.223 / 5.56

223 Remington ammunition and 5.56x45 NATO rounds are among the popular cartridges for American civilian shooters. Both are light-weight cartridges with relatively low recoil and a ton of muzzle velocity, making them easy on the rifleman to fire consistently and quickly.

223 ammunition is the most popular rifle caliber in terms of rounds sold in the United States today. Commonly paired with the AR-15 Armalite rifle, these rounds a capable for defense but most commonly used by recreational sport shooters who like the flexibility the very fast, light-weight bullet provides. You can expect muzzle velocities in the neighborhood of 3,000 feet per second with most rounds along with a muzzle energy rating that's around 1,300 foot pounds.

Look for a wide assortment of in-stock 223 ammo along with 5.56 with bullet weights primarily in either 55-grain or 62-grain. We carry both bulk full metal jacket loaded rounds, like these from PMC and hollow point bullets that are better suited for hunting or competition shooting, like these match-grade rounds from Fiocchi. All of our 223 ammo for sale is in-stock with fast shipping.

    I am very impressed with the responsiveness from "Ammo to Go" and appreciate how quick I received my order. Additionally, the prices are great as well as is the quality and selection of the ammo. I will highly-recommend you to others I know, as an awesome source to buy ammo. Thanks so much for everything!!

    Of the steel cased foreign made ammo the only brand I have ever had problems with has been Tula in 7.62X39. Yep, it goes bang but many lots are so obviously inconsistently loaded that you can HEAR the difference between different rounds.....and of course your groupings expand greatly. The stuff that Century has a hand in importing called Red Army Standard is merely Tula repackaged so..... In .223 I have heard generally good reports. Strange but from several different people it seems to be a good range/practice round. I personally have had good luck with Tula in pistol calibers, specifically 9mm.....my Glock 19 and 26 gobble em up and they group decently and of course they are inexpensive rounds to shoot. I feel that a lot of the bad reviews of any steel cased ammo is similar to old reviews of Glocks when they were first introduced. As late as 1989 I fell into that category when one Christmas the wife gifted me an early Gen2 Glock 19.....I put on the usual act of course with the "oh, honey, this is so wonderful, Ive heard so much about these guns"....yadda yadda yadda. The gun sat in my safe mostly untouched while the BS stories about the guns being invisible to airport X-ray went through the media and common talk........that started me taking another look as there is a LOT of metal in a Glock which would of course be very visible on any xray...so I started practicing and running that old 19 and started a passionate affair with the gun that was exhibited by the usual buying of extended this and thats and installing trigger upgrades.....the gamut. I still have and use that old Glock 19, it still runs like a swiss watch and with its latest add on, a trigger pack made perfect by Johnny Glock......well, I had become pretty good with that old Glock and two others but I got even better by the incredible work Johnny Glock can do with a trigger group. Anyway, that old "plastic gun POS" bull crap is now almost forgotten but the "all steel cased ammo is horribly innacurate, lots of failures to fire and function, wears out your chamber and barrel"......all of it largely BS pure and simple by people that still believe that the 1911 is by far the finest gun ever made by Gods hands themselves and not the obsolete overweight limited capacity gun of yore that it actually is. Try the stuff and decide yourself. My guess is that you will have good success simply by being able to afford to practice more.
