Discreet Ballistics – Precision Machined Projectiles
Even though shooting quietly is a passion of mine, I have yet to break into the world of suppressed 300BLK. I’m also not ashamed to admit that I had to review the definition of ballistic coefficient (BC) before writing this post. What I learned in my limited research is that there are companies who are working to push the boundaries of precision subsonic shooting. One of these companies, Discreet Ballistics, is a New Hampshire-based manufacturer specializing in the design, development and production of subsonic rifle ammunition and accessories.
“When Discreet Ballistics started started in 2015 we had every intention of choosing a bullet from one of the known bullet manufacturers to incorporate into our expanding subsonic 300 Blackout,” said owner David Stark.
However, after testing every expanding 30 caliber subsonic bullets available on the market the company found some serious deficiencies. When testing and evaluating they focused their analysis on three areas: accuracy; bullet action (expansion); and projectile mass retention upon terminal impact. What became clear during their tests was that the best subsonic projectiles on the market only excelled in one or two of these areas.
Rather than choosing from what was available, Discreet Ballistics decided to develop a 30 Caliber subsonic expanding projectile that excelled in all of their requirements. Last year, Discreet Ballistics partnered with Peregrine Bullets to develop and manufacture an entirely new monolithic copper subsonic expanding projectile.
Peregrine Bullets usee Swiss-type lathes to manufacture and prototype commercial target, hunting, and self-defense projectiles. In order to analyze bullet flight characteristics, Peregrine uses OpenFoam software which makes it possible to customize their Computational Fluid Dynamic (CFD) analysis. Long story short, technology allows the company to visualize drag and other forces at work on Projectiles at different velocities.
The new projectile is known internally at Discreet Ballistics as the Selous bullet and it will be available as premium loaded ammunition in mid-to-late Spring 2017. The projectile weight is 188 Grains. The cartridges are available for pre-order now at www.discreetballistics.com.
Currently available for purchase at www.discreetballistics.com are 50 round boxes of 190 grain 300 blackout subsonic cartridges that are ballistically matched to the Selous cartridge in 300 blackout subsonic. We’re offering these cartridges so that our customers will be able to practice with less expensive lead core FMJ ammunition.
The Discreet Ballistics’ 300 AAC Blackout 190gr Subsonic Target Load is intended for use in semi-automatic and bolt action firearms chambered in 300 Blackout. This round has been thoroughly tested to function in both pistol and carbine length gas systems. Discreet Ballistics gives its customers the option of choosing these loads for use in 16″ barrels or 7-11″ barrels due to significant variability in muzzle velocity depending on barrel length.
Discreet Ballistics designed this target round as part of a premium two load system that complements the Discreet Ballistics 300 AAC Blackout Hunting/SD system which utilizes a machined copper projectile (Selous bullet).
Specifications:
- Brass: New Jagemann – 300BLK Sub – Factory Annealed
- Bullet: 190 grain HPBT FMJ
- Bullet Ballistic Coefficient: .530G1
- Average Muzzle Velocity at 50 Deg F: 1040 FPS

I think the colored CFD picture shows pressure, not drag. Red on the front is drag. Blue on the back is drag.
I do have a suppressed 300BLK SBR, I won't hunt with subsonics :(
I bought a SilencerCo Hybrid for .460 projectiles and wish SOMEONE made a 16" 458 SOCOM 1/14" twist bolt/lever gun-(Hello Ruger American with AI mags)
