Great ordering process and phone check for delivery, ammunition worked well. I had no jams or mis-feeds during range Clean shots on target at 100 yards with my AR. Cleaning was easy with minimum carbon buildup.

I bought 1k rounds of steel cased .223 and it arrived in less than 48 hours. I know you aren’t “supposed” to shoot steel cased out of an ar15, but after about 500 rounds I’ve experienced zero problems. It’s hard to beat 35 cents per round.

I ordered this ammo on a Monday and it was at my door on Friday! Considering that it had to be shipped four states away that is FAST shipping. I also like the fact that Ammo.com donates a portion of every sale to pro gun institutions. This is now my number one "go to" source for ammo.

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.

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.

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

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!!

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 ,.
