What the differences mean
At the 7-iron, the CB-57 is 34° and the CB-301 is 32°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the CB-301 should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the CB-57. Across the 7 clubs both sets share, the CB-301 averages 2.1° stronger, with the largest gap at the PW (47° vs 44°). The pitching wedges are 47° and 44°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the CB-57 7-iron sits 1.5° flatter (61° vs 62.5°), which nudges start direction slightly right for a right-hander.
The sets are built differently: the CB-57 runs 3-iron to PW (8 clubs), the CB-301 4-iron to GW (8 clubs).
The CB-57 is a players iron and the CB-301 a players distance iron, so they sit one step apart on the forgiveness scale. The CB-301 is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 5 to 15 handicaps who want extra distance from a compact head. The CB-57 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 CB-57 is listed as forged cavity back with progressive weight bar 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.
There are 5 years between these sets (2014 and 2019), more than one design generation. Over that time irons moved toward stronger lofts, thinner and faster faces, hollow and multi-material heads and wider use of tungsten, so the newer set is not simply a better version of the older one: it may launch and spin quite differently. Here the 7-iron loft moved from 34° to 32°.
Which should you choose?
The CB-301 is the stronger-lofted set — up to 3° stronger than the CB-57 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 Miura CB-57 stronger lofted than the CB-301?
No. The CB-301 is the stronger-lofted set: its 7-iron is 32° against 34° for the Miura CB-57, 2° stronger and worth roughly 6 to 8 yards of extra carry.
What is the loft difference between the Miura CB-57 and CB-301?
At the 7-iron the difference is 2° (34° vs 32°). The largest gap on a shared club is 3° at the PW, and all 7 shared clubs differ.
Which is better for higher handicap golfers, the Miura CB-57 or the CB-301?
The CB-301. As a players distance iron it is the more forgiving design, suited to roughly 5 to 15 handicaps who want extra distance from a compact head. The Miura CB-57 is a players iron, better suited to roughly scratch to 10 handicaps.
