I thought you are referring to optical center which is the position were the erector assembly is centered in the scope.

Hope some of these terms help with learning more about scopes :)
yep im still learning all the right terminology so i can get my questions across properly,
i was referring to the position of the erector assembly inside the scope,and making sure its dead
center before i start zeroing ,but what Deadshot
is saying is definitely something i will be trying at the range,sorry for a late reply ,work is killer at the mo.
