DNT TNC225R troubles

[Rcm]

Have a DNT TNC225R and trying to set it up on a Brocock Atomic XR.177 and can't get it to zero. Followed how to freeze Fram first shot . then Move my cross hairs down to where the shot went. I have maxed out the Y setting to the max neg possible and still can't zero . I am using the 0moa mount . Question, Do I need to get the a 20 Mao mount?

Thank you.

I have the same scope mounted on a vulcan 3hp .30 ..vulcan has 20 moa built into rail. For fun was going to put on my avenger .25 and had the same issue you are having you need the 20 moa rail

Many Airguns have O-MOA rails as you may or may not know and with the height of the scope over bore it basically blows your elevation available in your scope away. It’s definitely a flaw in the design of some Airguns. I have seen some airguns where scopes are almost 3 plus inches above bore. Example Western Sidewinder Airguns. Without tons of MOA in your rings your scope elevation is toast.
