this will be my first time out turkey hunting this season . i was wondering what would be a good combonation with what i have to hunt with. i dont really have anywhere to pattern my gun so this will be a guessing game . i have a 12 ga. bps 28" barrel with a browning xfull turkey tube. a friend told me with that tube i should go with #5 shot. any suggestions on shot size, hevi shot or lead or brand shell would be appreciated . thanks!
