Customer Reviews

  • Ken said:

    I've been using PMC ammo for about 40 years. NEVER had a problem with it and AMMO.COM has good prices too.

  • SAL said:

    LOVE THIS PLACE FOR MY AMMO. I AM ABLE TO DONATE TO WOUNDED WORRIER AND GET AMMO CAN'T BEAT IT.

  • Brian said:

    My son and I have shot thousands of rounds of the PMC with no complaints whatsoever. And you won't find a better deal on 62 gr 556 bulk ammo anywhere

  • Shooter said:

    The ammo performed awesome.

  • Bone Crusher said:

    Shoots straight, flying fast.

  • T-bag said:

    For the price and quality, never thought I'd be using green tips as target rounds. My AR hasn't jammed up yet after 100 rounds or so, which is impressive. My AR is very picky on ammo, usually can't get 30 rounds out without a couple jams. But this stuff runs like butter through my AR, with some impressive penetration to boot.

  • Mick said:

    All ammo went down range with consistent velocity and tight groupings. Previously purchased ammo from another party had poorly seated primers, this jamming my fire arm.

  • olbull said:

    same as title

  • john said:

    good product / good price

  • Carl said:

  • AZ SHOTGUN said:

    Great ammo for the price.

  • Nate said:

    The ammo itself LOOKS beautiful compared to Lake City penetrators but I have not shot it yet so I can't comment on that. I paid more per round, but that is just the market, not Ammo.com.

  • Bigthiss said:

    Great ammunition for the price. I used to buy the federal loose bulk ammo in 500 and 1000 but there were always at least 10-20 that were either faulty loads or misfired. This ammo is hands down the best for the price that I have purchased and shot. Highly recommend!!
