Damn, I'm a little jealous of all these .2xx's and .3xx's. I got a beautiful rifle the other day but not one of those fancy sub .5 test targets. <a href="http://s243.photobucket.com/user/dano73327/media/Guns/IMG_2698_zps655b46f3.jpg.html" target="_blank">http://i243.photobucket.com/albums/ff29/dano73327/Guns/IMG_2698_zps655b46f3.jpg</a> View Quote My wag, operator error... Perhaps with a little batch variance in ammo? My .609 target is much like yours, 2 touching and one out. I am hoping that will make it easier to earn the extra Dillo! I can't wait for my scope to return from Burris! |

Just got my 14.5" PredatOBR 5.56 and was hoping to get a .2-.3 target after seeing these! .835
Still an amazing rifle and at least have some room for the Larue shootist contest. |

Way to let the rifles do the talking! |

That's good stuff right there, hell why stop at 1200 yards? I say those OBRs are capable of much more, 1370 is a good start..
Filmed through a spotting scope with an iPhone, you will need a computer or IPad to see the hits properly sorry ETA: I guess Carl didn't know....... |

I am witnessing the exact same groups in the last picture. Two really close together and one flier off by an inch or so. More times than not in the 2 o'clock position from the other rounds. Any ideas as to why this seems to be a common occurrence? I thought it was just me, but now that I see it happens to the shootist as well there is something else going on.

All 5 are better than my test target. Hopefully I didn't come off as complaining. I am very happy with my rifle, just curious as to the cause and if I can correct it.

Just a thought here but you might check your scope mount and scope. If this 2 in one hole and a 3rd out substantially, is repeatable, it is very likely the scope system (scope/mount). A fair test to help narrow down the issue to the optic system is 5 shot groups. This is one place where 5 shot groups can give you information that 3 shot groups are not as reliable at. (I feel 3 shot groups tell you most needed info) Scope system issues can show themselves by having 2 shots touching, then 2 or 3 shots touching, but in separate groups within the same group all fired at the same POA. It shows the scopes mount is moving under recoil or the erector system within the scope is not holding. Typically if it is the mount system it will show a propensity for vertical spread rather than horizontal. If using a QR mount make sure you cannot physically cause it to move front to back on the rail, even if you cannot move it make sure it is slid forward with the recoil lug aginst the forward rail notch before tightening. ETA: It can also mean there is no problem, see if this pattern exists with 5 shot groups, if so bet the farm it's an optic/mount issue. View Quote View All Quotes View All Quotes Quoted:

I'm running a Viper HS LR 4-16x50 in a LT-104. I torqued down the bolts to the correct spec and in the manner described in mfingar's video. The only thing I am not certain of where it was located in the rail before tightening. I'll also try for 5 shot groups as well. |

I'm good, but not good enough to spread them the same distance apart ... two of 'em are always gonna be closer. Two of 'em will be the extreme spread, then the one left gets closer to one or the other of the extreme spread holes. |

Before we get into the multiple factors that can cause the observed sub MOA flyer I'm curios if it is the first round that is separate from the other two? The first round being chambered manually and the next two being cycled into the chamber. I found I could tighten my groups by just shooting a first round flyer down range and get to work with round 2. Thoughts? |

Could be a lot of things when you are talking about a large frame AR. Could be last shot in the magaIne effect. One thing is for sure: based on what the poster is describing there appears to be a pretty predictable and consistent error. What that error is, is debatable.
Trying to draw similarities between the posters groups and the ones posted in this thread is difficult though. What you are seeing are likely the first rounds fired out of those barrels. Lots of stuff is going on in those first few shots-copper is deposited in places where none existed previously. I'm not a metallurgist but for quickly shot groups down a brand new tube those are pretty outstanding barrels. j |

Dammit I was trying to edit that and look what you did!
You know that we, as shooters, are always looking for the bad-ass one hole group. Everything else must be discussed, especially after some of your recent 5.56 targets. |

I'm not 100% certain, but I do think the flier is the first shot. I'll try the first down range just as a fouling round and see if the groups come down in size. Thanks for the thoughts on what to try.

Thanks for the thoughts on what to try. View Quote Would like to hear the result. I don't use my cold bore shot or first round off the magazine when shooting groups. Not permitted to hand load so another possibility might be factory variances in loads. I was surprised when using a chronograph at the variances of same lot factory match ammo. Generally I know right away if I threw the shot. I am speechless at the quality of groups coming from Marks new barrels. To damn happy with my OBR heavy and OBR light both 16" but will try even harder to shoot out my barrels to hopefully take advantage of the future Larue re-barrel service. |

I'm Guessing Mark told all of his shooters that they have to pay for all the Dillos that they get out shot in, in the challenge. Man those groups are getting tight.

Take your time and get them junk barrels better before doin Match Grade upgrades.
This thread does not disappoint. |
