The Apex Ai300 is the only iron in the Apex line to have a forged cavity back construction, designed for high ball speeds and consistency across the face.
The Ai300 is the most forgiving model in Callaway’s 2024 Apex line. Compared to the Ai200, it has a larger profile and a cavity-back design instead of a hollow body. It’s designed to deliver the speed, forgiveness and consistency of a game-improvement iron with a tour-caliber feel.

Ai 300 Features
The Apex Ai300 is the only iron in the Apex line to have a forged cavity back construction, designed for high ball speeds and consistency across the face.

Ai Smart Face
Like the Apex Ai200, the Apex Ai300 irons feature Ai Smart Face technology.
This face was developed using artificial intelligence and uses data (swing speed, face orientation, club delivery) from real golfers. It’s designed to maximize ball speeds across the face, tighten dispersions, and produce more consistent spin.

455 Face Cup
The Ai300’s forged 455 Face Cup is found through the entire set.
Made of a high-strength stainless steel, it contributes to high ball speeds and power across the face and creates a tour-caliber feel and sound.

MIM Back Weight
A metal-injection molded (MIM) back weight allows club fitters to find a swing weight that works best for you. It also allows for consistent visuals when building a mixed set with Callaway’s other Apex 24 models.

The Apex Ai300 irons also benefit from a Dynamic Sole for easier and more consistent turf interaction, and urethane microspheres which help produce a quieter impact sound.
