But given the necessarily less-energetic payloads possessed by subsonic hunting loads, that way of thinking isn’t going to cut it here.
When fired into Clear Ballistics 10 percent ballistic gelatin, the 395-gr.450 Bushmaster Subsonic load traveled more than 24" before coming to rest.Īmmunition that dumps a ton of energy into the target upon impact can often compensate for subpar shot placement, as the temporary wound cavity may damage vitals that the projectile itself did not. While I don’t share their absolutist point of view on the subject, I do understand their concerns, as subsonic ammunition does shrink the hunter’s margin for error considerably. Unfortunately, up to this point in time, the field results from some of the market’s existing options have been found by shooters to be less than satisfactory, and some diehard hunters I know ardently refuse to use subsonic ammunition for the taking of game as a result of this. at sea level), the available kinetic energy is likewise limited-which makes the trustworthy, effective terminal ballistic performance of the bullet all the more vital-an engineering feat far more difficult at low velocities than it is at blistering ones. With the velocity side of the equation capped by the sound barrier (approximately 1125 f.p.s. handgun suppressor and that has been designed from the ground up to reliably expand inside game even at velocities well below the speed of sound-now that’s something to get excited about!ĭevising an effective subsonic hunting load is more problematic than it may initially seem. Another subsonic Blackout option, even a particularly good one, might not have gotten the blood pumping, but a behemoth 410-gr.45-70 pill that is remarkably pleasant to shoot, safe through a. 45-70 Gov’t-a trifecta of rifle cartridges never previously envisioned (beyond the imaginations of handloaders and a few nichey, small-batch makers) as outlets for subsonic use. Last year, Hornady came from way out of left field to announce three new Sub-X-topped, heavy-for-caliber subsonic hunting loads chambered in. 300 Blackout was appropriate but predictable-which makes what happened next all the more unexpected.
ARE SUBSONIC ROUNDS LEGAL SERIES
Given its reputation for subsonic suitability, starting the Subsonic series with. They’ve been a major part of the cartridge’s appeal since its original development, and options now abound. 300 Blackout ammunition really isn’t terribly huge news these days. That first load didn’t make too many waves upon its introduction to the civilian market (the Department of Defense, on the other hand, recently adopted the law enforcement version for close-quarters use by one of its specialized units) because a new subsonic. So I’ve been curious ever since to see in which direction Hornady would choose to take Sub-X next, and I’m honest enough to admit that my best guess wasn’t even remotely close.
In fact, it’s the ammunition that now habitually resides within the magazines of my primary home-defense carbine. Since its launch, I’ve been quite impressed by this initial loading, finding it to be reliable, capable and an ideal choice for suppressed defensive applications. Hornady inaugurated its Subsonic line back in 2018 with a single 190-gr.300 Blackout offering, and while that product was not its first subsonic load, or even its first subsonic Blackout load, it did mark the introduction of the company’s Sub-X (Subsonic eXpanding) projectile-a bullet tailor-made for performance at velocities well south of the sound barrier.
