Both rifles are 556 NATO
First has a 14.5" barrel (with 1.5" muzzle break for legality.) Second has a 16" heavy, fluted barrel. What MOA can I expect from both @ 100yd & 400yd, with match ammo? |

Smart alec answer...
How well can you shoot? Real answer: http://www.ar15.com/content/page.html?id=237 ARF user Molon has done TONS of accuracy testing. Take a look through here to see everything you could possibly want to know. |

Nice thread. I see he's averaging about 1" with 16" barrels.
Those noveski barrels are threaded, though. I want a 16", as accurate, without threads / muzzle break. Do you have any suggestions? Quoted:

16" Douglas SS Hbar/1-8 from Frank White at Compass Lake. Free Floated Barrel...RRA/Holliger Tuned 2 stage trigger, J-P Adjustable Gas Block, Harris BiPod. 
1 MOA or better with my handloads. Usually sub-moa at 100 yards. The key is ammo/hand-tuned loads and how you handle recoil on a shorty. |

Too vague; are you talking with optics, or iron sights? Are you talking benchrest, or standing, or prone on the floor? For standing, with standard iron sights, you will get 2-5 MOA. With optics, you can get between 1-3 MOA standing. With good peep sights, it can be cut down to 1-2 MOA if you practice a lot. On the bench, or prone on the ground with a rest, you should see 1-3 MOA with iron, and .75-2 with optics. There are a lot of little things that affect your shooting, so it's only an estimate. But be certain that if you walk up to a range and pull off 2MOA standing with iron sights on a busy day???? The shooters are gonna notice!

If your gun shoots 1 MOA at 100, I would not expect it to maintain 1 MOA out to 400. As the range increases, minor imperfections in stabilization, variances in muzzle velocity, non-concentric bullets etc... cause more and more inherent inaccuracy. That said, the OP's question is too vague. So many variables. I'd guess somewhere between 1 and 2 MOA at 100, 1.5-4 MOA at 400. |
