For precisely this reason, hunting with subsonic 300 blackout is generally not advised in most scenarios unless you’re taking on wild pigs or smaller sized game within short distances. Without the velocity of supersonic rounds, subsonic 300 Blackout rounds are not able to routinely make clean shots against large game. This purpose excludes taking down big game effectively and ethically. Subsonic 300 Blackout rounds perform extremely well for their intended purpose.
If this is a primary concern and you think you'll be shooting at targets within 100 yards then subsonic rounds complimented with a suppressor device is worth exploring. Whatever you shoot at will be able to know they’re being shot at immediately and they'll react appropriately. Supersonic ammo can be used with a suppressor device to trap the gasses that exit the muzzle, but it won’t be any good for the sound of the projectile splitting the sound barrier. A combination of 300 blackout subsonic rounds and a suppressor device means being able to retain all your senses in an outdoor environment while even dumping your magazine - includes the added benefit of not disturbing others within the area. These advantages are powerful features of subsonic rounds and are made the most effective when applied with a suppressor device. Subsonic 300 Blackout holds more power than 9×19mm while retaining equal ratings of decibel while suppressed. Subsonic rounds hold two advantages over supersonic rounds: quietness and less recoil. These two factors make suppressed supersonic rounds very effective and an attractive choice in confined close quarter environments. Additionally, the lighter recoil also allows users to make faster hits on target in succession. A heavier grain, typically around 180-220 grains, introduces more weight to the projectile, preventing the bullet from exceeding speeds that would break the sound barrier like a supersonic round normally would.
Depending on the load, some 300 blackout subsonic rounds are quiet enough to comfortably use without ear protection. The loudest factors from using suppressed subsonic ammunition comes from the sound of the bullet impact and the bolt carrier group cycling back and forth (when using AR platforms). Subsonic rounds hold one key advantage, they run really quiet when suppressed. A bullet traveling at higher speed means more energy that can be transferred to the target upon impact, more effective range, more tolerance to drop and wind drift. They are also more likely to be available than subsonic round stocks. As supersonic ammo means using a lighter-weight grain (typically less than 180 grain), they’re no doubt the less expensive choice of rounds to train and plink with. Supersonic rounds are the standard rounds most shooters are familiar with as they are the more practical rounds for most applications compared to subsonic rounds. Interested in picking up your own suppressor device? 300 Blackout Supersonic If you do plan on shooting suppressed or aiming at targets within short distances then proceed with the 300 blackout platform. If not, and you need to hit targets at distances past 3-400 yards then opting to shoot 5.56 NATO instead will save yourself some money. The first question to consider before you ask if you ought to use 300 blackout supersonic vs subsonic is whether or not you plan on shooting suppressed. The industry standard for supersonic ammunition is set at around 1,100 feet per second at sea level under standard conditions. The difference between subsonic rounds and supersonic rounds, as implied by their etymology, remain in their ability to break the sound barrier - determined by how fast the projectile travels.
#Supersonic vs subsonic full#
For those 'go loud' engagements you could opt for supersonic rounds to take the ballistic advantage of full power rounds. You could run with subsonic rounds for quiet engagements while equipped with a suppressor to maintain the element of surprise and your hearing. 300 Blackout’s greatest edge is the seamless ability for rifles chambered in this caliber to efficiently transition between subsonic ammo and supersonic ammo. 30 caliber projectiles with a greater muzzle velocity than 7.62x39 mm which creates a larger wound cavity. 300 BLK excels greatly with short barrels (barrels as short as 9 inches) and dispenses. Designed for the purpose of close quarter combat for Special Forces. 300 Blackout is an intermediate caliber that performs with a better ballistic capability than 5.56x45mm while retaining the same round capacity using a standard M4 magazine.
