I will preface this by saying I RARELY make New Years Resolutions.
This year was different. I want to hit 1000 yard shot as my end goal, but this year, by the end of 2016 I want to consistently hit a 600 yard target. Background: 4yrs USAF 7yrs Army Contract I'm an AR guy... and all the ranges near me go out to only 100 yards. The longest shot I've taken was only 300 yards (Including time in the service). So, to begin my long range resolution I purchased a Ruger Precision in .308 with an Atlas BT46 bi-pod (I debated 6.5 but figured the .308 would be a better all around round). I'm still waiting on the glass but I budgeted for about 1k and I'd really like to get into a Night Force SHV 5-20x, unless a better option comes up. The big question though comes down to barrel break in. I've been told to shoot a round, clean it, shoot a round clean it, etc. for 10 shots, then 5 rounds clean it, rinse and repeat. The whole process could take up to about 3 hours. Is this necessary? Is this overkill and being way to cautious? I will be filling out a sniper log data book to keep track of my progress. Any other recommendations? |

necessary? absolutely not
but neither is it 'voodoo' or 'bs' or gale's conspiracy theory a few days ago, i posted a picture log on another forum that shows what happens, which you may find interesting. |

Great link, thank you for sharing.
This method will save me a ton of money in ammo. I purchased 40 rounds of decent grade range ammo just for the break in, this will easily cut my round count way down saving me roughly $50.00 For your help I'll email you some of my savings in an IOU form =) Thanks again. |

yw and good luck with your resolution!
feel free to take some pics and post them in that thread. would be very interesting to see how the ruger does |

thanks for journaling that process.
How do you like the 260AI? I love .260, have a buddy who recently started running the .260AI. I believe I know most (maybe all?) of the benefits of going AI, but needing to fireform brass seems like it would be a PITA. I think eating away at my barrel life just to get brass in shape would suck. My buddy said that he is still able to get great accuracy out of his rifle when he is fireforming (still shooting sub MOA), but it would still nag me. I also know Terry Cross used to win many PR comps running a 260AI, that says a lot if that's what he chose to shoot (that was several years ago, when .243 was the 6mm of choice), don't know if that is still accurate. Regardless, I always thought that there's got to be something to it if Terry saw fit to run it. What's your thoughts on running the AI? Do you believe the performance outweighs the barrel life? Not being facetious, truly interested in your opinion. (Maybe we should start an AI post...kind of a Q&A, not to derail this post, sorry about that) Thanks again. |

I'm looking forward to shooting LRSE in march partly because Terry and I are rooming together, so should be fun. I run his sentinel stocks on all my rifles too, and initially chose the 260AI because of his success with it. We talk about that occasionally, but he moved away from the cartridge years ago.
barrel life is about like 243, which sucks. fireforming is not a big deal. i have won a couple f-class matches while fire forming, so yeah, it's plenty accurate. past 5 years i just practice shooting positional when fire forming. One advantage of the AI is not having to trim necks. over the life of the brass, not trimming necks is a lot less work than fire forming. so net, brass prep is less PITA than something with a 20 or 30* shoulder imho. in the end, the real trade off is shooting a 140g hybrid at 3000 fps with R17 is a little better in the wind and makes impacts real easy to see, but is a little harder to catch trace, but most people went to it because of brass availability. (necking up lapua 243win brass before fireforming). my gunsmith insists if i ran the 260AI in a long action, i'd be able to seat the bullet at proper depth and get much better performance. he's usually right, but i just don't like long mags. now that GAP has 6.5 SAUM headstamped brass, I'd take a look at that too. more range, more barrel life, but uses more powder some friends are also using what used to be cheap 6.5 swede brass and improving it. they called it the 6.5 swedemoor. |

DStevenson: It would be nice if you had access to a bore scope so you could see how that factory bore and throat looks. But, could be you don't want to see it. Using a bore scope for even a day or two will give you a feel for how clean the barrel is after cleaning and what those rough spots you feel when patching are. You should definitely follow at least some kind of break in. It cant hurt and might pay off. Just use good equipment/guides and protect the crown when cleaning, don't pull any brushes back in the barrel IMO. Only push them breech to muzzle. I think you will be surprised how well you will do out to 600 if you have a decent shooting rifle. The difference in 600 and 1,000 is more challenging than it seems on paper with most factory 308s. I have had (past tense) some 308s that wouldn't hit steel at 1,000 reliably at all mush less make a group, but at 600 were acceptable. taliv: I see you are in TN. Are you in West TN? I went to KM Precision Shooting in Finger over Christmas break and had a great time shooting there. It was a little cool, but a fun range. Those steels out to 1,200 are a lot of fun. Lots of positional shooting, but I was having too much fun at one position and never moved. |

no, I'm east of Nashville. The PMG, PTS, and now Crucible matches are held a few miles from my house. We shoot out to 1100. I haven't seen shannon's range yet, but I used to go down to CORE when it was K&M in florida a lot. I'll be down there for the AI and MPA PRS matches this year.

Wow, those are some low spreads. The chrono probably isn't even accurate enough to measure that small of deviation! You might be shooting near 0 ES. That's not just a clean barrel, but good loading, chamber, throat, everything.
What kind of best group precision did you get shooting those groups? Also to the OP, add a magnetospeed chrono to the list of stuff you need. At only $179, its almost a must have. |

I talked to magnetospeed at length a couple years ago about this. It will resolve to well under 1 fps. I think litz also did some testing on this.
First and last group were quite small. For some reason rifle really doesn't like anything in the 36.5-37.0g range and groups open up to about 7/8" or so |

I've been considering picking one of them up because I don't want to spend $300 on a chrono, but at the same time my cheap chrono only works in the right light conditions so it's really pissing me off. Am I correct that the "sporter" version operates just the same and as good it just has a cheaper display unit that may be a little more of a pain to navigate the menu? I really only use it to check velocity as I'm also checking where I find pressure to see if my velocity is in a range typical of the combination I'm using so I know if anything weird is going on. Then use it again after I develop a load to get a baseline and make sure my ES is good. |

Electronics wise, I believe it is the same as the more expensive version. |

ETA lots of good information from these guys. |

Ok, seriously, I was just interested to know. I was being nosey. lol I didn't mean to question or offend by any means. That part in red, absolutely not. I may have been to some schools, but that doesn't mean I'm better or worse than anyone. There are plenty of guys here that shoot long range that I could learn plenty from and that includes you. I believe that no matter who you're with, there is something that can be learned from another person. If you get to the point where you think you can't learn something from someone, you need to take a step back and think long and hard about yourself. I have that same attitude in aviation as well. |

Looks like a great range! After 700 1,000 will be relatively easy. I went from 600 - 1,000 and was surprised how easy it was. (Unless the wind was blowing)

I am ... because 700 pretty very smoothly, borderline easy (granted under perfect conditions) my next goal is 1000 yards.
I really don't expect my next trip at that range to go as well but if I can squeeze it in before the end of the year; all the better. Just need to load up some more rounds and re-zero my rifle after making a change to my scope mount. |
