Ok so I know it might be a little weak to start a thread with a question about a pellet gun not sighting in within the same category as threads about .375s and .416s but what the heck. I recently bought a Gamo pellet gun out of cabelas for squirres and what not. Anyways went to sight it in and it was WAY low. So low in fact that with the scope maxed out on the upward dial it is still about 5" low at 25 yards. Is there someway to possibly shim the scope in the front or some other way to get this setup to work. Any ideas would be much appreciated.
