3" loads for IC .665 and 870 28" barrel ?

[buckeyejim]

Found a good deal on a barrel with an unfired .665 Indian Creek Diamond Strike choke. Any suggestions on what shells to try in this combo ? Was gonna buy a barrel and another Sumtoy choke to go with it but figured I would shoot this choke and see what it can do. Will be picking it up this week. Anyone tried the long beards with this choke ? I have a Sumtoy in my 20 and love it. Thanks for any opinions.

I have that same choke but I shoot 3.5 in my 870. The longbeard #5's are very tight with a very even pattern.  You will either steamroll him or miss.
