Hornady'southward 300 Blackout 190-grain Subsonic – Lives Up To The Hype

It seems to have all started with a whisper. The 300 Whisper that is. This unique round was developed back in the early 90's equally a wildcat cartridge by J.D. Jones of SSK Industries. It was developed equally a multi-purpose cartridge, capable of utilizing relatively lightweight bullets at supersonic velocities as well every bit heavier bullets (200–250 grains) at subsonic velocities. As with many wildcat rounds though, it drifted off to obscurity seemingly destined for nothing more than than a page in the history book. That inverse though when Advanced Armament Corporation (AAC) revived the 300 every bit an alternative to the standard 5.56 round. They only wanted more than punch and the 300 had the potential to brand that happen. The end product of their work was the 300 Blackout circular.

With the launch of the new round came a clamoring for AR-15 rifles chambered in the .300 Blackout cartridge. The rest, as they say, is history. Several manufacturers have jumped into the 300 market place and accept built some infrequent guns to run this unique ammunition. Over the last several years though, another tendency has developed. People love to shoot the 300 Blackout suppressed. The heavier bullet combined with an AR platform only screams for a suppressor. Of course, suppressors lose much of their magic if the round is still supersonic. With that, the cry went out once more every bit the 300 shooters looked for solid, reliable 300 Blackout subsonic ammunition. What they wanted was a round that allows shooters to take advantage of these platforms without sacrificing projectile performance.  Enter Hornady and their team of Jedi similar engineers. Their goal was to produce the best 300 Blackout subsonic armament on the market place. After extensive pattern review and testing, I believe they have achieved just that — Enter the Hornady 300 Blackout 190-grain Sub-X Subsonic (Subsonic – eXpanding). "Hornady's Subsonic ammunition was developed because of the popularity of suppressors, as well every bit the need to take new bullet designs that are specifically designed for subsonic operation," Hornady Ballistics Engineer Jayden Quinlan said. The round is well idea out and a serious performer.

Repose And Effective

With any advancement in design, at that place seems to ever be a central point, which the product is developed around. In the instance of the 300 Blackout 190-grain Sub-10 Subsonic the central point was the visitor'due south new Sub-X bullet. It is designed to non just exist quiet only to provide effective final performance at subsonic speeds. The round is manifestly designed for more than just punching holes in paper. Their new projectile features a combination of a lead core surrounded past a grooved metallic jacket and tipped with the company's Flex Tip insert. The design of the projectile ensures expansion at speeds as low as 900 feet per second. In addition to its patented Flex Tip, long grooves in the gilding metal jacket of the 190-grain Sub-Ten combine with the bullet'due south flat profile to ensure expansion. The Sub-Ten features a lead core and a cannelure for a positive case crimp for utilise in semi-automatics. Hornady Ballistics Engineer Quinlan shared that "The Sub-10 bullet was designed from the ground up in .300 Blackout to perform terminally as well as to exist a very accurate subsonic bullet."  Once over again though we are reminded the new circular is meant for far more but target do. "With the Hornady Sub-X bullet in the .300 Blackout load, we designed that so that information technology would see the FBI protocol, the FBI protocol consisting of six different tests through intermediate barriers that police force enforcement or the military commonly encounter," Quinlan said. "The Coma is a growing cartridge in popularity in law enforcement also as military applications because of its suppression abilities."

Information technology'south The Real Deal

As with all things though, it looks peachy on paper merely I was curious if it truly walked the walk. And then I grabbed my handy 300 Blackout rifle, almost an entire case of ammo and went to work on the range — I was not disappointed. I was pleasantly surprised to find that the ammo had a very mild report fifty-fifty before I put the suppressor on. While I would not call it hearing rubber, it was drastically quieter than normal 300. In fact, I would recommend this ammunition for those 300 shooters that have not entered the suppressor world withal. Information technology makes shooting much more enjoyable. Everything changed though when I put the can on. The commencement few shots acquired my boyfriend shooters to literally laugh out loud as the gun now produced the much sought later on "pew" sound. Information technology was barely audible with hearing protection. Now with ear pro ditched, the serious shooting began. Two noticeable factors emerged. First was obviously the superior quiet gene of the round. The second was the lack of any muzzle signature. Hornady uses unique powders optimized for subsonic utilise that result in a low wink signature, ideal for either suppressed or unsuppressed performance. Yes, it was that noticeable especially as dusk settled in. I had no feed problems and used a variety of magazines. When running any 300 Blackout I adopt the ETS clear mags because they allow me to see what is loaded and helps avoid mixing ammo. Consider that your warning to know what you are feeding your burglarize.

Performance-wise, the round left the barrel at 1,050 FPS with a hearty 465 FP of free energy. My thoughts turned to the rolling and lightly wooded areas of Eastward Texas and all the hogs that were soon to meet their doom with this ammo. It performed well and is capable of punching tight groups at hunting distances. It is a rare twenty-four hour period that I can honestly say the production lived up to the hype. The Hornady 300 Blackout 190-grain Sub-X Subsonic is a must for anyone serious about the business organisation of 300 Blackout.
