Understanding the M855 "Green Tip" Designation

The "Green Tip" designation on this Winchester ammunition refers to the M855 standard for 5.56x45mm NATO rounds. Originating from military specifications, the M855 cartridge is characterized by its 62-grain bullet which incorporates a steel penetrator tip, covered by a lead core and a full metal jacket. This unique construction provides enhanced penetration capabilities, particularly against light barriers, compared to traditional lead-core FMJ rounds. The green paint on the projectile tip is a military color code used to easily identify these rounds.

While developed for military applications, the M855's robust design makes it an excellent choice for civilian range use. Its stable flight characteristics and consistent ballistic performance make it ideal for:

• Zeroing firearms: Ensuring your optics and iron sights are perfectly calibrated.
• Target practice: Engaging paper, steel, or reactive targets with reliable impact.
• Skill drills: Practicing rapid fire, transitions, and marksmanship fundamentals.

The M855's widespread use and adherence to NATO standards mean that firearms chambered in 5.56x45mm NATO are typically optimized to cycle this ammunition flawlessly, offering peace of mind during critical training scenarios.

The Power and Versatility of 5.56x45mm NATO Caliber

The 5.56x45mm NATO cartridge is one of the most popular and widely adopted rifle calibers in the world, primarily due to its association with the ubiquitous AR-15 platform and other modern sporting rifles. This caliber strikes an excellent balance between manageable recoil, flat trajectory, and sufficient energy for a variety of applications.

Key advantages of the 5.56x45mm NATO caliber for shooters include:

• Widespread Compatibility: Almost all AR-15 type rifles are chambered in 5.56x45mm NATO (or .223 Wylde), ensuring broad compatibility.
• Excellent Ballistics: Delivers a high muzzle velocity, resulting in a relatively flat trajectory over common shooting distances, simplifying aiming.
• Manageable Recoil: The relatively light recoil impulse allows for faster follow-up shots and extended shooting sessions without fatigue.
• Abundant Availability: As a military-standard cartridge, 5.56x45mm NATO ammunition is widely produced and readily available.

Winchester's USA M855 further enhances these inherent benefits by providing a consistent and high-quality load that maximizes the potential of your 5.56x45mm NATO firearm.

Full Metal Jacket (FMJ): Ideal for Consistent Training

The Full Metal Jacket (FMJ) bullet type is the cornerstone of effective and economical training ammunition. An FMJ bullet consists of a lead core completely encased in a harder metal jacket, typically copper or a copper alloy. This design offers several distinct advantages for range use:

• No Expansion: Unlike hunting or self-defense rounds designed to expand upon impact, FMJ bullets maintain their shape, ensuring predictable penetration and consistent performance on targets. This is crucial for accurate trajectory and preventing over-penetration on range backstops.
• Positive Functioning: The smooth, consistent profile of an FMJ bullet ensures reliable feeding and ejection in semi-automatic firearms, minimizing stoppages and maximizing training efficiency.
• Good Accuracy: While not match-grade, the consistent manufacturing process of Winchester's FMJ bullets contributes to good inherent accuracy, allowing shooters to hone their skills effectively.
• No Barrel Leading: The full metal jacket prevents direct contact between the softer lead core and the rifle's bore, significantly reducing lead fouling and making cleaning easier. This contributes to barrel longevity and consistent accuracy over time.

For high-volume practice, the FMJ design is superior, offering the reliability and clean performance that serious shooters demand.

Key Performance Specifications Explained

Understanding the technical specifications of your ammunition helps in appreciating its performance characteristics. For the Winchester USA M855 Green Tip 5.56x45mm NATO 62 gr FMJ, these include:

• Muzzle Velocity: 3060 fps (feet per second)

  This high velocity means the bullet travels very quickly, resulting in a flatter trajectory over longer distances. For shooters, this translates to less bullet drop and easier aiming, especially at varying ranges. It also contributes to the bullet's terminal performance on targets.

• Muzzle Energy: 1289 ft lbs (foot-pounds)

  Muzzle energy represents the kinetic energy of the bullet as it leaves the barrel. A higher muzzle energy indicates greater stopping power and more significant impact on the target. While primarily a training round, this energy level is robust for its class, ensuring reactive targets are engaged effectively and paper targets show clear impacts.

• Bullet Weight: 62 gr (grains)

  The 62-grain weight is a standard for M855 rounds. It strikes an optimal balance for the 5.56x45mm NATO cartridge, offering good ballistic stability and energy retention without excessive recoil. This weight is widely compatible with twist rates found in most AR-15 barrels (typically 1:7 or 1:9).

• Rounds Per Box: 200

  This generous count makes it ideal for extended range sessions or for stocking up. It reduces the need for frequent reordering and allows for more uninterrupted training time.

• Boxes Per Case: 4

  Purchasing by the case (800 rounds total) offers even greater value and convenience for high-volume shooters and ensures you have a substantial supply on hand.

Optimizing Your Range Sessions with Bulk Ammunition

Purchasing ammunition in bulk, like the 200-round boxes or 800-round cases of Winchester USA M855 Green Tip, is a smart strategy for any serious shooter. Not only does it typically offer a better per-round cost, but it also ensures you're always prepared for your next range visit. Having an ample supply of consistent ammunition allows for:

• Uninterrupted Training: No need to stop and open multiple smaller boxes.
• Cost Savings: Bulk pricing usually leads to significant savings over time.
• Consistent Practice: Using the same type of ammunition consistently helps you understand your firearm's performance and improve your personal shooting mechanics.
• Ready Availability: When you shop at DEGuns, you can count on reliable stock and quick delivery of these essential training rounds.

Common Questions Answered about 5.56x45mm M855 Ammo

Here are answers to frequently asked questions about Winchester USA M855 Green Tip ammunition:

• Is M855 safe for my AR-15?

  Yes, absolutely. M855 ammunition is specifically designed to meet NATO specifications for 5.56x45mm firearms, including the vast majority of AR-15 platforms. Ensure your rifle is chambered for 5.56x45mm NATO or .223 Wylde for optimal compatibility. Rifles chambered only for .223 Remington might experience higher pressures, so always check your firearm's markings.

• What's the best use case for M855 Green Tip?

  The primary and most recommended use for Winchester USA M855 Green Tip is high-volume target shooting, tactical training, and general range practice. Its consistent performance, reliability, and economical nature make it perfect for honing marksmanship skills, practicing drills, and ensuring your firearm functions optimally.

• How does Winchester M855 compare to other training rounds?

  Winchester M855 stands out due to its adherence to military specifications, incorporating the 62-grain bullet with a steel penetrator core. While many training rounds are 55-grain FMJ (like M193), the M855 offers slightly different ballistic characteristics, often preferred by those wanting to train with a round closer to certain military-spec loads. Winchester's reputation for quality also ensures superior consistency compared to some generic bulk ammunition.

• Why choose brass casing over steel or aluminum?

  Brass casings are highly preferred for rifle ammunition due to their superior ductility, which allows for reliable expansion upon firing to seal the chamber and then contract for smooth extraction. They also resist corrosion better than steel and are much stronger and more durable than aluminum. For those who reload, brass casings are often reusable multiple times.

• What accuracy can I expect from this ammunition?

  Winchester USA M855 is designed for good accuracy suitable for training and general range use. While not match-grade ammunition intended for sub-MOA precision at extreme distances, it is more than capable of delivering consistent groups for effective target practice and skill development at typical shooting ranges. Expect reliable performance and the ability to maintain tight groups with consistent technique.

The Winchester USA M855 Green Tip 5.56x45mm NATO 62 gr Full Metal Jacket ammunition is more than just rounds; it's an investment in your shooting proficiency and the longevity of your firearm.
