What the differences mean
At the 7-iron, the IC-601 is 31° and the CB-301 is 32°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the IC-601 should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the CB-301. Across the 8 clubs both sets share, the differences roughly cancel out, with the largest gap at the GW (50° vs 48°). The pitching wedges are 45° and 44°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the IC-601 7-iron sits 1° flatter (61.5° vs 62.5°), which nudges start direction slightly right for a right-hander.
The IC-601 is a game improvement iron and the CB-301 a players distance iron, so they sit one step apart on the forgiveness scale. The IC-601 is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The CB-301 trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly 5 to 15 handicaps who want extra distance from a compact head.
The IC-601 is listed as inner cavity design with back weight screw and the CB-301 as forged cavity back with variable sole and cavity thickness. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The CB-301 came out 2 years after the IC-601, 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?
Loft differences between the IC-601 and CB-301 run in both directions rather than shifting the whole set one way, so the choice comes down to shaping, feel and gapping at the ends of the set rather than outright distance.

Frequently asked questions
Is the Miura IC-601 stronger lofted than the CB-301?
Yes. The Miura IC-601 7-iron is 31° against 32° for the CB-301, 1° stronger, which is worth roughly 3 to 4 yards of extra carry with the same swing.
What is the loft difference between the Miura IC-601 and CB-301?
At the 7-iron the difference is 1° (31° vs 32°). The largest gap on a shared club is 2° at the GW, and 4 of the 8 shared clubs differ.
Which is better for higher handicap golfers, the Miura IC-601 or the CB-301?
The Miura IC-601. As a game improvement iron it is the more forgiving design, suited to roughly 10 to 25 handicaps. The CB-301 is a players distance iron, better suited to roughly 5 to 15 handicaps who want extra distance from a compact head.
Do the Miura IC-601 and CB-301 have the same lie and length?
Not exactly. At the 7-iron the Miura IC-601 is 61.5° lie and 37 inches, the CB-301 62.5° and 37 inches. Both can be bent or built to your own fit.
