Hevi-13 through factory chokes in Benelli Nova 20ga. Compact?

[The Baron]

I bought a Hevi-13 20 ga. turkey choke that was marked Beretta/Benelli, but it doesn't fit in our Benelli Nova Compact or a buddy's M2.      I wish these companies would stop changing choke styles all the time (standardized threads for all gun manufacturers would be nice!). 

I've got a supply Hevi-Shot Magnum Blend 20ga. in 3" with 5,6,7 shot.   What can I expect from the factory Benelli chokes?  I'm not looking to stretch the range, just a nice solid/even pattern at 25-30 would be plenty for my needs.
