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.

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.

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.

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.

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 ,.

It's Hornady Black. Goes down range well, gives decent groups at 50 & 100 Yards through a Hellion. It's not Match grade but it is consistent for my usage. Good prices and quick shipping is always a bonus too! Thanks Ammo.com

JV said:
As the title states it fired every time I pulled the trigger and I was satisfied with the grouping at 50 yards with just a Trijicon MRO. For range training ammo I wouldn't hesitate to order it again. Plus the shipping and order processing was very fast! All good.
David said:
Performs well
Joe said:
As far as the look and the function of the ammo I’m really pleased with it. The price met or was cheaper than competitors. They were packaged well and clean. They also fired great out of my AR. The thing that stood out the most was the fact that I made my purchase on July 3rd around noon and I received the ammo on July 4th before noon. I was so surprised! I will definitely be ordering here in the future.
