300 BlackOut Subsonic ammunition
We felt it prudent to dedicate our first blog post to address a few questions we received from our consumers relative to 300 blackout subsonic ammunition.
If you're reading this blog you probably already understand the benefits of the 300 AAC blackout cartridge therefore we will not bore you with facts about ballistic performance or provide you with information you can readily get on your own through a quick Internet search. We'll use this blog post just to address the questions that are brought to us by our consumers.
Let’s back up just one minute and talk about what subsonic ammunition is and is not. When a firearm is fired with standard velocity ammunition, standard meaning above the speed of sound, the audible report from the firearm is several things happening at nearly the same time. The most significant sounds are those heard from the projectile breaking the sound barrier and the expansion of gas creating a pressure wave as the projectile leaves the barrel. A sound suppressor, or silencer as it is often called, slows down the expansion of gas and dampens the pressure wave to reduce the audible report. So with subsonic ammunition the projectile is traveling slower than the speed of sound, therefore there is no noise created from the the projectile breaking the sound barrier. So with that being understood if you shoot subsonic ammunition on a firearm without a sound suppressor you will still hear quite a loud noise from the expansion of gas creating a pressure wave. Although with a sound suppressor attached and utilization of subsonic ammunition you will hear a very small noise from the expansion of gas and the action of the firearm. Its quite enjoyable to think that the loudest report maybe the projectile striking the target down range. Please also understand that sound suppressors create additional back pressure for the operation of the firearm and that subsonic ammunition is not intended for use with out a sound suppressor.
In dry air at sea level at 68°F the speed of sound is 1125 FPS, and the speed of sound varies based on temperature, humidity and elevation so in consideration of these variables we load our ammunition to the below specifications account for variables our product may encounter in the field.
300 AAC Blackout Ammunition, Subsonic 220gr Sierra MatchKing = 1040 FPS at sea level at 72 °F
300 AAC Blackout Ammunition, Subsonic 208gr Hornady V-Max = 1030 FPS at sea level at 72 °F
Another question we often get is, “What firearms do we test ammunition with?”. Gorilla Ammunition has a state-of-the-art ballistics lab equipped with Ohler acoustical targeting and pressure barrels and measurement equipment allowing us to gather pressure data and velocities on a specific load. Even with the sophisticated equipment we publish our muzzle velocity data from a 16 inch AR style barrel. This is a good standard available to many of our consumers and nearly replicates the conditions our product will be exposed to in the market place by our consumers. Therefore if a consumer is using a shorter barrel and still would like to achieve subsonic velocities we will still have our projectile remain subsonic. Conversely most consumers shooting subsonic any ammunition traditionally will not use a longer than 16 inch barrel even in consideration of that fact we try to keep our standard muzzle velocity low enough to accommodate for increases in barrel length and variable atmospheric conditions.
300 Blackout Subsonic ammunition and bolt action firearms. Another question that seems to be coming up more and more frequently is relative to the use of our subsonic ammunition in bolt action firearms such as the Remington Model 7 or the AAC branded H&R Handi-Rilfe. While we don’t conduct accuracy or velocity test with bolt action firearms for every load our universal receiver and pressure barrel act much like a bolt action firearm and consumers report great results with our product in bolt action firearms. You can read one such report about the performance of our ammunition in bolt action firearms here at The Truth about Guns.
With that being said that leads us to the next most popular question. “Can I hunt with subsonic ammunition?” Absolutely you can hunt with 300 blackout subsonic ammunition. The type of game you choose to take with 300 BlackOut is up to you and your hunting style, confidence level, and experience.
