The Big Bertha 460 Driver is designed with a geometric shape close to the dimensional limit set by the USGA and Royal & Ancient Golf Club of St. Andrews for length and width. This enabled Callaway Golf engineers to incorporate a 460cc head design with a shallower face, flatter shape and the highest MOI ever in a Callaway Golf all-titanium head.
maniacjc - 10/10/11 I'm 50 and I pound this 320 all the time. I'm 6ft 220. Great job Calloway! Now if I could stop 3 putting 3 times a round I would get out of the mid 80's.
