Typically a "turkey choke" is very extended to help tighten the pattern (and lengthen the shot string) more gradually and hopefully lead to a tighter, more uniform pattern. That being said I place more value on the correct load and choke combo and for me over the years it has lead to be a Primos jellyhead with 12ga 3.5" Hevi 13 #6 with 2 1/4 oz of shot. Deadly past 60 yards.
