Customer Reviews

  • SH in TX said:

    This ammo has proven to be the most accurate I've found out of a Remy 700 HB with a 1:12 twist. Had almost given up on accuracy with this rifle, but this load yielded 0.7 MOA (100 yds, calm day, off support).

  • USA GUNNER said:

    Glad to have found this website customer service has been great and product just as described.

  • 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.
