![]() The cosmetic blemish variety was tested here and achieved "pretty" good performance, even though it's Gemtech's ugly duckling. Interestingly, Gemtech offers two variations of this ammo, with one being a cosmetic blemished version of its more aesthetic counterpart. Optimized for suppressed applications, Gemtech's 187-grain subsonic load features a polymer-tipped projectile for optimal expansion. 300 Blackout may be used for hunting at close to medium distances, but humane/ethical game kills become more difficult to make as distances stretch due to lower velocity and kinesthetic shock, as compared to supersonic ammunition. In close quarters situations with friendly personnel, a subsonic round combined with a suppressor will greatly reduce muzzle blast, making it safer for innocent bystanders and easier to communicate with team members. 300 AAC Blackout cartridge, subsonic loads are great for target shooting and home defense or tactical applications where stealth is mission critical. This added weight makes them naturally slower than a 110-grain bullet fired through the same barrel, even if the heavier bullets are charged with the same type and amount of gunpowder as a corresponding supersonic load. 300 AAC Blackout loads usually weigh between 180- and 220-grains. ![]() Manufacturers commonly use low-flash powders in subsonic ammo to further compliment use with suppressors, while also protecting the shooter's night vision in low-light situations. Subsonic ammo also generally produces less felt recoil than supersonic loads. This makes subsonic loads a primary option for use with suppressed firearms. Subsonic projectiles don't produce a supersonic "crack," because they don't break the sound barrier. This ammo is best served for a leisurely weekend at the range when you have an itchy trigger finger. No malfunctions were experienced during testing, however you shouldn't expect to see exceptional accuracy. 223 Rem/5.56 NATO brass, this ammo is sold entirely online and in boxes of 50. 300 Blackout ammo to bang away with at the range, look no further than Freedom Munitions 150-grain FMJ. If you're bargain shopping for factory-loaded. Oath's 140-grain FMJ load is intended for semiauto rifles, however they also have purpose-built Blackout loads for bolt-action rifles as well.ġ0. The result is extremely precise tolerances with nearly zero margin for manufacturing error. In fact, Oath's bullets and cartridge cases are entirely CNC-machined from solid billets of copper, brass or aluminum. It will be exciting to see what types of ammo SIG Sauer unveils next.Īmmunition from Oath is manufactured with an entirely different process than traditional ammo. It also achieved very consistent velocities and sub-MOA accuracy with zero malfunctions. The bullet features a unique hybrid hollow-point design for maximum expansion upon impact. 300 Blackout variety, loaded with a 125-grain hollow-point Sierra MatchKing bullet. Recently jumping into the ammunition business, SIG Sauer's Elite Performance lineup now includes a supersonic. SIG Sauer Elite Performance 125-grain Sierra MatchKing ![]() As tested, it functioned flawlessly and is worth buying a box or two, if for nothing more than pure cool factor.Ĩ. It's also optimized to cycle in semiauto platforms with 1-in-8-inch barrel twists, like the barrel used in our test. Loaded with a 110-grain polymer-tipped Varmageddon bullet, this stealthy looking load uses black nickel plated components. Groups do not seem to close up again until hitting the 180 grain mark.By far the most aesthetically-pleasing ammo on this list, Noveske has teamed up with Nosler to design blacked-out Blackout rounds. Also the modern subsonic specific bullets with petals and huge hollow points would seem to require a "supersonic" approach to use where "subsonic" loading is more like black powder cartridge.Īt supersonic, I have used 125 grain Nosler BTs out to 700 yards with good effect but struggled with mid range weights. There has been a tendency to move towards 1/7 and I can see the logic for flight stability given it should/should make the bullet even more unstable when it hits. This was unlike the 210 Berger which was too stable and ended up producing multiple needle point holes. I have had 240s pull internal material out on their journey. The ideal exit hole should look like a knife wound. When it hits a target, to get best effect, you want it to start tumbling within an inch. They need to be stable in flight but then turn rapidly unstable upon hitting an object. The whole point of conventional heavy bullets leaving the barrel at 1050fps is that they should exist on the ragged edge of stability.
