go buy 20rnd boxes of as many different 556/223 ammo you can find in as many different configs and then go to the range - only way to find out. barrels are finicky for the ultimate load - may be 52grn or 69 or 77 - there is no formula for the best for your particular barrel so that is why you need to try as many as possible.

I shoot 55 gr FMJ Wolf ammo out of my 10.5" SBR with a 1/7 twist.
That is just plinking though. What are you looking for? Accuracy, home defense, critters, etc? |

I have a SBR 10.5" barrel with a 1:7 twist, what is the best grain ammo to shoot out of my barrel from maximum accuracy? If you want accuracy, you want the heaviest/longest bullet you can fit in the magazine, that will properly chamber, and handloads. 77gr SMK is a good choice and your 1:7 barrel will properly stabilize it. The Black Hills 77gr Match ammunition uses it, if you want factory. Also, a longer barrel. |

The Black Hills 77gr Match ammunition uses it, if you want factory. Also, a longer barrel. Complete BS. Just because a fast twist barrel can stabilize a heavier, longer bullet like the 77 grain MatchKing, does not mean that the heavier longer bullet will be the most accurate bullet from that barrel (out to 200 yards anyways.) Both of my Noveske N4 light barrels with 1:7" twists shoot 55 grain bullets more accurately than the 77 grain MatchKings. The same thing applies for the length of the barrel. My 24" Krieger barrel with a 1:7.7" twist barrel also shoots 55 grain bullets slightly more accurately than the 77 grain MatchKings. 
LHCSWAT08, As already posted, for accuracy, you need to try a variety of match grade bullets to find what shoots the best from your barrel and for the sake of the gods, stay away from the FMJ loads. |

thank you, this is't a match gun by anymeans, i'll post a pic when i finally get my optic in. I just have quite a few 55 grain bullets and some heavier rounds... i was considering selling whichever was "less accurate" out of a SBR and buying more of the other.

I agree with Molon. I have several 1/7 that shoot 55 grain best and some that shoot 62 grain best. I even have a 1/9 Hbar that like 75grain. You gotta try various rounds and see for yourself. In general American Eagle 62 grain FMJ shoots the best out of most of my ARs. It was cheap and plentiful a few years back and shot better than the expensive ammo from BH and Hornady! I will add that I don't have any ultra precision Ars- just service grade and one NM Hbar.

I try to buy ammo in bulk cause thats what I plan on shooting.I'm going to shoot the 62 gr green tip penetrator Lake City makes in my 1/7 twist.It's the cheapest ammo I can find that shoots really good in my gun.I can't afford the dollar a round stuff.I'll just have to be happy with groups about an inch instead of sub moa.My barrel is a Daniel Defense cold hammer forged it's supposed to shoot good.

You think it is BS because you are not shooting at ranges long enough for the massive BC advantage of heavy, boat tail bullets to matter. Give those 55gr bullets a whirl at 500 yards. Applied Ballistics For Long Range Shooting is a must read. I think you'll discover a lot of great information. |

1/7 will handle up to 90 grains, but it won't fit your mag anymore. Knock off a bit and make ....oh say an '87' grain.....

To the OP I suggest that you try as many different loads as you can to see what your gun likes. what may go good in your 1:7 might not work as well as someone else's of different make or even from a different production run. Check out the ammo section Molon has many different reviews for several types of ammo out of various twist rates/ makes of rifle. Oh, and to the newb with less than 20 post, Molon contributes alot of good info to this forum and knows what he is talking about on this type of stuff. Might want to post less and read more before you try argue with someone that holds a rep like Molons.

LHC Swat 08.. Accuracy is not the 10.5" forte so any good bullet should do fine.
Secondly if were gonna talk dick swinging Molons is gonna be much bigger than yours here. You should try being more polite. The whole cop being a dick thing gets old. |
