Winchester 125gr Open Tip 300 Blackout Ammo, 20rd – USA300BLK

Shoots 3-4 MOA with a red-dot/irons through a few average 16" ARs. It's not match ammo, so I really can't complain. It's cheap and plentiful ammo that is perfect for plinking.

On average 2 per box wont fire due to primer seated to low. I bought a case. When practicing on the range with my ar its a pain to cycle a misfire. I switched to Hornaday

I noticed a lot of people giving a bad review, but I have never had a single problem with Winchester White Box. As a Law Enforcement Instructor, I use a lot of Winchester ammo at instructor schools and training. I'm sure there may be an occasional issue, but I have personally never had one myself.

Bought 5 boxes online. Received today, majority of the rounds are defective, necks being cracked or damaged. Poor manufacturing.

I purchased 120 rounds for a new build. And I have had nothing but failure to feed after failure to feed . I have used different mags and had my gun cleaned and lubed by my local gunsmith . Other ammo I ha w used it performed flawlessly only with this ammo.

I have never purchased ammo in such ruff shape. Always considered Winchester very reliable but now having second thoughts.

Great bulk ammo that your wallet doesn't mind works great for target and training ammo, and even self defense if needed.

I tested four different brands to target shoot from 100 to 400 yards with a 16'' AR. This M855 consistently had the best groups. So this is what I'm going to keep using.

Good quality ammunition, I've tested the white box stuff in multiple rifles and so far I've been pretty satisfied. Any malfunctions I've had (though few in number) were probably due the specifics of the rifle I was using. Though further testing would probably be required. For the most part, the bullet comes out the business end just fine.

I am completely satisfied with my purchase, keep up the good work. I WILL CONTINUE TO PURCHASE YOUR PRODUCTS.

Purchased a 200 round box of 5.56 and found issues with the quality. Bent brass, cracked brass ect. looked on the web site only to see that quality conttrol doesnt exist. I thought my issue was isolated but I see it is not. Sad to see a old established brand known for quality and reliability loose sight of certain standards.

I've tried lots of ammo and this shoots the best. I wish it was easier to find and I wish there were other grain wieghts.

iv always had great luck with winchester ammo. its usually loaded hotter than the green or red box stuff. i love the specialty stuff like the turkey ammo and silver tip hand gun 10mm. in fact most of my mags are filled with win factory ammo right now.

Low quality failure to feed and fire. Read the reviews this batch is not worth the money in automatic feeding rifles.

I love these rounds and are looking for more! My Remington BDL Varmint rifle loves these rounds. Consistently puts 5 rounds into a penny size grouping. Please let me know where I can buy more!

This is my go-to 5.56 ammo. It’s cheap, goes bang every time, and the velocity is actually quite consistently higher and a consistent speed than other 55gr 5.56 that I’ve found. I use this for my ARs and it’s great quality for a low price. It’s not precision ammo, but it is accurate enough to have a great time having shooting competitions with friends, and definitely accurate enough for training.

7 out of 20 won't fit in the gun, it's like it's expanded near the head.Of the remaining 13, 4 are snug.only 9 dropped in like they should...

I used this ammo and on the second round the jacket came off inside my suppressor. The quality is poor on this ammunition. I do not recommend it for suppressor use at all.

Had several rounds with issues of failure to feed due to brass and also failure to fire. Probably will not buy Winchester rounds.

Okay I guess, as of now I haven’t had the time to fire any of them…as soon as my project is finished, then I will make sure my new build will go bang bang!
