Customer Reviews

  • Me said:

    Good overall performance and good price

  • NW said:

    Great experience. Hard to find ammo at good prices. Customer service was excellent with an issue we had to resolve with my order. Top shelf all the way around.

  • Tom said:

    Shoots excellent

  • Alex said:

    Those rounds go off every time tearing through things

  • Thomas said:

    Ran this ammo thru my Ruger AR with a Banish suppressor on, and everyone was amazed at how quiet it was, and when my target came back in, how accurate. Great ammo, would buy again.

  • Cam said:

    Ammo was cheap and works as designed

  • Matthew said:

    Ammo was inexpensive and dependable. Shipping was on time. Would definitely recommend.

  • Chris said:

    I bought 500 rounds of the 556 FMJ out of the first few boxes (60 rounds) 11 have failed to fire. Firing pin struck the bullet but no boom. Will not be purchasing again.

  • 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.

  • BonzoDRmc said:

  • 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!!

  • Def said:

    This stuff is cheap, and I value that. The last 4 boxes I bought are super dirty and not polished like it is 40 year old military surplus. You can see the annealing, and it looks like it came out of an ammo can 40 yrs ago . The consistency is all over the place and I wonder why.

  • 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

  • Greg said:

    Exactly what I needed. Now I just have to learn how to fire the weapon.

  • Dave said:

    Great ammo for coyotes Local stores don't carry 40 grain anymore I will buy from your company for other ammo when my stocks get low

  • 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 ,.

  • Jt said:

    Will buy again.

  • Rick said:

    These rounds worked just fine.

  • Joe said:

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

  • Larry said:

    good ammo at an excellent price

  • 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 .

  • Shad said:

    Great Ammo; Pricey

  • J bone said:

    Same ammo as all the rest, most I've ever paid .

  • anthgrge said:

    Subtle and accurate aim and shot , great point of contact at the target. Very effective at the range.

  • Branded said:

    Very well made and an excellent value. Will definitely buy again.

  • Oleg said:

  • BMB said:

    You can not go wrong with this ammo.

  • Rickles said:

    Good price for good ammo.

  • Gunny said:

    Will purchase more ammo from these guys. Thumbs up.

  • Paul said:

    It shoots 1&1/4 in groups. Someone a little younger should make it a little smaller

  • Dano said:

    Keep up the good work thanks

  • Blackfott said:

    Good rounds. Worked well for shooting. No jams . Good price. Will buy again.

  • Buddy said:

    Great product at a great price.

  • Brad said:

    I'll keep re-buying PMC 223 until I have a reason not to. They're priced nice and always work in my different rifles.

  • Jerryaa51 said:

    I was very please with that courtesy and knowledge the people that I have talked to.

  • Kim said:

    Good stuff

  • Joel said:

    This round was very consistent, very clean. I don't think you can do better for price in a brass cased round. Shooting in a Daniel Defense m4v11 they were flawless. Definitely ordering more.

  • Shooter magavin said:

    Have bought this ammo a couple of time and could not be happier

  • ammosmurff said:

    I've shot PMC ammo for years on the range, for .223, .45acp & 9mm, never had a misfire or failure to feed on any of my guns. Korean ammo is the only foreign ammo I'll buy!

  • J A said:

    I have not shot any of this ammo as of yet because it is down the line in my rotation. But I was comfortable purchasing PMC ammo as I've never had any bad ammo from the company. The price was right at the time so it was a good buy for me. I look forward to purchasing ammo from your site again, thank you...

  • Dave said:

    Very good ammo for the money! Reliable and accurate. Can't ask for anything more than that.

  • dkmatthews said:

    There's no doubting the quality of PMC Bronze. It's super reliable in every firearm. Thanks for a good deal on the case of ammo.

  • chris said:

    I have a remington Model 700sps varmint 223. with a bull barrel, n added a bipod, and a Barska 4-14 x 40 scope. i picked up a fiew boxes of the pmc bronze boat tail ammo in 55 grain simply because they wer only 7.25 for a box of 20. i was realy surprised on how consistant they wer. i placed 18 outa 20 rounds in a 3 inch circle at 150 yds. with a slight breeze. over all im realy pleased with this product, and will continue to use, an recommend this ammo.
