I am shooting a SBEII and am thinking of trying the Federal Heavyweight out for the heck of it. I ordered a few boxes of 3.5" #7's, does anyone here shoot this combo, and if so what choke(s) have you had luck with? Currently the only NON PORTED choke I have is a PG Tempest .670", which I am planning on patterning, but any other suggestions are welcome! Thank you!
