SUBSONIC 223 FPS MANUAL
SUBSONIC 223 FPS CRACK

If you are in the military or law enforcement, you are most likely implementing this style of ammunition for stealth. Question: I understand that subsonic ammunition is going slower than supersonic ammunition, but why would I want to use it?Īnswer: The appropriate answer to this question varies greatly based on what type of shooter you are. The projectile breaking the sound barrier, to them, potentially means the difference between life and death.

Our ammunition was original developed for military operators who rely on the low sound signature to stay alive during covert missions. This is not extremely important when you are utilizing high velocity (supersonic) ammunition, but with subsonic it is very important. The same ammunition fired from a 20” barrel will not travel the same speed if it was to be fired out of a 16” barrel. Barrel lengths also differ from firearm to firearm. Barrels have a unique individuality and will handle ammunition differently. This includes rifles off the same production lines. We need the ammunition to not break the sound barrier in all these varying conditions. Why would we want to load ammunition at around 1,000 fps is the sound barrier is at 1,125 fps? Well, the sound barrier is constantly fluctuating and we have customers utilizing the same ammunition in different environments all around the world. Keeping this number in mind we try to load our ammunition to achieve speeds of 950 – 1,050 fps. Therefore, at a temperature of 68° F (20° C), with low humidity, and at sea level the sound barrier is around 1,125 fps. It will fluctuate based on several factors including temperature, humidity and altitude. But, the sound barrier is not a static barrier.

A bullet that breaks the sound barrier will leave a distinct loud “crack” downrange.

22lr subsonic out of the AR with conversion kit.Subsonic ammunition is ammunition specifically designed to not break the sound barrier and is best utilized in a suppressed weapon. I also want to play with different bullets in the 69+ gr range.Ī heavier projectile version of the 22lr out of and AR that doesn't require a conversion kit, different magazine and the issues associated with 22lr fouling AR and can. I'd like to get it down to and average of 1050 fps (true subsonic level) with a SD of 10 so I am going to play with the powder and start working down in 2/10 increments. I have no idea on what it's max effective range would be but I'd say 200 yards would be a safe bet.

Primer crack is less because of bolt staying closed. About as loud as subsonic 22LR out of the AR w/can.
