Pics in pattern section but a good combo at 30 yards. Browning Belgium A5 12 gauge with 29.5in full choke barrel. 28yards and 57 degrees. 187 in the 10 with Rooster XR 2.75in #6's.
I don't have the tool to check mine with. All I can give you is 29.5 inch and full choke. Hope they do good for you!
I bought a box of Fed. Mag shok, 2.75 #5's that I'll give a whirl in my Rem 11, and my Savage 720. I also see that they make them in #7's too, may have to try them next! I'm wanting to send the savage barrel to Sumtoy, and have it threaded for Tru chokes, and then have him make me a .670, that should be bad medicine for turkey heads! I've never patterned it but the Rem 11 shoots the express #4's very well!
