Nitro #7's
Hevi-13 2oz #6's
Winchester Xtended Range 1.75oz #6's
So far I am liking the Hevi-13 2oz #7's as well, but I haven't tested them enough to call them a favorite of anything.
hunt12ga; Even sticking with lead I honestly have no clue why anyone would shoot #4's at turkeys. Do you have a particular reason you shoot #4's?
