The Steelhead XR irons replace the XR16 irons and resemble the old X-14 irons. That however is where the similarities end. The X-Series irons have gone through multiple technology changes in the past 5 years but retain their iconic shape fi rst seen with the X-12 model. With the Steelhead XR, there’s an evolution of the 360 Face Cup which is now stretched further around the sole and the crown than ever before. This allows the face to fl ex and in turn produces amazing ball speeds across the entire face. To save weight where it’s not needed, Callaway have used a Hollow Bore-Thru hosel which allows them to move the weight improving both launch and forgiveness. A progressive CG location means that every iron is individually fi ne-tuned for optimal launch. This makes it really easy to launch the longer irons and provides consistent piercing ball fl ight on the shorter clubs. To make this possible, they infused steel into their polyurethane layer. While the polyurethane normally provides only a softer more pleasing feel at impact, the steel infused version allows them to further tinker with CG locations for optimal launch and stability. Our testing resulted in unheard-of distance gains. The Steelhead XR iron is one of the longest we have ever seen and despite the outrageous distance, the accuracy and forgiveness was second to none. We put the distance gains down to the Face Cup and of course the stronger lofts (5 degrees) in the #6 iron. The fl ight height was staggering thanks to the steel infused polyurethane layer and progressive CG. These are best suited to mid-to-high handicaps looking for distance and forgiveness from a clean compact head.
Next generation 360 degree face technology in the Callaway Steelhead XR Graphite Irons increases ball speeds more efficiently on both center and off-center hits. Steel-infused urethane bar behind the face improves feel and lowers the center-of-gravity for higher launch. The Hollow Bore-Thru hosel saves weight and repositions weight for more forgiveness. Progressive center-of-gravity throughout the irons improves launch and distance in the long irons and control and playability in the short irons.
