Whether or not you’re stacking coyotes and hogs, a legislation enforcement officer on responsibility, or defending what’s yours, efficiency isn’t negotiable.
The M855 inexperienced tip and Mk318 have been the usual for many years, every with its personal strengths. However let’s be sincere—they’re not excellent. The M855 punches via obstacles however lacks dependable stopping energy. The Mk318 expands higher however isn’t the last word resolution.
Enter the HOP Munitions 62-grain Stable Copper REX. Constructed to outperform each, this spherical delivers devastating power switch, accuracy, and barrier-blind efficiency—with out the downsides of conventional hundreds.
M855 Inexperienced Tip: The Army Workhorse
The M855, widely known because the “inexperienced tip,” is a 62-grain full metallic jacket spherical that includes a metal core. Designed for navy use, its major benefit is penetration, making it efficient towards frivolously armored targets. Key specs embody:
Muzzle Velocity: 3,020 fps Muzzle Power: 1,255 ft/lbs Ballistic Coefficient: ∼.304
Whereas the M855’s metal core enhances penetration, its terminal efficiency could be inconsistent. Fragmentation is unreliable, and enlargement is minimal, limiting its effectiveness for looking or functions the place quick stopping energy is important.
Mk318: The “Silver Bullet”
The Mk318 Mod 0, also known as the “Silver Bullet,” was developed to beat the M855’s shortcomings. Extensively utilized by the USMC, this open-tip match (OTM) spherical gives:
Muzzle Velocity: ∼2,920 fps Muzzle Power: ∼1,186 ft/lbs Ballistic Coefficient: ∼.300
The Mk318’s open-tip design facilitates managed enlargement and fragmentation, considerably bettering lethality with out sacrificing accuracy. Nevertheless, developments in ammunition know-how have pushed the necessity for much more refined choices for tactical, looking, and responsibility functions.
Introducing the Subsequent Era: HOP Munitions 62-Grain Stable Copper REX (Fast EXpanding)
Taking cues from the confirmed efficiency of the Mk318, we’ve pushed the boundaries even additional with our 62-grain Stable Copper REX (Fast EXpanding) spherical. Designed to outperform each the M855 and Mk318, it boasts:
Muzzle Velocity: 2,870 fps Muzzle Power: 1,134 ft/lbs Ballistic Coefficient: .300 Sectional Density: .177
These specs translate into deep penetration, devastating knockdown energy, and distinctive accuracy—making this spherical best for legislation enforcement, navy, coyote and hog looking, and residential protection.
Key Benefits of the Stable Copper REX
Superior Stopping Energy
The Stable Copper REX is engineered for managed enlargement and constant power switch. In comparison with the M855’s metal core and the Mk318’s open-tip design, the REX delivers considerably extra dependable terminal ballistics. It’s the best selection for responsibility use the place stopping energy is critical.
Distinctive Precision
With a ballistic coefficient of .300, the REX gives a flat trajectory and glorious wind resistance, making certain correct shot placement at prolonged ranges—important for legislation enforcement marksmen and navy professionals.
Eco-Pleasant and Sturdy
Made fully from stable copper, the REX eliminates lead contamination whereas sustaining excessive sturdiness. It reliably penetrates obstacles with out structural failure, making it best for responsibility and tactical eventualities.
Versatility Throughout Purposes
Because of its excessive velocity and power switch, the REX is ideally suited to looking small-to-medium sport, dwelling protection, {and professional} use by legislation enforcement and navy personnel.
Closing the Hole on the 77-Grain OTM
Tier 1 navy items have lengthy favored the 77-grain Open-Tip Match (OTM) spherical for its accuracy and devastating terminal efficiency. Its heavier weight gives glorious flight stability, making it a go-to selection for precision capturing. Notable specs embody:
Muzzle Velocity: ~2,750 fps Muzzle Power: ~1,293 ft/lbs Ballistic Coefficient (G1): ~0.370 to 0.380
The 77-grain OTM’s boattail and open-tip design contribute to its superior long-range efficiency. Nevertheless, to maximise stabilization, it requires a 1:7 or 1:8 twist barrel.
For these dedicated to 77-grain hundreds, HOP Munitions additionally gives a 77-grain HPBT choice, delivering the identical precision and efficiency anticipated from this bullet weight.
That mentioned, for shooters in search of a well-balanced different, the 62-grain Stable Copper REX bridges the hole between the light-weight versatility of the M855 and the specialised precision of the 77-grain OTM.
Though lighter than the 77-grain OTM, the REX achieves comparable accuracy and terminal impact, making it a sensible selection throughout varied mission necessities.
Why Change to the 62-Grain 5.56 REX?
In case you count on extra out of your ammunition, the HOP Munitions 62-grain Stable Copper REX is the reply.
Unmatched Stopping Energy
In contrast to conventional steel-core or hollow-point rounds, the REX is designed to ship devastating terminal efficiency. Upon affect, its stable copper building ensures constant enlargement, maximizing power switch to the goal. Whether or not for looking, dwelling protection, or responsibility use, this spherical gives absolute confidence in its stopping energy.
Accuracy
With a ballistic coefficient of .300, the 62-grain REX gives superior stability and flat-shooting efficiency—even in wind or at prolonged ranges. It cuts via obstacles and maintains accuracy.
Environmentally Pleasant and Mild Barrier Penetration
The REX’s stable copper construct eliminates lead publicity and enhances sturdiness. It could penetrate gentle obstacles akin to auto glass, plywood, and sheet metallic with out sacrificing structural integrity, making certain constant outcomes.
Mission-Prepared Versatility
Whether or not you’re a predator hunter working in open fields or a legislation enforcement skilled partaking on responsibility, the 62-grain stable copper REX is as much as the duty.
Remaining Ideas
The 62-grain REX surpasses legacy hundreds just like the M855 and Mk318 in power switch and terminal efficiency whereas delivering accuracy similar to heavier 77-grain OTM—all in a lighter, sooner package deal.
In case you’re in search of ammo that hits more durable, shoots flatter, and performs flawlessly—the HOP Munitions 62-grain REX is the reply.
Cease settling for “adequate.”
