I had a problem with a Grulla this year that shot 6" low @ 16 yards. I sent it back to Merkel and they contacted Grulla who then said that it was within Tolerances. Danny at Merekel agreed with me that this was crap and replaced it for me. But I think it goes to show that eventhough a 4" spread is what a tolerance should be some mfg take a more liberal stance.
P.S. I was talking to the FAMARS representative about why they would use mono-bloc construction on their fine guns and he said that barrel regulation is more difficult with chopper lump construction than with mono-bloc construction. I know this might not set well with the tradtional crowd on this board and I believe that your Rizzini is a Mono-bloc as well, But I think it is insightful.
