Need help with zeroing a scope on the Orion

[Karanchuhg]

Hi - I bought a fx 3 12x44 scope today and was trying to zero it at 10 yards, however ran out of elevation and I am still about 2 inches below the bullseye. I am using a hawke single piece mount on the Orion

Any help is appreciated

Is there a way that you can put a shim under the rear of the mount? Or reverse the mount and see if that makes a difference?

Hi Karanchuhg,

> I have fixed a 2-7 x 32 Centerpoint Scope on to my Orion using a UTG Single Piece mount & have not faced any problem zeroing it at 15mtrs.
> In your case the problem could be:
1. Probably your scope needs "Shimming" (Shims should not be more than 1mm thick - Best is to use 35mm photo film)
2. There could be a Barrel Droop in your Orion - Have it checked.
> As IFGian 'Tworivers' has suggested 'Try reversing the mount'.
> You may PM IFGian Pratik Mahale - He had the same problem & has sorted it out.
Good Luck

Thanks - I don't think it's a case of barrel droop, since it accurate with open sights. I shimmed the rear and seems to have resolved the issue, however it's still at about more than 3/4 of elevation.

I will try adjustable mounts that correct this issue. Do you think it could be cause I am trying to zero at 10 meters?

Hi Karan,
> Good there's no Barrel Droop
> Glad to note that Shimming has helped to an extent.
> Adjustable mounts may help.
> BTW at what magnification are you trying to zero your scope @ 10 mtrs? I understand that you have a Variable Scope. Try zeroing at 4X magnification and use a bench rest to do it.
> You can also see the video by Archer Airguns (archerairguns.com) on how to zero a scope - it may help.
> Hope you are using 14gr pellets while zeroing your scope.
Good Luck

I zeroed at 3x magnification using a rest.

Yes, very nice video, helped a lot!
I am using gsmith wadcutter pellets, the box doesn't say how many gr it is

[Karanchuhg]

Another question, how does magnification matter? The cross hair intersection doesn't change with magnification only the other 4 aiming points, but for zeroing we use the cross hair intersection, don't we?

friend fx 3 12x44 will not zero at 10yrds my guess; you should try at 30 yrds.
