I ran across this post and thought I'd chime in with a pic of my favorite turkey thumper. It's a SBEII with a Kicks Gobblin Thunder that I shoot 3.5" Winchester Xtended Range #6's out of.
Benelli M2 12 gauge w/IC choke
Benelli M2 20 gauge w/IC choke
Opening morning, I will be sitting in my blind with the 12 gauge, but when the weather is right and the hens are on the move, I'll be running with the 20 gauge.
Good luck everybody....it finally has come time...boom,boom,boom.
