Deviation from Mechanical Zero

[Slyde]

Hello all,

Is dialing 9 MOA windage after mechanically zeroing my scope excessive on an Airgun?

I’ve tried to narrow down if there’s a problem with rings or the picatinny rail by changing the rings front to back and also tried a Weaver one piece MSR mount and it always comes back to 5-9 MOA windage in order to zero.

I do not understand your question but will take a stab at it. Are you saying to centered your reticle and then had to dial in 9 moa windage to zero your scope/gun? If so, 9 moa is kind of a lot but barrels sometimes need that much. Most if not all scopes can do it, I think. If you go to the absolute limit of the scope mechanically it might affect the image you get but I would not think 9 moa would be a problem that way.

Yeah, that’s it. I mechanically centered the scope and it required 9 MOA to zero.

It just seemed like quite a bit of dialing to zero.

Thanks for the input, I appreciate it.

Burris Signature Zee rings with offset inserts can get you within a click or two of mechanical zero. I use them a lot.

Thank you Danoh. I will check them out.

9 MOA is about 3 Mil. If that's all it took to zero I wouldn't worry very much about it.

What's your zero distance? That can greatly effect adjustments.

That’s cool, I just don’t recall needing that much adjustment in the past with other guns(powder).

I’ve had pumps and springers but this is my first go at PCP airguns.

iI’m zeroing at 46 yards but didn’t think that played too much of a role. MOA is MOA , MIL is MIL. No?

Thank you

MOA is MOA and MIL is MIL, but MOA is not MIL. For example, if I was going to hold over at 50 yards, I would hold over 2.3 MOA or .7 MIL. Or I would just click 18 because I'm using a MOA scope. If I was using a MIL/MIL scope, I would click 7. So, as has been said, 9 MOA is about 3 MIL. Depending on the scope, 3 MIL is either a third of a revolution or half a revolution, which isn't very much for a windage adjustment.

Ahh, I get what you and ctshooter are getting at now.

Thanks for the help all, much appreciated.
