Every shotgun is a law onto itself. It's virtually impossible to predict with any degree of certainty that a particular load or brand of load will pattern best in your gun with your choke. You'll need to try different combinations for yourself. For instance, my gun will pattern #4's pretty much the same as #6's, but I can't find any #5 loads that will pattern consistently at all. I also learned my gun definitely patterns better with a clean barrel. So, at the range, I swab out my barrel between shots to make sure I'm comparing apples to apples. There is no shortcut to doing the homework.
