Customer Reviews

  • Ranger5688 said:

    Bullet strength and bullet placement are key factors,. I wouldn’t recommend all 223 for big buck deer,. Only a few will do the trick ,. It takes a powerful vital hit to bring a buck down,. The penetration and shock wave is what’s needed to take the game down ,. Choose your caliber wisely ,.

  • Pogo said:

    Consistent sub MOA groups with a Fulton Armory AR-15 A2, SS match barrel 1:9 twist. Compared to similar match loads by Black Hills, Remington and Hornady; factor of 2 improvement on accuracy with this Federal ammo. Ammo.com get more of this into stock!

  • USMC1 said:

    I have tried a number of rounds from flat base hollow point to ballistic tip's but I was not satisfied with the results. So, I tried the 69 grain BTHP match, I was very pleased with the results, much more consistent, however purchasing massed produced ammo for accuracy is not the way to go. If you shoot a lot, reloading your own ammo is the best way to ensure that every round is the same. I feel the value of the ammo is about average in cost. What I paid for the 40 rounds from ammo net including shipping I could buy the same at a local store, so not really a savings.

  • dan from ohio said:

    looked for a great deal and found it here, the ammo was great and I am very pleased

  • Cody said:

    Best 62 gr round Ive used. I shoot a .223 Wylde barrel on a AR -15 used for matches. These perform close to as well as hand loads made for the rifle. I would use them for more than practicing anytime

  • primerak said:

    I actually like these rounds better than the winchester boxes. seems to fly flatter.

  • Alex said:

    Those rounds go off every time tearing through things

  • THL said:

    Took it out in my tavor, with a 14x primary arms scope, shoots about 2 MOA off of a bench in quick fire. Not too shabby for a HD OTM round rather than the match BTHP rounds

  • Joe said:

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

  • Rico said:

    This is a quality bullet

  • Mad Dawg said:

    Service and shipping is top-rate with these folks.

  • Head hunter said:

    Shoots amazing accurate and plenty of knock down power for plucking down rodents such as ground hogs . You can reach out and touch something with accuracy and confidence .

  • Bru said:

    It's Hornady Black. Goes down range well, gives decent groups at 50 & 100 Yards through a Hellion. It's not Match grade but it is consistent for my usage. Good prices and quick shipping is always a bonus too! Thanks Ammo.com
