What we say...
Built for distance, the Big Bertha irons are hollow and feature the first “360 face cup” Callaway has put in an iron, with a perimeter ring and variable face thickness to boost distance away from the sweetspot. Callaway has used a different heat treatment on the clubface to increase its strength, allowing them to make it even thinner. Internal “standing wave” technology carries over from their woods to position the CG low and forwards. Adjustable hybrids in the set also boast the standing wave technology as well as a speed frame face that boosts ball speeds across the clubface.

Has all the hallmarks of a super-game improver iron – plenty of offset and a thick top edge. Two white grooves on the bottom of the face make alignment easier, all contributing to an easy-to-hit look at address.
Feels jumpy off the face but there’s still a little bit of softness there, much more like a hybrid than an iron, but with more height and control.
As expected, very impressive. There’s a lot of hitting area down to the length from heel to toe and the offset may contribute to higher launch, spin and control.
Callaway has made some big distance claims but from my testing there’s plenty of substance there. The shafts are a quarter-inch longer and the lofts are strong (30° for a 7-iron) but are the same as X2 Hot and the Big Bertha certainly out-carries these. The flight is high and pretty consistent through the set without being too spinny and climbing excessively. Narrower sole widths in the short irons makes them playable for game improvers, although mid-handicappers may not like how much of the back of the long irons is visible at address. If you’re looking for more distance, these irons are for you.

It feels like a hybrid and goes a long way. A fair amount of offset and offers a strong flight with loads of forgiveness.
At address, it’s confidence inspiring by being thick and chunky. The double white score line helps alignment. It feels flush from the centre and even shots struck very low on the face flew pretty well. Boasts a hot feel overall with a high flight.
