Hornady® Subsonic Rifle .45-70 Government 410 Grain Sub-X® – Suppressor-Optimized Flex Tip® Terminal Expansion – 20-Round Box – 82742
Product Description
The Hornady® Subsonic Rifle .45-70 Government 410 Grain Sub-X® Ammunition (82742) represents a revolutionary technological milestone in heavy-bore subsonic ballistics, low-signature terminal mechanics, and suppressed tactical lever-action staging, proudly engineered and loaded by the ammunition innovators at Hornady in Grand Island, Nebraska. Explicitly optimized to provide devastating downrange expansion while remaining safely below the speed of sound, this specialized cartridge eliminates the physical performance limits common to traditional rimmed centerfire brush gun rounds. While typical big-bore hunting ammunition relies on massive velocity spikes that generate an incredibly loud, sharp supersonic crack—which standard silencers are physically incapable of muffling—the Hornady Subsonic matrix establishes a stealthy, high-efficiency operating threshold. This flagship rimmed centerfire payload (090255827422) provides tactical woodsmen, feral hog hunters, and sound-managed marksmen with absolute mechanical, terminal, and auditory authority over their firing workspace.
The foundational terminal superiority of this premium hunting round centers on its patented 410-grain Sub-X® (Subsonic eXpansion) projectile featuring a specialized Flex Tip® elastomer insert nested inside a deep hollowpoint cavity. Traditional heavy hollow points often fail to expand at velocities under 1,100 feet per second, instead behaving like non-expanding solid rounds that sail clean through targets without transferring energy. Hornady overrides this limitation by combining long, pre-formed jacket grooves with the flexible polymer tip, which mechanically forces radical, controlled expansion at velocities as low as 900 feet per second. Built with a solid lead core mechanically bound to a gilding metal jacket via Hornady's signature InterLock® ring, the Sub-X bullet retains over 90% of its total structural mass. This achieves deep, bone-breaking penetration and creates massive permanent wound tracks without fragmenting prematurely upon hard tissue matrices.
The true operational triumph of this American-built cartridge lines within its 100% lever-action safe geometry and suppressor-clean propellant core. Bypassing rigid or pointed tips that present high risks of accidental chain-detonations inside a tubular magazine under recoil, the soft, flexible elastomer tip allows these cartridges to rest point-to-primer with total tool-free mechanical safety while ensuring butter-smooth feeding up the elevator ramp. Pushed by highly stable, clean-burning powder lots meticulously selected for low-flash signatures and tight standard deviations, the massive 410-grain slug leaves the muzzle at a uniform 1,075 feet per second (FPS), hammering downrange targets with a dense 1,052 foot-pounds of muzzle energy. This low-pressure subsonic gas profile drastically cuts down on toxic blowback, minimizes carbon residue on your receiver group, and keeps your internal silencer baffles cleaner for longer.
Includes: (1) 20-Round Box of Authentic Hornady Subsonic Rifle .45-70 Government Ammunition (410 Grain Sub-X Flex Tip Polymer Tipped Projectiles, Low-Friction Cannelured Brass Casings, Suppressor-Optimized Low-Flash Powder Matrix), Packed inside Original Branded Factory Sealed Retail Staging Packaging.
*Administrative Armorer Staging, Handgun Fire Warnings & Regional Statutory Restrictions Guidance: The Hornady Subsonic 45-70 Gov round is an intensive high-mass low-signature hunting asset. CRUCIAL PLATFORM SAFETY WARNING: Hornady explicitly DOES NOT RECOMMEND firing this high-mass 410-grain Subsonic rifle ammunition in revolvers or handguns (such as the Magnum Research BFR or Bond Arms Cyclops platforms); firing these rounds through short, unvented handgun barrels can induce severe pressure variances or bullet squib conditions that risk catastrophic structural damage to the weapon system. **HAZMAT SURFACE SHIPPING RESTRICTIONS:** In strict compliance with Department of Transportation (DOT) mandates, all small arms ammunition must ship exclusively via **UPS Ground or FedEx Ground surface networks and is completely ineligible for air transit methods; purchasers must be a minimum of 21 years of age**. Local municipal and state-level laws strictly regulate online ammunition delivery; shipments bound for **California, New York, New Jersey, Illinois, Connecticut, and Massachusetts must route directly to a verified Federal Firearms Licensee (FFL) or certified commercial ammunition vendor with mandatory identity/background screening loops**. Thoroughly wash hands with cold soap and water immediately following any field fire or bench loading procedures.
Key Features
- Patented Sub-X Flex Tip Expansion: Uses a flexible elastomer tip and pre-scored jacket grooves engineered specifically to expand wide and deliver massive energy transfer at velocities down to 900 FPS.
- 90%+ Structural Weight Retention: Incorporates an internal InterLock® mechanical ring that anchors the gilding metal jacket to the heavy lead core, resisting bullet fragmentation upon heavy bone impact.
- 100% Tubular Magazine Safe: The soft polymer nose tip absorbs kinetic impulse lines inside the magazine tube, completely eliminating the risk of primer-strike chain detonations.
- Whisper-Quiet 1,075 FPS Footprint: Calibrated to cruise reliably beneath the speed of sound, eliminating the loud supersonic crack to fully optimize your sound-suppressed hunting layout.
- Suppressor-Safe Clean Burn Powder: Formulated with advanced, low-flash propellants that decrease gas-blowback pressures and prevent heavy particulate carbon scaling inside internal baffle chambers.
- Premium Reloadable Hornady Brass: Loaded inside precision-drawn, uniform-wall cased brass hulls engineered to ensure perfect chamber sealing, slick extractions, and multi-cycle armorer bench reloading.
