I've used Winchester rounds in other calibers and never been disappointed by them, and I can say the same for these 5.56 rounds. Excellent training rounds, good pricing, and I've had no issues with the first 450 rounds I've used so far.

The rounds were dirty, with some having excess powder or some kind of processing oil/grease on them. A few boxes had 18/19 rounds in them. Worked well in my rifle after 500 rounds so far and were a good price.

So in regards to this specific order, they did an amazing job as always. This company tends to ship things extremely fast, to the point I’m shocked at how they get it done that fast! What I do have to mention is how they did me a really huge favor without me, even knowing about it. I’m new to guns. So I’ve made a couple mistakes purchasing ammo. I purchased some steel core bullets, only to find out I could not shoot them at my range. Then just recently, and this is the order I want to speak about, I did it again. I ordered something called boattail ammo. I realized I couldn’t use that at my range either. So I called and asked to see if there’s any way to change it simply because I just put the order in. She looked and she said they’re pretty fast down there. And then the bad news, she said she wasn’t able to do anything about it. Well, I end up getting my order. Low and behold, she switched it out for the regular FMJ without even telling me. I was so grateful because I didn’t wanna have $1000 worth of ammo I couldn’t use. You guys have great customer service and I really appreciate all the help!

Shoots good, fair price. These didn't appear new, as advertised, due to some discoloration and denting, but they seem perfectly good and serviceable.

I got 800 rounds and I’ve gotten 10 squib rounds out of 3 of the 4 box’s i got. Mind you i have only shot about 100 rounds of the 800 i got.

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.

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.

I bought 500 rounds of the 556 FMJ out of the first few boxes (60 rounds) 11 have failed to fire. Firing pin struck the bullet but no boom. Will not be purchasing again.

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.

Def said:
This stuff is cheap, and I value that. The last 4 boxes I bought are super dirty and not polished like it is 40 year old military surplus. You can see the annealing, and it looks like it came out of an ammo can 40 yrs ago . The consistency is all over the place and I wonder why.

Jack said:
I have always put M193 as offensive/defensive ammo, which is why I purchased it in the first place. I tested 80 rounds at 25, 50, 100, and 300 yards with a Sig M400, it was dead on accurate.
