Ideal Situations for the 300 Blackout
The 300 Blackout was originally designed to provide similar performance to the 7.62x39mm Soviet round in an AR-15 with a standard magazine and bolt. This was based on real combat experience in which the standard 5.56x45mm NATO round did not provide sufficient knockdown power at the short ranges of urban combat. Similar problems have been experienced with 9mm submachine guns.
An agile, short-barreled M4 carbine in 300 Blackout addresses the deficiencies of both. This makes the 300 Blackout an outstanding home defense round. However, since its development ten years ago, the caliber has been developed and tested for hunting at mid to long-range with outstanding results thanks to its 30 caliber knockdown power.
It works perfectly on varmints and mid-sized game. Bullets with good expansion will take care of large game, too. In fact, it is difficult to find a more versatile rifle round.
Qualities of Great 300 Blackout Ammo
Several qualities go into a really reliable, great round for this weapon. Here are a few to keep in mind.
One important quality of any ammo is that it should be suited to your intended use. With 300 Blackout, you have options from low subsonic rounds to high-powered long distances ones. The former are great for tactical situations with a suppressed rifle. The latter are more suited to long range shooting and hunting.
The best ammo will feed reliably in your firearm. Most ammo tends to work fine, but sometimes you get an ammo and rifle pairing that just don't like each other. One mag of testing should be enough to see if there is a problem.
The best ammo will also fire safely and reliably. Misfires can be dangerous as they may go off after a short delay, while Bubba is peering down the bore to see what went wrong. Always go with reputable manufacturers to avoid this problem. You will want to take your ammo to the range to test the accuracy. No matter how reliable it is, if shot placement isn't consistent and you can verify that the problem isn't you or your rifle, you are not shooting the best 300 AAC ammo.
