I have a nova and use a kicks gobblin thunder choke and it produces very nice patterns. A buddy of mine uses a tight wad choke in his and he gets very nice patterns with it. My buddy and I did some testing last week using fiocca, kent, and winchester supreme shells in 3 and 3 1/2". By far hands down, the winchester sumpreme 3 1/2 #4 shot did the best. It kept the same pattern and point of aim at 20 yds to 45 yds. I hope this info helps you and good luck this spring.
