What the differences mean
At the 7-iron, the I-302 is 34° and the I-403 AD is 33°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the I-403 AD should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the I-302. Across the 10 clubs both sets share, the I-403 AD averages 1.1° stronger, with the largest gap at the SW (57° vs 55°). The pitching wedges are 46° and 45°; the stronger one leaves a 5° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the I-302 7-iron sits 0.5° flatter (61.5° vs 62°), which nudges start direction slightly right for a right-hander.
The sets are built differently: the I-302 runs 2-iron to SW (11 clubs), the I-403 AD 3-iron to SW (10 clubs).
The I-302 is a players iron and the I-403 AD a game improvement iron, so they sit 2 steps apart on the forgiveness scale. The I-403 AD is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The I-302 trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
The I-302 is listed as forged cavity back and the I-403 AD as lost wax precision cast cavity back. Forging, as in the I-302, is generally credited with a softer feel; casting, as in the I-403 AD, allows more complex cavity and weighting shapes, which is why it dominates forgiving irons. The I-403 AD adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch.
The I-403 AD came out 1 year after the I-302, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.
Which should you choose?
The I-403 AD is the stronger-lofted set — up to 2° stronger than the I-302 on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the Srixon I-302 stronger lofted than the I-403 AD?
No. The I-403 AD is the stronger-lofted set: its 7-iron is 33° against 34° for the Srixon I-302, 1° stronger and worth roughly 3 to 4 yards of extra carry.
What is the loft difference between the Srixon I-302 and I-403 AD?
At the 7-iron the difference is 1° (34° vs 33°). The largest gap on a shared club is 2° at the SW, and all 10 shared clubs differ.
Which is better for higher handicap golfers, the Srixon I-302 or the I-403 AD?
The I-403 AD. As a game improvement iron it is the more forgiving design, suited to roughly 10 to 25 handicaps. The Srixon I-302 is a players iron, better suited to roughly scratch to 10 handicaps.
