Thread: Pulsar N750 owners

    Pulsar N750 owners

    Guy's,

    For those of you that own one. How do you find the accuracy and more so the repeatability (i.e) does it ever loose zero on you ??. I have one here and when zeroed it shoots as good a groups as my zeiss but getting it to hold zero longer than 12 hours isn't happening. Thats twice now ive zeroed it and twice ive gone out at night only to miss rabbits. When i re-checked the zero it was up to 4-8 inches off !!

    Hello, which mount are you using, and which calibre rifle.

    The device should hold zero perfectly, and this is never usually an issue.

    Accuracy wise when zeroed I have never had an issue with the device loosing zero. Have you checked the X and Y co-ordinates are the same numerically, and its not simply creep on the mounts, or incorrect fitting?

    Are you using a lens conversion on the device?

    If you bought it from Scott Country, please feel free to give me a call on 01556 50 3587 and I will be more than pleased to assist you as it sounds like either a mounting issue, or if you are using the one shot zero function you are not confirming your adjustment properly.

    Best Regards

    Paul

    I have an N750 and the only zero problems I have had all relate to the use of an after-market doubler, the scope itself holds zero perfectly.

    I would check that the allen screws that hold the ally mount on the plastic scope body are tight, they should be put in with thread lock as they are prone to working loose and that the mount/ whatever rail system you are using is also tight.

    If all the above checks out and you are certain the rifle is also good then I would take it back, I have heard of a several N550's going back with zero problems so it wouldn't surprise me

    Paul,
    Thanks for the speedy reply. I am off out now again to try and re-zero it. I will give it a good checking over first though.The set up i have is a remmy 700 22.250, an absolute tack driver that shoots well under 1/2" groups. The rail i have on is a third eye picatinni and the pulsar directly onto that. There is a Dr Bob doubler on the end with a Sony lens fitted. The rifle is still shooting under 1/2" groups with the Pulsar but when i put it away and then go out lamping it seems to have moved. When i zero it i dont use the one shot option, ive just used the conventional option.

    I must say that the scope was bought private so not from Scott country. I will go and try what you mention and report back.

    Thanks again for the reply

    Thanks Anthony, I will try removing the Dr Bob if all else fails to work and see if that improves things.

    As I suspected, hence my question regarding a lens conversion, which is more than always the cause for a zeroing issue.

    When you pack the rifle away in gun bag, case etc, i bet the lens is moving ever so slightly and causing refraction of the internal lens onto the Digisight lens, in turn shifting your zero point.

    The comment "There is a Dr Bob doubler on the end with a Sony lens fitted." is 99.9% going to be the issue.

    Do you have a 3 or 4 stud adaptor, you will need a 4 stud adaptor for a centrefire rifle, and even then they are rated to .243 so should be fine on the .22-250 but the 3 stud is purely for rimfire use.

    I bet my chocolate Santa on my desk that it will be fine without it......

    Paul,
    Yeah it is the 4 stud adapter that's on it and like you say the 22.250 so should be good. i will try removing it and see what happens. Will be a bit gutted though if this is the problem as with the lens on it improves clarity by 100%.

    I have read of problems with even the 4 stud adaptors moving under recoil so I just wouldn't trust it to stay 100% secure, the slightest knock will affect your zero.

    I have glued my adaptor in place using epoxy resin, others have used a decent silicon, I have had no more problems with mine on my 22-250 since doing this but it still pays to treat the scope with kid gloves.

    I cannot condone "gluing" in your adaptor, as this could cause issues with warranty should you damage the weapon site.

    Fitted properly, and ive fitted loads, the 4 stud adaptor wont budge unless you are shooting more than 70grain rounds as a rule.
