Great Big Bertha 23 loft progression
The 28° 7-iron is the clearest single reference point for how this set is lofted. Loft helps explain distance structure, but it does not by itself predict launch, spin or carry.
Where are the tightest and widest loft gaps?
The tightest static gap is 3° between 5-iron and 6-iron. The widest is 5° between 8-iron and 9-iron. Those are the first transitions worth checking if real carry gaps look compressed or stretched.

Great Big Bertha 23 Loft Intelligence
These derived specs show how the numbered irons are structured instead of only repeating the factory lofts.
28° loft
vs ~35° traditional 7i
3.8° average
Highly varied
Iron-only spacing: The tightest numbered-iron gap is 3° from 5i to 6i. The widest is 5° from 8i to 9i.
Progression shape: The long irons are more compressed at 3° average spacing versus 4° through the mid/short numbered irons.
Loft Consistency Score: 44.7/100. This derived score measures variation in numbered-iron loft gaps. A score of 100 means perfectly even static-loft spacing.
Spec note: Factory lofts can vary by model year, region, handedness or special configuration. Verify an exact club against Callaway documentation when a single degree matters for fitting, replacement or bending.
