I am usually very straight with my irons, rarely slicing and usually shaping a slight draw; however scores remain high because of distance inconsistencies between the range and the course.

Example: I chart each club during practice sessions at the range and average out my swings to achieve an expected distance. Without fail the distances never match what I shoot on the course. A no brainer 165 yard 7 iron on the range, fly the green and ends up OB at about 185+.

Club down? Tried that. The 8 iron flys the green and into a bunker at 175. Club down again? Tried that. The 9 ends up well short at 150. Each of the swings ends up well balanced and clean.

Ideas? Why the difference?
