  • Alan said:

    Product was shiped in a timely mannner was well packaged and performed perfectly

  • Carl said:

    Will be ordering more I am very satisfied with the delivery and price ammo shoots good

  • 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!!

  • 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 .

  • Becca said:

    Ok

  • Sike said:

    For relatively cheap ammo Works fairly well only had 1 misfire out of about 200 just had a little too much lacquer on it

  • donald said:

    good ammo good price fast shipping will buy more and tell my friends..i do recommend

  • Dr. O. said:

    This ammo was a great value. And performed well. Not a single jam. Very consistent

  • TedG said:

    Fired about 100 rounds. No misfeeds, no duds, no significant accuracy loss over green-tips at 100yrds. I did notice that the spent casings actually eject a little differently (more to the rear and in a tighter grouping). This is actually nice for me because, when I fire federals, about 1/2 of the brass flies out the window of my shooting hut while the Wolf "brass" piles up in a neat little spot next to me on the inside of the hut. The price is right - highly recommended for plinking!

  • myob said:

    good ammo

  • Rick said:

    Price was right, delivery was quick, Fed and ejected with no problems.

  • Jimbillyjoebob said:

    You have to keep your AR clean no matter what ammo you feed it. I would not use this ammo for hunting if I had better available, but if you're going to be humming through 300+ rounds on an afternoon, it's hard to beat. Very rare misfeeds.

  • RONALD said:

    No surprise here but the price per round shows as 63.8 cents. With shipping and sales tax, that easily went to about 85 cents. I did receive it in a timely fashion and it was well-padded in a cardboard box but would have preferred different packing from the factory. My error. A range pack means loose rounds inside a box. The ammo itself is so-so for its intended purpose. I also purchased Belom 7.62x39 (no longer available here) and cannot address ammo quality yet, but the factory packaging (20 rounds per PLASTIC case) was phenomenal.

  • 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

  • Snake said:

    Great ammo! Shoots and cycles perfect. Will defiantly buy more.

  • lroberts103 said:

    Great company to work with. Fast shipping great price

  • Michael said:

    This 5.56 ammo was just what my AR needed.
