Find a variety of subsonic, standard, and rimfire ammo on OpticsPlanet! We offer major brands, muzzle devices, and free shipping on orders $49 or more. There are standard loads as well like subsonic 22, subsonic 223, and subsonic 9mm. Yet, subsonic ammo isn't limited to specialty cartridges. With a 125-grain bullet, the result is a muzzle velocity of 2,215 feet-per-second with 1,360 foot-pounds of energy. 300 BLK pairs a large-caliber bullet with a smaller casing. 30-caliber cartridge was based on the popular 5.56mm NATO, a standard military round, but delivers a similar performance to the larger 7.62mm NATO, also a standard military load. One of the most popular and effective loads is 300 blackout subsonic.
Therefore, subsonic loads are designed to strike the right balance of velocity and bullet weight. To do that, ammo makers design the round to travel at velocities below the speed of sound, which creates another problem altogether. The goal when designing a subsonic round is to reduce the noise of the initial crack caused by expelling gases. He failed to clean all the cutting fluid out of the can during assembly so when I fired the gun during the demonstration the suppressor spewed large volumes of smoke….go figure.The benefit of using subsonic ammo is that it's quieter than standard ammunition and makes suppressed fire even more effective, but going subsonic poses a number of challenges for manufacturers. On a side note: a friend of mine who manufacturers suppressor gave me a can that he had just completed with a new baffle design for this demo. Please check out and support the people who help make.more. It was during that time we recorded this demonstration video. 2,839,371 views Shooting subsonic 223 basics.
I spent several years running around the country demonstrating the ammo to numerous state and federal agencies but it was never considered anything more than a novelty at the time. I was half way there.Įventually I found a couple bullet manufacturers who made 100 grain jacketed lead core projectiles for me, at a cost of fifty cents a piece, that worked quite well. Every bullet went sideways through the plate but the gun cycled flawlessly and even locked the bolt back on the last round.

With some small degree of confidence I loaded a magazine full of my new creation, put a suppressor on an M-16 with a 14 1/2” barrel and a 1-in-7 twist, fired a few rounds semi-auto then went full-auto into a thin metal plate at 25 yards.
#Subsonic 223 rounds trial
After some trial and error using numerous powders I came up with a load that gave fairly consistent velocities of 1,000-ish feet per second.
Not only was the projectile really ugly but it was slightly banana shape. 224 size die, and made my own 140 grain bullet. So I applied a little redneck-tech and soldered together two of the 70 grain projectiles, base to base, ran them through a. While I had developed a 5.56 load that was accurate and displayed consistent shot to shot velocities, it wouldn’t even budge the bolt of an M-16 rifle. This ammunition is designed to be shot suppressed (Silencer) and truly is 'Hollywood Quiet.' It is engineered for optimal subsonic velocity using a 16' barrel. This is the largest Hollow Point made in.

The heaviest projectile I had at the time that would stabilize at subsonic velocities was a Speer 70 grain semi-spitzer. Beck Ammunition Silent Operator series is engineered to run at Subsonic Velocities (just below the speed of sound) and to be shot with a sound suppressor. I understood the premise that a heavy-for-caliber bullet was needed but nothing off the shelf was readily available. Back in the late 90’s, subsonic 5.56/223 ammo that would reliably cycle an unmodified M-16 or AR-15 was only a mythical beast, at least in the circles that I ran in.
