Well picture it this way:

5-10 Yards your trying to hit the turkey with a softball sized pattern

as opposed to

30-35 yards your trying to hit the turkey with a 30" circle of a pattern


It would be alot easier to hit it at a further distance within reason (20-35) rather than up close and personal because the pattern has time to open up.

probably cant in every situation, but why not shoot the turkey as soon as it enters comfortable gun range, instead of waiting for it to get this close. I waited for it to get closer and closer one year and blew my opportunity because after a LONG STORY i didnt even get a shot because i waited too long.
