First Impressions of Winchester 5.56x45mm NATO 62 grain Green Tipped – 1 out of 7 models
In the realm of 5.56x45mm ammunition, the Winchester 5.56x45mm NATO 62 grain Green Tipped – 1 out of 7 models stands as a widely recognized option, often associated with its military designation, M855. Winchester, a name synonymous with American ammunition manufacturing, offers this load with its distinctive green tip, signifying the inclusion of a steel penetrator designed to enhance barrier penetration. This ammunition is designed for AR-15 platforms, and the promise of consistent accuracy and a robust shellcase immediately piqued my interest.
I’ve been searching for a reliable and readily available 5.56 NATO round for training and potential defensive applications. Availability, consistent performance, and acceptable accuracy are my primary concerns. While there are certainly “match grade” options available, they come at a premium and are often harder to find in bulk. I wanted something more practical, yet reliable.
The ammunition arrived in a standard cardboard box, neatly packaged in individual cardboard sleeves, which is typical for bulk ammo purchases. Initial impressions were positive; the rounds appeared clean and well-manufactured, with a consistent green tip coloring. The brass casings looked polished, suggesting good quality control.
Compared to other common 5.56 NATO loads like the Federal American Eagle 55-grain FMJ or PMC Bronze 55-grain FMJ, the Winchester 62-grain green tip offered a potentially higher ballistic coefficient and enhanced penetration capabilities. I ultimately chose the Winchester offering because of its reputation for reliability in AR-15 platforms and the perceived increase in terminal performance from the heavier, steel-core projectile. The price point was also a factor, as I was looking for a balance between quality and affordability.
My first impression was cautiously optimistic. The overall appearance and reputation of Winchester instilled a degree of confidence, but the true test would be its performance on the range. Would it live up to its promise of consistent accuracy and reliable feeding in my AR-15?
Real-World Testing: Putting Winchester 5.56x45mm NATO 62 grain Green Tipped – 1 out of 7 models to the Test
First Use Experience
I tested the Winchester 5.56x45mm NATO 62 grain Green Tipped – 1 out of 7 models primarily at an outdoor shooting range, under relatively mild weather conditions. The temperature hovered around 70 degrees Fahrenheit with a slight breeze. I used a standard AR-15 platform with a 16-inch barrel and a 1:7 twist rate.
The ammunition performed admirably during the initial testing phase. There were no failures to feed, fire, or eject across several magazines. Recoil felt consistent, and the muzzle flash was within acceptable limits for a 5.56 NATO round.
One initial surprise was the slightly louder report compared to standard 55-grain FMJ rounds I’ve used in the past. This could be attributed to the slightly higher powder charge required to propel the heavier 62-grain projectile. Other than the increased volume, the first range trip was uneventful.
Extended Use & Reliability
After several months and approximately 1000 rounds of usage, the Winchester 5.56x45mm NATO 62 grain Green Tipped – 1 out of 7 models continues to perform reliably. I have experienced zero malfunctions across multiple range sessions and training exercises. The ammunition has been stored in a cool, dry environment, and there are no signs of corrosion or degradation.
Durability has been excellent. The brass casings appear to hold up well, even after being reloaded (although I don’t typically reload 5.56 NATO). The green paint on the projectile tips remains intact, showing minimal wear.
Maintenance is simple; after each range session, I clean my AR-15 thoroughly, and the Winchester ammunition leaves a typical amount of residue. Cleaning is straightforward, with no excessive carbon buildup compared to other brands.
Compared to my previous experience with surplus 5.56 ammunition, the Winchester offering represents a significant improvement in consistency and reliability. The peace of mind knowing that each round will perform as expected is invaluable, especially in a defensive scenario. It noticeably outperforms some of the cheaper, imported brands I’ve tried, justifying the slightly higher price point.
