What the differences mean
At the 7-iron, the MX-23 is 33° and the MX-300 is 33°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 8 clubs both sets share, the differences roughly cancel out, with the largest gap at the PW (46° vs 45°). 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.
The sets are built differently: the MX-23 runs 3-iron to PW (8 clubs), the MX-300 3-iron to GW (9 clubs).
The MX-23 is a game improvement iron and the MX-300 a players iron, so they sit 2 steps apart on the forgiveness scale. The MX-23 is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The MX-300 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 MX-23 is listed as investment cast with a cut muscle cavity and the MX-300 as Grain Flow Forged with an undercut cavity. Forging, as in the MX-300, is generally credited with a softer feel; casting, as in the MX-23, allows more complex cavity and weighting shapes, which is why it dominates forgiving irons. The MX-23's muscle-back shape keeps mass directly behind the strike for feedback and control, where a cavity spreads it to the perimeter for forgiveness.
There are 4 years between these sets (2006 and 2010), 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.
Which should you choose?
The MX-300 is the stronger-lofted set — up to 1° stronger than the MX-23 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 Mizuno MX-23 stronger lofted than the MX-300?

What is the loft difference between the Mizuno MX-23 and MX-300?
At the 7-iron the difference is 0° (33° vs 33°). The largest gap on a shared club is 1° at the PW, and 1 of the 8 shared clubs differ.
Which is better for higher handicap golfers, the Mizuno MX-23 or the MX-300?
The Mizuno MX-23. As a game improvement iron it is the more forgiving design, suited to roughly 10 to 25 handicaps. The MX-300 is a players iron, better suited to roughly scratch to 10 handicaps.
Do the Mizuno MX-23 and MX-300 have the same lie and length?
At the 7-iron, yes: both are 61.5° lie and 36.75 inches long.
