Subsonic Match Solid 50 BMG 650gr
Suppressors are all the range in the shooting sports right now and it stands to reason. The noise level developed from rifle and pistol ammunition being fired is a known hearing problem. In Europe, where suppressors (incorrectly called “silencers”) are not regulated, it’s expected that shooters be considerate when enjoying their sport and use suppressors wherever possible. Here in the US, suppressor ownership takes (literally) an act of government to achieve, 6 months is a common wait time, plus fingerprints, photographs, considerable paperwork and an extraordinary background check to achieve. You even have paperwork to deal with in transporting your suppressor “can,” when you want to travel. Assuming your state even allows such ownership. Oh, and don’t forget the $200 fee to facilitate the acquisition process, IN ADDITION TO the cost of the can itself. But the suppressor market is booming, so to speak.
If people are feeling it worthwhile to moderate the noise of their 9mm or .45 pistols, let alone their .300 Blackout (and other) caliber rifles, imagine the potential impact to the chest thumping .50 BMG caliber!
The .50 hasn’t been a big suppressor caliber in the civilian world, to date, unlike the pistol and other rifle calibers. But if there is one caliber that just screams for sound reduction, it’s the .50 BMG caliber. One explanation for this gap is due to the ammunition. To really take advantage of the hearing benefits of a suppressor, you need to eliminate the supersonic crack of the bullet passing out of the muzzle and through the air. The suppressor just deals with the noise of the propellant gas being expelled. (Two different components of “noise” to be dealt with here.)
While the pistol calibers and many rifle calibers like the .300 Blackout have reduced case volumes (compared to the .50) to accomplish subsonic flight, trying to download .50 BMG caliber ammunition to sub-sonic levels has been extremely difficult. Most attempts have been directed at just putting in less gun powder than normal. The risk here is that you get so little powder in the case that you run the risk of catastrophically detonating (rather than controlled burning) of the powder. There is also the problem of so little powder rambling around inside the big BMG case that not enough powder is near enough to the primer at the point of ignition.
One other, brief attempt at a subsonic .50 cartridge solution was to turn the cartridge cases out of solid bar stock, like match projectiles are currently. By starting with a solid piece of brass rod and turning the cartridge case from that, you can control the inside dimensions of the case, like you do with the outside dimensions. From there it’s a (somewhat) simple step to change the internal volume of the case (i.e. change the case wall and head thickness) to achieve less internal volume than a normal cartridge case. That, theoretically, would better hold a reduced powder charge, developing a reduced and more consistent chamber pressure, resulting in a reduced velocity, one reduced to subsonic levels. The company exploring that option had some limited success, but it’s not been followed up to widespread production. Perhaps the advent of polymer cartridge cases, like the .50 BMG caliber Mk323 Ball round, will pick up where that concept left off.
In the meantime, We at Detroit Ammunition Company, concurrently working along with Triple R Munitions, may have just conquered the subsonic .50 caliber cartridge obstacle on our own and while using regular .50 BMG brass cases. The two cartridge designs in question are stock number TRM50BMG725, a Subsonic Controlled Fracturing bullet design, from Lehigh Bullets, 725 grains in weight, and TRM50BMG650, a Subsonic Match Solid bullet, also from Lehigh, at 650 grains. Both cartridges are listed at 1,020 fps for a muzzle velocity.
No surplus powders or primers are used to build our ammunition. The powders that are used are often better than those of many OEM manufacturers, producing the best subsonic round available!
