    Dear all

    Just wondered if anyone had heard of an NXS not tracking properly or had any experience of this?

    Just shooting at the weekend and I need to check my set up when I get back but I was way out on my come ups in terms of actuals vs ballistic programme.

    I am not saying it is the Nightforce (I love their scopes) but just trying to diagnose what it can be. The bummer is I will prob have to wait until the weekend due to day light hours at the moment.

    ANyway any experiences that you would like to share would be v appreciated.

    Thanks

    JB

    Did you happen to give NightForce a call and run your situation by them? They are great people to work with.

    Having said that...I did have a problem with a NightForce BR scope several years ago. Talked with the fine people at NF...they said send it in. It happened to be a problem with some bedding material for some lens. They fixed it...put a new battery in and sent it back second day air. The scope was gone for @ 4-5 days total.

    If you've ruled out all other possibilities...Give NF a call...IMHO.

    Only once, which is pretty good considering. An 8x32 NXS crapped out on me. Customer service was pretty quick. I guess when you do not have thousands of scopes breaking every day timelyness is a easy to obtain.

    I'm assuming nothing as a given:

    Was the scope fine with the same load before ?
    Are the mounts and rings ok ?
    Nothing wedged under the barrel by mistake ?
    Have you chrono'd your loads ?

    I consistantly find actual real world performance does not equal expectations garnered from 'paper'. Admittedly I use a cheap chrony and free on-line ballistics soft ware.

    The only way to ever know exactly what your rifle will shoot like, is to shoot it.

    I currently have an NXS 8-32X56 that is not tracking properly. I have contacted NF and they gave me the procedure for sending it in, I just have not done it yet. They were very professional when I talked with them on the phone.

    When I dial the scope up, say from my 100 yard zero to 20+ moa for 1000 yards, then back to 100 I end up 1/4 to 1/2 moa high. I thought I had ring slipage, either the scope in the rings or rings to the base, or even the base slipping. After using double rings and pinning the base to the reciever the problem did not go away. I eventually took an identical scope from another rifle and mounted it up and the problem went away.

    So, yes you can have a NF that does not track, but as "code4" pointed out there are many other possibilities.

    If you are simply going by what your ballistic program says your dial up "should be" I doubt very seriously it is the scope. You might check the archives, there has been a lot of discussion on this site about why ballistic programs often do not match up with the real world.

    I assume your problem is vertical?? You can test by shooting a group at 100, then dial your scope 20 or 30 moa up, then back to zero. Shoot it again and see if your shot goes into the same group. Do that several times and if you are seeing your shots start to drift high or low then you may have a problem with the scope or mounting system. If it keeps putting shots into the same group then you do not have a problem with the scope or mounting system.

    Or try a box test: One shot at each corner of a 1" block at 100 yds. With 1/4" adjustments, move reticule four clicks to each corner. Fifth shot should return to the first shot position. But your rifle must be accurate in the first place.

    Several years ago, I bought a used NF 12-42 BR model. It would not track. Called NF and told them I bought it used. The nice lady told me to send it in for inspection. About a week later, the brown truck made delivery to my front door. No charge, and NF paid the shipping. The scope works fine now, but I do not know what repair was made. Great service!!

    I suspected my NXS last week in a attempt to hit a 2inch rock at 300yrds. With 200yd zero I dialed up 2.5MOA. The wind was blowing pretty good but it was a sheltered ravine. First 2rds were off by over a 6+inches high??? 3rd drilled it.

    Mounted it in on a new base and rings took it out this morning. First round was 1.5 low at 25. Perfect. Target reset at 200. First round was 17inches low. Went up 8.5MOA. Next round was 1.75in high. Down three clicks... Next round was 2 inches low??? Next one was right next to it. Went up 1MOA and put 2 more rounds and they all clustered a nice .5 group with the previous 2rds??

    Its going back to NF Monday. Previously I have dialed this scope from 200-1000-600-1000-200 and been right back on target.

    Setup is:

    Remington 700 308 Tactical with HS stock.
    NF NXS 5.5-22x56 with mildot.

    46gr Varget, Lapua brass, CCI LR, Hornady 168Amax.

    I have a NSX 5.5x22 on my Edge. It crapped out on me this year in Wyoming during a backcountry deer hunt. I missed a nice 28 inch heavy horned muley at 951 yards.
    I had found that the scope had shifted point of impact 7 inches to the right and a inch low at 100yards!!!!
    I sent the scope back to Nightforce to have them check it out. They told me the worst scope that the had seen returned to them was only off by 1 moa at a 100 yards. They still gave it their 72 point check as they do with all returns.
    When I got the scope back I had to call them and find out what was wrong with the scope as there was no info with the scope upon its' return.
    I was told that they had found a defect in the bonding agent that is used to seal the locking ring for the objective lens. They had found a void in the agent. This would cause the point of impact shift due to the expansion and contraction that comes with the change in the temprature.
    Iwas somewhat releived to find out that it wasn't me but the scope but very disappointed that it was the scope.
    I had total confidence in this scope /gun combo. All my confidence with this scope just went down the drain. I will always have doubt in the back of my mind now.

    i just sent my nxs 8.5-32x56 npr1 for repair.
    if you hold the back objective(the one close to eyes|) - and put little pressure up down you can see the reticle shifting.
    In 2 weeks i should get it back and i will know more then. As i talked with them it is someting wrong what need to be fixed.
    I meesed one 5x5 point bull elk this season at 200yards due to this problem. I scrathed my head so hard to understend how was possible to miss, and recheking all the equipment i noticed this problem.

    The problem with this scope was not nightforce, or the scope. It was the moron behind the trigger.

    When I loosened up the turret to return it to zero a while ago. I did NOT get the detent in the groove on the inside. But instead caught the smooth round ring right above the groove. So the locking screw was on a smooth surface which was slipping when I dialed resulting in funky readings.

    Lesson learned when moving the Turret to Zero. PRESS DOWN on it and make sure its all the way down before retighting the locking screw.

    Faith in Nightforce is restored:D
