Thanks for the thoughts. Mike, sounds like I need your help. Gun is in the mail with a couple of flats of shells for testing. Send back whenever!
Actually I was trying to reproduce McKay Browns convergence test after reading about his methodology in the Dallas book. I found it most interesting that cast can alter the results of this test. I had cast added out to my 3/8ths for both guns so I was interested to see if this affected the results of the pattern. Ill try some of these other ideas next time out.
