| So I purchased an 18 inch OBR 762 as my go to precision rifle. There are plenty of 600-1000 plus yard matches in the state of Washington, and I was wondering if using my OBR would be the way to go. Honestly, ill be doing a lot of trigger time before doing so getting familiar with the weapon and finding the right ammo for best accuracy. Once that's all said and done, I'd like to get into match shooting, but I was curious how it would stack up against those fancy bolt guns like GA Precision( guys out here run them)? Those GA rifles are shooting 3/8th MOA and better. I was also curious how usually the matches are scored if MOA really isn't really a factor. |
| trust me watch the super sniper dvd from larue you prolly got one with your AR. its a competetion in fort bening georgia and the team that took home the price did it with a OBR, 500 yard shot. its the best precision AR i think on the market. you lucky you got one. its my dream rifle i plan on getting one day. |
| Thanks. But were they running in the open or 308 or smaller class? From what I've been told in the civilian matches, you are scored by how tight the groups are I believe. I would also say that I am lucky because it wasn't through Larue, but my local Larue deodar that happened to get one in and they told me it was coming in a week. I took my saved money for my predatOBR preorder and went with this because I knew it was going to be a long wait. I still plan on getting one as long as it ships at the end of the year or later. The other thing was I wanted a versatile rifle that leaned more towards long range shooting. |

I got into ar rifles because of how they shoot. I prefer the ergonomics of a bolt action and the looks of a nice wood stock and deep blueing. I prefer function over form though and ar rifles built with quality bull barrels flat out shoot. Also the design is modular an any part can be replaced with relative ease without the need for machine tools or special skills.
The only area that an ar gives up to a bolt gun is lack of a camming action that allows neck sized only reloads and the lack (at least to my knowledge) of the ability to blueprint the action to make sure the bolt face is lined up perfectly to the chamber/barrel. |

gas guns are getting pretty good these days, and both have they pros and cons, but in terms of pure accuracy, a comparably priced bolt gun will smoke a gas gun, while there are absolutly some gas guns that have printed half MOA groups most AR's are hovering just under MOA, a Gaprecison, APA or Surgeon, will print half to less than half MOA most of the time. this is no shit accuracy, not best 3 or 4 shots out of 5 round groups throwing out a flyer. a bolt gun is going to be more consistant, i.e less flyers
the problem isnt that gas guns are in-accurate, the problem lies in having to shoot 308 ammunition loaded to mag length. where as a bolt gun can be loaded longer, and chamber for a round that shoots flattter. 6 or 6.5 creadmore, 6x47 lapua, 300WM or 300WSM, while a good shooter would not have a problem hitting a known distance target at say 800 to 1000 yards,the ballistics of the 308 are going to make hitting unknown distance targets difficult. for example if you range a 2 MOA target target at 950 yards and it turns out that the target is at 975, even if you rifle is a half MOA gun, you just missed the target, as the strike of the bullet at 975 is some 25 inches lower than it would be at 950. that same mistake made 300WM or 338LM, or better flying 6.5mm's round would only be a 12 inch difference which means you have doubled your chances to impact the target while gas guns are absolutly capable of winning compititions, the problem comes from the limitations of running mag length 308. your may find yourself competing with sombody who shoots a just flat out shoots a much better round than you, now if the compitions you are going to going to do are more oriented to rapid follow up shots and timed multpuls at moderate distances, say 500-800 yards than a gas is going to smoke a bolt gun. it really all depends on the compition is set up, long range, uknown distance, ill take a 300WM bolt gun anyday of the week multipul targets, rapid follow up, timed, give me a gas gun both are great tools to have, forcing youself to have one would be like have 1 golf club to play golf, it can be done, be why make life difficult for yourself |

The other way to look at things is just to go and shoot. You can never be totally prepared for competition unless you shoot competition.
Practise is good and all but the tempo,preasure and time constraints of a match are different than practise. Don't look at it as a match between you and the other shooters , the guy you have to beat is yourself. Get a good load and test it ( I always start with sierra bullets and the sierra manual . Its not the only way to go but I have found it as an easy way to go ). Have fun and good luck! |

accuracy is relative. you arent going to touch the accuracy of a bolt gun with your semi auto. bolt guns are capable of shooting in the 0.1 MOA range. have fun, but dont expect miracles. Not true. Unless you want to compare huge benchrest bolt guns to the OBR, which is apples and oranges. I have owned some of the best "tactical" bolt rifles available. GAP and APA, etc and I have owned OBR's. For me, and out to about 700 yards, 308 vs 308, the OBR gives up nothing. Other than being a bit rougher on brass. Not sure if you have spent much time with an OBR, but if you have not, I think it will surprise you. Ultimately, I came to the conclusion that it is just as accurate as my bolt guns. They are amazing, and to be honest, I am not sure why. Good barrels and good triggers, and assembled properly just seems an inadequate explanation, but I guess thats it. |
| What really impressed me about this rifle, was a sniper in my unit shot a 16 inch OBR with Tod Hodnett at 1600 yards. I couldn't believe it, but this was coming out of a Rangers mouth and this is what he does for a living. With that said, if you can do that consistently with a 308, I don't see why you couldn't compete in an open class. Plus I plan on Horus reticle for my optic to help me understand long range shooting a little better. |

Pretty sure the OBR will compete with a bolt gun for accuracy Nope. In field conditions sure, but not as an absolute. |
