![]() It also has the ability to cycle both super and subsonic ammunition without modification. #5.56 subsonic ammo full30 caliber bore, burns its full potential in a 9-inch barrel, and is a much better choice for hunting. 300 BLK offers a wider range of projectile choices, thanks to the. It also shoots flatter, experiences less recoil, and ammunition weighs about 40% less. The 5.56 is half the cost of 300 BLK and is available in more high-end loading suitable for precision rifle fire. 300 BLK and 5.56 NATO are intermediate-class rifle cartridges for target shooting, hunting, home defense, and plinking. The 5.56 requires a 20-inch barrel to reach peak ballistic performance.300 Blackout vs. 300 BLK also reaches peak ballistic potential from a 9-inch barrel.30 Cal and 5.56 Suppressors The 110-grain rounds are supersonic, and the 220 subsonic.Ī subsonic round is much easier to suppress, and much quieter when suppressed. 300 BLK does a lot the 5.56 can’t.įirst off, it’s a very versatile load with projectiles weights ranging from 110 grains to 220 grains. 300 BLK has easily been the most successful new caliber in the last 20 years.īesides the easy conversion between 5.56 and. The AR-15/.300 BLK combo does this markedly better than the 5.56 NATO. You need a hard-hitting, short, light, and quiet, gun that will own 0 to 300 yards. 300 BLK is really what two long protracted wars in the Middle East have taught us about the modern gunfight. What you have now is the ultimate short-range thumper that will feed both supersonic and subsonic ammunition and get its full ballistic potential (complete burn of the powder) from a 9-inch barrel. 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.It is then stuffed with fast-burning powders and any number of bullets weighing from 110 to 220-grain. 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. It was during that time we recorded this demonstration video. 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. #5.56 subsonic ammo trialAfter 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. The heaviest projectile I had at the time that would stabilize at subsonic velocities was a Speer 70 grain semi-spitzer. 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. ![]()
