SIG Sauer Announces Supersonic .300 Blackout Ammunition

SIG Sauer has announced a new addition to its nascent ammunition line: Supersonic .300 Blackout. Loaded with 125gr Sierra MatchKing projectiles, this load rounds out the SIG-branded .300 Blackout for their MCX rifle. From the press release:

Newington, NH – SIG SAUER, Inc., designer and manufacturer of the world’s most reliable firearms, accessories, and ammunition, is pleased to announce its new 300 Blackout Supersonic Elite Performance Ammunition Match Grade Centerfire Cartridges. This supersonic round features a 125gr Sierra Matchking projectile and, like the SIG SAUER 220gr subsonic 300 Blackout round, is designed to bring out the best in today’s high-performance AR rifles.

The Sierra Matchking projectiles in the 300 Blackout supersonic rounds are renowned for their superior accuracy, flat trajectory and consistent point of impact. The unique hybrid hollow point bullet design also ensures maximum expansion on point of impact. These cartridges feature match grade brass cases and function with standard 223Remington/5.56mm magazines without a reduction in capacity.

“The 300 Blackout is an increasingly popular caliber with target shooters and 3-gun competition shooters, and is also an excellent round for home defense in short barrel rifles, including the SIG MCX and M400,” said Bud Fini, vice president of marketing for SIG SAUER. “Elite military units are also evaluating the 300 Blackout as their primary CQB load. More modern sporting rifle hunters are turning to the 300 Blackout for close-range hunting of mid-sized game, including hogs and deer. We are pleased to now offer our customers both supersonic and subsonic rounds to meet their shooting and hunting needs.”

All Elite Performance Ammunition is manufactured in the United States 

.300 Blackout in its supersonic form is ballistically very similar to the old 7.92×33 Kurz round, both in energy and trajectory. The primary ballistic difference lies in the very long ogive, necessitated for proper feeding from AR-15 magazines originally designed for longer-cased 5.56mm ammunition.

AK- 47 and It's History

Many people who play video games know about the AK-47. It is a staple in some of the biggest first person shooters on the market and in some cases it is the highest ranked gun you can get in the game. It has earned this level of prestige because of its legendary hard knock design and the ability to perform without complaint even after sitting for years. It is battle hardened and used throughout the world and in some of the harshest conditions, but many people do not actually know that much about this rifle. The origins of its design, along with its construction, are why it seems to just keep going even decades after it was pressed off of the line.

The Origins

The AK-47 was designed and created by Avtomat Kalashnikova, who is the AK in AK-47. He was a Russian who designed the rifle in order to give the infantry a more dependable gun in the field. One that could take a beating without much complaint. Now to say that Kalashnikova wasn't influenced by other rifles would be wrong, the AK was heavy influenced by the German Sturmgewehr 44. When you compare the two rifles you can see where the AK inherited some of its design. Also, the 47 stands for 1947, when it was made, and it is tradition that every AK have the year it was made incorporated with its name.

Construction

One of the main reasons that the AK has been such a successful platform is due to the fact that it is a gas powered gun. This means that the gun uses the gasses given off from when it is fired in order to operate the receiver. This allows the gun to be very fast, but it also means that the gun may even operate even after being submerged. This design along with the chromed barrel and receiver meant that the gun was very dependable.

In a nut shell, there you have it, where the gun came from and why it is one of the most dependable rifles in the world.
