If anyone has flipped through an American shooting magazine, you will have noticed that the yanks sure do love their AR-15 based semi-auto’s. And in all honesty, why shouldn’t they? It’s a reliable platform that has been highly appreciated by American troops since they were first carried into Vietnam. Although there were a few problems with early production guns, over the years they have been modified into the futuristic weapons that we see advertised today. The Americans use their AR-15’s for everything from home defence to competition shooting and it’s this varied use that has led the development of a few new cartridges along the way.
The .300 Blackout is the newest cartridge and perhaps the most appealing. The .300 Blackout (300BLK) has been specifically developed for use in AR based platforms with only minimal amount of modifications. There is no need for change to the magazine and capacity is the same as its original cartridge the 5.56x45mm or the .223 Remington. The bolt face also remains the same and the only required modification is the barrel itself. So, the cartridge has been successful in its suitability for the AR platform, but how does it preform?
Users of either 30/30 Winchester or the 7.62×39 Military cartridges aren’t going to notice any difference in terms of real world performance. With the choice or either sub or supersonics loads, the cartridge has a lot in common with the .300 Whisper. In fact, Remington is so sure of its success that they have brought out factory ammunition suited to both hunting and target type applications.
There has been (and always will be) a lot of debate in Australia as to whether or not we should be allowed to own semi-automatic firearms. Personally, I can see a lot of potential for hunting and competition uses. Few could argue the effectiveness of a semi-automatic when it comes to eradicating mobs of feral pigs.
I don’t have enough room here to cover all the information available on the .300 BLK. The below link has everything covered and is definitely worth a read.
