I've never seen the logic of duplex shot loads. If you are taking head and neck shots, only, and #6 will kill them at your maximum range, why lose the advantage of a higher pellet count? Most of my turkeys were shot at 25 yards, or less, but I've killed several in the 35-40 yard range, all with #6. I do keep the velocity up.
I shoot 1 3/8 oz of shot for turkey, which is 309 pellets of #6 but only 185 of #4.
