Mike --

I found the first of your web references (in your latest posting) very helpful, indeed. Very educational.

I would like to thank you for this effort. Your first web reference sheds some considerable light on this thread and the B. Rizzini, point of impact, patterning problem -- since the required convergence of the barrel/choke axes - in the gun in question - appears to be absent.

Thanks very much for your help in this matter. Appreciated.

Best Regards,

Don
