My bow is set at 60... It can be set up to 70 but you really don't need it.... I play college baseball and can hold my own in the weight room but you do not have to show off to kill a deer... it is pointless... I shot my 220 pound buck this year at 30 yards and my bow that is set at 60 was putting enough balls behind my arrow for it to go straight through the deer. I would say that you would not want to go under 50 but anything over 50 is plenty to fill the freezer.
