5.56 is what I'm thinking. Shot 30cal but never anything this small.

No offense, but keep dreaming about a 5.56 with any kind of consistency at that range, dude.

if you want to shoot a .223 AR that long of distances, you'll be severely limiting your choices.
A 20" Heavy barrel match grade barrel shooting 75gr, 77gr, 80gr bullets will hit out to 600 not a problem. To hit past that, you'll need a very high quality 24" bull barrel. It can be done, varmint hunters will use a 24" bull to shoot prairie dogs out to 700-800Y. You will also most likely need to use 77gr or 80gr bullets (80 gr bullets are single feed only). Good optics obviously, and a good trigger would also help. |

According to my ballistics calculator, for M193 out of a 1:7 16" barrel, the wind drift at 600 meters for a constant, perpendicular wind (to the shot direction) of 10mph is: 58", which is 4.8333 feet.
Unless you plan on shooting in a windless environment, I suggest you consider a different caliber for this endeavor...or make sure you get a match grade barrel NO less than 20" and shoot only match grade, heavy loads. |

I wouldn't even trust a M193 to consistently hit a 5" circle at 300Y... 77 or 80 gr SMKs are going to be his only choice. |

As everyone else has said the AR15 platform is really cut out for that except maybe in 6.5 grendel. Something that can handle a .308 length cartridge will give you far more options, and won't be cheap. Anything to shoot that well consistently needs to be made of good parts.

Yeah, I updated my post to reflect that my example was based on a poor setup for that distance, and that at the least he should choose a longer barrel and match grade heavy loads. |

In 1998 the U.S. Army Military Police decided that they needed bridge the gap between the basic riflemen and a SRT sniper. So they decided to send about 200 MPs through a precision marksmen school. The training was provided by the U.S. Army Marksmanship Unit (USAMU), and luckily I was one of those selected to attend. Over a three week period we were taught to engaged and hit man-size targets out to 800 meters. This was all accomplished with 20” M16A2 rifles and Ball ammo. There was nothing special about the rifles and the ammo was not match grade. The 5.56x45mm is an inherently accurate and predictable round out to an incredibly long range. The majority of the training that we received was teaching us to trust our rifles. Once an M16A2 has been properly zeroed to the shooter, they can be used to engage targets out to 800 meters. That is why the rear sight aperture rotates up to 8/3. The current version of this training is now a national program provided by the USAMU and it is titled the Squad Designated Marksmanship Course (SDM). The training is conducted utilizing a 14.5” M4 carbine and troops are taught how to engaged and destroy targets out to 600 meters. Today would I engaged a target that far away with my rifle, not likely, but it is nice to know that if I have to engaged targets that far away I will be able to hit them with the first round. http://www.usaac.army.mil/amu/training/sdm.asp |

Man size target, I'm sure a M16A2 w/ ball ammo would work fine. For varmint, target shooting, high power competition, 75/77/80gr match is the standard. |

Take a look at the rifle D&L Sports used to put 20 rds in a 20 inch circle in 20 seconds at 1,000 yds.
I'd float a 24" Krieger 1:7 and load 77 gr SMKs. |

The AMU uses National Match M-16A2's for 1000yd competitions. I know they were experimenting with the 90gr bullets, but the jackets were too thin and the bullets were coming apart. They settled on 80gr Sierra Match King's. 1000yds is pushing it for a 5.56 either way, the rounds are damn near subsonic at 1000yds and start to tumble. If you're serious about shooting that distance, use one of the oddball calibers mentioned earlier or the trusty 7.62.

1,000 yards (as well as lesser ranges) is possible with a .223 based cartridge.
Special barrels, sights, bullets and reloads are required. Chrome lining and ACOG' s need not apply. Forgot a important part. SKILL A .22 will shoot over 1K |

I shoot this at Reade to 1000 with 75-80gr bullet wts and iron sights:
26"Krieger 1:7.7" TR It does not score as well as my 308 or 6.5-284 bolt guns but it scores very well against competitors shooting equal cartriges. Spend your money on a good pipe and accurizing the upper. Spend your time working on bullets and reloading! |

An AR service rifle can get to 1000 yards with a 1-7 barrel and 80gr Matchkings or JLK or Berger VLD bullets. The 77's or 75's can't get it done. If you want to shoot out to 600 yards you can use up to a 1-8 with the Sierra or Nosler 80's and shoot 10 ring all day. The 1000 yard shooting with the 223 is outer limits stuff because of the 20" barrel. I would recommend the M110 platform for 1000 yard shooting in service rifle configuration (M118 LR or equivalent handloads). It's approved for competition. An AR in 223 in match rifle configuration 24-26" barrel is alot easier to shoot at 1000 than the service gun(sights are superior on a match gun).

what are ya'l talking about..??? the 5.56 regular geen tip millitary LC ammo and a M16-A2 service rifle "IN MY HANDS" hits the X ring at 500 meters everytime... Oooorah!
i'm sure if this man builds a match grade rifle with a longer than 20" match barrel, using handloads taylor'd to his rifle with a good bipod and "OPTICS" i dont see any reason why he should'nt be able to get hits out to 600-800yds, we were tuaght an area sized target at 750meters with IRON A2 SIGHT'S im sure if he use's a 24" match barrel and Optics he should be able to produce hits at least 600-800yds... at least you would want to think so... now i personaly wouldn't want to be hitting out that far with a 5.56 just becuase of the other more advanced options that are available today, (6.5 sporter/grendel) just becuase i feel even though the 5.56 will get out that far i dont think the roound is an effective round that far, my personal limit for a 5.56 would have to be around the 500-600 max... and thats only if thats what i have in my hands at the timne of the opertunity... if i know im going to be shooting at a distance longer than 300-400 im not even taking out the 5.56... that would have to stay in the bag... and im pulling out the 6.5 but to each there own... i think it can be done... id op for a 24"- 26" bull barrel fluted, get everything profesionaly blueprinted, and handload some good ammo, and have at it..
