just shot these patterns out of my nef 10ga with a jellyhead 690 choke and winchester 3.5", 2.25oz, 5's and 6's
the 6's shot 152 in the 10" at 40yds
the 5's shot 154 in the 10" at 40yds
i was very very happy with the results, i have never been able to get lead to pattern over 90 for me before with any gun, but the big ole 10 put up 150's for me
6's

Good patterns! I like the 6's better as it's more even.
Have you tried the Win HV 3.5-2oz-5's?
Either or, its crazy that you have higher #'s with the bigger shot size though!
some good looking patterns
