223 Ammo

223 ammo is a popular choice among AR-15 shooters. With a slightly lower pressure than 5.56 ammo, you can fire 223 rounds in rifles chambered for 223 or 5.56x45. (If your rifle is chambered for 223, you should not shoot 5.56.)

We recommend rifle owners with a 1:12 twist rate shoot 55-grain 223 rounds. For shooters with a 1:8 twist rate barrel, we recommend 62-grain rounds.

So I placed an order that was delivered faster than I expected with product that I am very pleased with. I plan to use this company for my future purchases and will recommend Lucky Gunner to my friends."

I have bought the Lake City reman .45acp and .380-super happy with both rounds. Ok, then I buy several different types of .223/5.56 just to see how they shoot-all were as expected and good stuff. Finally I had to buy more .22longs. Got Federal, Federal Champions and Winchester. I bought 3 bricks of ammo for what I would pay for 2 around here (not counting wasted gas and time). I will order again - Great work folks!"

I did a lot of looking around and this is by far the most user friendly website out there for your ammo needs. Inventory is "real time" so there's no guesswork as to when it will ship. Shipping is fast and the more you buy, the better the overall value! It's a better deal than those "box stores" like Academy, Wal-Mart or Bass Pro AND they have it in stock! I am very happy to have found Lucky Gunner and will continue to tell everyone about it. These guys obviously take pride in what they do and THIS is what customer service should be like. Others could learn something from their model. Thanks again."
