Details
Hornady’s BLACK line of ammunition works reliably in a variety of firearms, making it a versatile choice no matter what types of rifles you’re bringing along to the range or a competition. This 300 AAC Blackout cartridge features a 208 grain A-MAX projectile, and is subsonic so you may enjoy discreet training with it and especially subtle performance while utilizing it in conjunction with a silencer.
The A-MAX represents the totality of Hornady’s thorough research into ballistics and offers several performance enhancing features. The bullet’s swaged lead core is remarkably uniform in density, which stabilizes it in flight, as does its AMP jacket with its virtually perfectly uniform wall thickness. This bullet’s boat tail design and secant ogive profile work in conjunction to drastically heighten its ballistic coefficient, improving its accuracy and flattening its trajectory. Finally, the bullet’s ultra low-drag tip balances its center of pressure relative to its center of gravity to optimize its in-flight stability. Along with this round’s sensitive primer and first run reloadable brass casing, Hornady provides just what is needed to dominate in any competitive shooting event.

I have shot this round from my 10.5", no adjustable gas block (more failure points imo) with a pretty standard grade barrel an shot with previous milspec bcg an now kak side vent bcg an it shoots accurate an reliably. No failure to feeds or extract, I also use 300 blackout mags from Magpul. I have experienced myself an read that others have had issues with heavy subsonics having feeding issues from 5.56 mags. I haven't had an issue since I started using 300 mags. Shootem from my 10.5 and my 16 in. (Posted on 2/26/2025)

I have a Diamond Back 10.5" would not cycle in a new gun, even after a good break in. I installed a quality adjustable gas block, even all the open wouldn't cyle reliably, about 1 of every 8 rounds. By far the dirtiest round i have ever fired bar, black powder. I called the company "Hornady" to inquire, was told it must be my gun.
Worst ammo Hornady has ever produced in my opinion with over 40 years of shooting. (Posted on 2/12/2025)

These rounds wouldn't cycle my 10.5" Triarc with a Surefire suppressor. I tried 5 different brands and weights (ALL Subsonic / ALL 200-220gr). This is the only one that wouldn't cycle. NOT A SINGLE TIME. (Posted on 10/26/2023)

I used this ammunition to function fire a custom suppressed SBR I was building for my company Swan Weapons And Tactics. It functioned well with no malfunctions. The report wasn't bad either as I was firing it without hearing protection without any discomfort. (Posted on 2/22/2023)

I couldn't get my 7.5inch Spikes AR, 16inch Aero Precision AR, or PSA Jakl to run this ammo using a Silencerco Omega 300, Octane 45 and Omega 36M. Made tons of configuration changes with no luck. Works fine in a Bolt gun. (Posted on 1/30/2023)

Q: Is this round sub sonic
Posted On: 4/10/2020 By: Basil allen
A: It sure is. Hornady gives this round a 1,020 fps muzzle velocity out of a 16" barrel, which is 105 fps slower than the speed of sound. Good for a suppressed firearm because of it.
