Shotgun range = bow range?
Not hardly (In my case).

I'm solid with a bow (most times) to about 20 yds. I know guys who'll take shots 3x that long at a turkey in the right circumstances (shotgun).
"If" I chose to hunt turkeys with a shotgun.....I'd have tagged out in the first week of the '07 season. That is simply the truth.
Inside 20yds....While I still like my odds better with the shotgun.....I tend to agree with Rob.
