity; a .300BLK rifle requires only a barrel replacement, every other component is identical to those in the more common 5.56mm and .223 caliber iterations of the AR15.
I would like to point out a problem I see with this, and let this serve as a warning. A .300BLK round is shorter in overall length, and can possibly chamber fully in a 5.56mm/.223 caliber rifle. This means that it's possible to mistakenly put a .300BLK round into a magazine with .223 ammo, chamber the round, and fire the weapon, which would likely result in significant damage to the weapon, and possible injury to the shooter. This is why, when I go to the range, I make sure the ammunition for the .300BLK is kept separately from any other caliber, and I pay close attention when loading magazines. I am not speaking from experience here, I haven't blown up my rifle by mistakenly loading the wrong cartridge, but this is an issue I have heard about happening at least once before.
Now that that's out of the way, let's talk a little bit about the ballistic properties of the round. This cartridge is available in a number of different bullet weights, most common being 115gr. and 125gr. A standard 5.56 NATO cartridge has a bullet weight of only 62gr. Since the Blackout was designed as a .30 caliber solution for the AR15/M16/M4 platform, the ballistics are most frequently compared to those of the original AR15 caliber, the 5.56mm NATO.
For comparison's sake, let's briefly review the ballistic properties of a common AR15 variant:
Caliber: 5.56mm NATO (62gr. FMJ-BT)
Barrel Length: 16 Inches
Effective Range: 500 m (Point Target)
Bullet Velocity: 2,927 ft/sec.
Energy: 1,303 lb/ft.
And the same rifle, chambered in .300 AAC Blackout:
Caliber: .300BLK (125gr. UMC)
Barrel Length: 16 Inches
Effective Range: 460 m (Point Target)
Bullet Velocity: 2,215 ft/sec.
Energy: 1,360 lb/ft.
As you can see, the velocity is lower, as expected, for the .300BLK. Energy is higher, but in terms of bullet drift and drop, the Blackout experiences both at a shorter distance than that of the 5.56. The 5.56, being a much smaller/lighter projectile, doesn't carry as much energy moving past it's effective range, however. The .300BLK above carries the same amount of energy at 700 m, that the 5.56 cartridge does at 500 m. The projectile size and energy increase of the .300BLK also allow for greater penetration of "hard targets" than the 5.56.
Another benefit of the .300BLK is that the original project goals specified that it be suitable for use in a short-barreled carbine outfitted with a Suppressor. A 220gr. subsonic .300BLK is a fantastic round for suppressor use, especially when coupled with a short barrel. With a quality suppressor mounted to a 9" Barrel, you can expect a reduction to approximately 130-135 dB, which is below the 140 dB "Safe Threshold" for unprotected hearing. Supersonic loads, however, are significantly louder, even when using a suppressor, and may result in hearing loss if proper hearing protection is not used.
I will elaborate more on this cartridge, including photographs, within the next several days. I have only one AR15 in my collection now, which is chambered in .300 BLK. I made the switch just over a year ago, and I haven't looked back.
Stay tuned for more updates!

Review: Heckler & Koch USP45 Tactical
Recently, I decided to act on impulse, and picked up a pistol I have always been intrigued by. This is the Heckler & Koch (HK) USP45 Tactical. I spent some time at the range with the USP a while back, but we'll get to that later.
First of all, this is a BIG pistol. It's a full-size .45ACP semi-automatic with a 4.78" Threaded Barrel. The magazine capacity depends on which model you purchase, but most will include 12-round magazines. The USP weighs in at 1.9 lbs without a magazine, and the overall length of the pistol is 8.64". Included with most is a cleaning kit, soft-sided case, two 12-round magazines, and of course, the pistol itself.
Build quality is fantastic, everything fits as you'd expect for a pistol in this price range. The trigger pull is smooth, with a clean break and short reset. I did notice a "catch" in the decocking lever, but nothing more than you'd find in a comparable pistol from another reputable manufacturer. The ergonomics are alright, the grip angle is similar to a 1911, although this feels markedly different, by virtue of the size difference and single-stack vs. double-stack design. The grip design is similar to a 2nd-generation Glock or Springfield XD. The slide retracts easily, with no noticeable roughness.
It's got a threaded barrel, but uses a less-common "reverse", or left-hand thread design, which is rather uncommon. If suppressor use is the primary concern for going with the H&K, keep in mind, you may need to purchase a suppressor specifically for this weapon. The raised sights are designed for use with a suppressor, which is an often-overlooked addition by many suppressor users.
If you are planning on using a weapon-mounted light, however, one thing to consider is the rail design employed on the USP. H&K uses a proprietary rail design, and is NOT compatible with most off-the-shelf weapon lights for this reason. If you want to use a weapon light on this pistol, you only have two options: Buy the Insight USPC light made specifically for the USP, or purchase an adapter, and use a standard weapon light (Surefire X300, Streamlight TLR-1/2, etc.). The USPC light is about $190 new, whereas a Streamlight TLR-1 can be found for around $100. If you go with the rail adapter, holster selection just became a whole lot more difficult, and you may need to go with a custom holster.
When I took the H&K to the local indoor shooting range, I brought along a box of Winchester FMJ ammunition, which has recently become my go-to choice for range ammunition. I also brought a box of 50 rounds of Winchester Ranger .45ACP Jacketed Hollow Point ammunition, since my intent was to carry this particular ammo, and wanted to at least put some rounds downrange to familiarize myself with the way the pistol handled it. I was not disappointed.
With the target about 15 yards from my shooting position, I was easily able to place all 12 rounds right where I wanted them. My grouping was similar to that of my duty weapon, a Glock 22 .40S&W pistol, which I've put hundreds of rounds through. All 12 rounds hit within 8-10" of the center of the target. The targets I use for these range trips are usually standard law-enforcement silhouette targets, and every round fired at this distance would have resulted in significant damage to an attacker, given all other factors were equal (which we all know, in a self-defense situation, is rarely the case. . . )
I replaced the target with a fresh one, and put it at 25 yards from the bench. In a standing, unsupported position, using my normal two-handed grip, I was able to place all 12 rounds of the 2nd magazine on the target. This pistol fired accurately, the sights were right where they needed to be, and handling the pistol was just as easy for me as handling my primary carry pistol. Every round went where I intended it to, and the smooth trigger pull lended itself quite well to preventing anticipation. Overall, the USP was a fantastic shooter, accuracy was more than adequate for the distance I was shooting, and reliability was not a concern. I put 150 rounds of ammo through the USP that day, and did not experience any malfunctions.
Overall, I'd say the H&K USP .45 Tactical is a fantastic pistol, it is accurate, easy to handle, and is very reliable. I'll detail the positive and negative aspects of the pistol below. Remember, these are simply my observations, I'm not endorsing or condemning this pistol in any way.
Pros: Accurate, simple operation, reliable, and low-maintenance. Not to mention, aesthetically, it's a fine looking pistol.
Cons: Heavy, bulky, difficult to conceal, holster selection is limited, proprietary rail, proprietary barrel threading.
The Final Word: As a target pistol, this pistol does a fine job. If you are looking for a concealed-carry pistol, you might want to keep looking. Even given the proprietary barrel threading, light rail, and difficulty in finding holsters, this is a fantastic firearm, and is arguably one of the best combat pistols ever made. From a practical standpoint, I personally wouldn't use this pistol for anything other than target shooting, or open carry. From a firearms enthusiast standpoint, I appreciate the weapon for it's simple design, reliability, accuracy, and aesthetics. In the end, you are the only one who can decide whether or not to purchase this particular model. You won't miss much if you don't, but you won't regret it if you do. Either way, this is a fantastic shooter, and I really enjoy it.

Gun Control: Will It Solve Anything?
In response to the senseless shooting deaths of 27 people at the hands of a psychopath last month, President Obama signed 23 Executive Orders on Wednesday, January 16th, 2013. The President also urged Congress to pass into law an Assault Weapons Ban, universal background checks, and magazine capacity limits. What our politicians are able to come up with is not quite clear yet.
The proposals I've heard about so far have run the gamut from reinstating the 1994 Clinton Assault Weapons Ban to an all-out confiscation/forfeiture of any weapon with a single "military-like" characteristic. We've all heard the same arguments from both sides. "Think of the children!" and "We need more guns in schools!" immediately come to mind. What I don't agree with is the fact that politicians, our representatives in government, are using this tragedy as a soapbox upon which to preach their agenda. The knee-jerk reactions from the Left are forcing the Right to respond, which turns a tragedy into a political circus, which I personally find despicable.
Regardless of my personal feelings on the matter, the fact is simple. There is a lot of talk of taking immediate action, and several things have already been done in response to this event. I'm not here to try to scare you, or inform you of what's going on, because I believe it is your job to look at the information and come to your own conclusions. It's not my place to convince you to agree or disagree with my opinion. I will, however, strongly urge you to make your opinion known to your representatives. If you think there should be no further gun control measures taken, write them a letter, make a quick phone call, send an email. If you believe that the solution to the problem at hand is to eliminate assault weapons, restrict magazine capacities, and require stricter background checks for every firearm purchase, let your representatives know.
On the other side of the coin, not only should you let your representatives know YOUR opinions on the matter, but you should make an effort to learn THEIR stance as well. It is increasingly important for everyone to do their part here. Make your voices heard, and make sure your representatives are representing your interests, not their own.
