Definitely shoot the broadheads before going out. Just becuase your target tips are shooting good doesn't mean your broadheads will. If anything, your bow will have to have some fine tuning done when shooting the broadheads. You can get a target at wal-mart that allows you to shoot target tips at one side and broadheads at the other side for around $20 or so. Definitely check the broadheads before shooting at a live animal...it's the ethical thing to do.
