trajectory ballistic calculator ?

[Alantoo]

Scope height above the bore makes very little difference in trajectory in relation to the sights. You can verify it by comparing the same load with iron sights and 56mm Hubbel scopes. Scope height does make a difference in fitting one's face to the stock and eye alignment. Lower is not always better.

Understood...the difference in drop between our posted results was only 26"@ 1.5" or 24.6" @1.9" by the time it got to 400yds.

I was just curious whether it was possible to get a scope the size the OP specified that close to the bore.
