Customer Reviews

  • Freakazoid said:

    This ammo is very consistent. Bench firing my Sako .223 I can put three consecutive rounds in a nickle at 100 yds. Love this ammo!

  • Al said:

    As good as Federal and a lot less expensive.......Federal is supposed to be the Cadilac of ammo.....well, PMC is equal if not as good or even better.....I am a user from now on.

    CANT GO WRONG WITH THIS AMMO

  • ammo said:

    remington did it again with another great ammo and ammo.com low price you can't bet it.

  • 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.

  • Mike O said:

    Shot this on my high end Geissele rifle and very, very happy with it ... target practice

  • Karl said:

    For the price I'd say a good purchase. Out of 200 rounds maybe around 15-20 rounds that I'd assume had bad primers and didn't fire.

  • BWalter82 said:

    This ammo is clean firing, accurate to 2 moa, and I never had a problem in any of my rifles; probably the "best bang" for the buck out there!

  • Freddy said:

    Better then I excepted. Quick delivery, at a great price. Not one fault. Will be using again in the future. Keep up the good work guys.

  • Richard said:

    No problems shooting from any of my ARs

  • Hank said:

    Fired 200 rounds and the ammo performed so far performed well.

  • dan from ohio said:

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

  • Alex said:

    Those rounds go off every time tearing through things

  • 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.

  • 223/556 said:

    Price was low, came in good packaging, ammo performed as it should cycling and firing, and the order arrived on time I am very impressed with this product

  • Chris said:

    Arrived pretty quick, packaged up pretty good, I haven't opened them to use any yet just stocking ammo.

  • Joey said:

    No issues!

  • Matthew said:

    The Ammo is great, but the one hitch in my "Giddy-up" is: The ammo on the website reads "FMJ-BT", but what showed up at my door was regular FMJ. I'll still shoot it, but I'll be wary, before I order from here.
