History of Winchester 5.56x45 Ammo

Why Buy Winchester 5.56 Ammo?

Since 1886, the Winchester Repeating Arms Company has been at the forefront of innovation for firearms and ammunition technology. This legacy is reflected in the multiple lines of Winchester 5.56 ammo that are second to none in the industry.

The AR-15 is undoubtedly America’s favorite semi-auto sporting rifle, and there’s no better way to keep your AR happy than by feeding it a steady diet of Winchester 5.56 ammo 1000 rounds bulk packs. The 5.56x45mm NATO has become the benchmark for target shooting and varmint hunting, and Winchester 5.56 is one of the top options when you need long-range accuracy combined with a combat effective round.

Winchester 5.56 Match ammo is some of the best in the business, available in 77 grain bullets which is the heaviest and longest bullet an AR-15 can handle in its magazine. For any 3-gun or action shooting event, this is perhaps the best 5.56mm match ammo available at the price point Winchester offers.

For personal defense, Winchester 5.56 Defender ammo loaded with a 64 gr bonded solid base bullet is the best for any home defense situation.

However, for the most common and affordable Winchester 5.56 NATO you should look to the M193 and M855 varieties. Winchester 5.56 M193 ammo mimics the original NATO load for the M16/AR-15. Firing a 55-grain full metal jacket at 3180 fps, M193 makes an awesome plinking and target shooting round.

But if you want current NATO standard mil-spec ammo, then you need to grab a case of Winchester 5.56 Green Tip M855. Complete with a mild steel core penetrator, 62 grain Winchester 5.56 Green Tip ammo is as close as you can get to military issue armor penetrating (AP) rounds. These bullets are marked with green paint on the tip for easy identification.

With so many different lines of ammo, it’s no wonder why Winchester 5.56 ammo is highly regarded by military, law enforcement, and civilians alike.

How can you Save Money on Winchester 5.56 Ammo?

One of the best things about 5.56 NATO is that it is inexpensive. This means you can shoot a lot without breaking the bank. However, if you want to save even more money you can buy bulk 5.56 ammo. When you’re looking to pick up Winchester 5.56 ammo 1000 rounds at a time, you’ll get some of the best cost savings per round possible.

Buying from our bulk 5.56 makes sure that you always have enough ammo to get to the range regardless of market conditions.

Ammo shortages are irrelevant to you when you load up on bulk Winchester 5.56 green tip ammo or M193, because you will have stocked up on some of the most affordable brass cased ammo we have in stock. Your friends will be sitting at home playing Call of Duty while you’re loading up your range back with the bulk Winchester 5.56 you so smartly bought in advance.

    Will buy again.

  • Rick said:

    These rounds worked just fine.

  • Steven said:

    The Ammo performed great. Consistent groups and accuracy. I experienced zero failures in the 300 rounds I fired. I used the ammo in a 1/9 twist barrel and Zerroed and Primary Arms LPVO in just 12 rounds. Once zeroed my shots stayed withing the 300 meter silhouette center mass circle. I'm verry impresssd. I did know what to expect since I always use the higher grain green tip from winchester. Many say you need a 1/12 twist barrel to get good performance from this ammo; I disagree.

  • Fiftysum said:

    I just bought a Colt LE6920 5.65 caliber. The closest thing I ever shot was my M16 when I was in the Army during the Vietnam era -- a long time ago. So my review is not based on a comparison with any other ammo brand in this caliber. I bought Winchester because it is a known brand, is labeled for target use, and I feel it was available for a good price here on Ammo.com. I know there are some premium brands, which I will try eventually, and there are lots of brands I never heard of. Some of them may be good, I just don't know anything about them yet. I'm giving the Winchester 5.56 target ammo five stars in each category because my shots were consistently within one inch of the bullseye at 25 and 50 yards. That I hit the target at all at 100 yards I will count as okay because I didn't have a scope and I could just barely make out the 100-yard target with my not-so-good-as-when-I-was-20 eyesight. I qualified "sharpshooter" when I was in the Army, having missed "expert" by one shot. It makes me happy that this Colt M4 is as accurate, if not more so, than my Army M-16. Good ammo should give consistent results. This Winchester target brand delivers for me.

    Man this ammo can in, in a matter of days nice quality

  • Joe said:

    Really good on the range. haven't had a problem yet

  • RONALD said:

    No surprise here but the price per round shows as 63.8 cents. With shipping and sales tax, that easily went to about 85 cents. I did receive it in a timely fashion and it was well-padded in a cardboard box but would have preferred different packing from the factory. My error. A range pack means loose rounds inside a box. The ammo itself is so-so for its intended purpose. I also purchased Belom 7.62x39 (no longer available here) and cannot address ammo quality yet, but the factory packaging (20 rounds per PLASTIC case) was phenomenal.
