I had the same problem with my encore when I put a 3200 scope on. Seems they don't have as much adjustment as some scopes.

I ended up shimming the rear of the scope base with some aluminum shim stock. Or you can cut some from aluminum cans.

Some people don't like the idea of shimming but it seems to be a problem with TC. Encore, Omega barrels.

Or you can go to Burris signature rings or a scope base with built in MOA.

There were a couple posts on this subject a while back if I can find one I will bring it up.
