I was using a Frank Cox Cocobolo yelper and a Marlin Watkins Bloodwood over Butternut box. They ate that box up. After I killed this bird and was packing up a bird pitched down flying to the woods behind me. I called that one in to about 20 yards with that box call. Both birds were very vocal when responding to the box call. Mr Watkins made it for me over the summer so it hasn't seen the Spring woods yet but it sure will this Spring.
