OK. I am not sure that I did a good job of patterning. To begin with I needed more paper and much was wasted on what I call "snap firing". I also screwed around with taking some shots with 7/8 loads and others were 1 oz. I think it best that I rule out differences between loads and will do one or the other.
I may have done things wrong, but I think my choke shoots too tight for a modified.
