The Mizuno JPX-850 Forged iron is a pretty club with more distance than most other players irons. The feel is harder than expected for a Mizuno with “forged” in the name.
“I just want to say one word to you. Just one word. Boron.”
Yes, boron. That’s the big selling point behind the new Mizuno JPX-850 Forged irons. Mizuno claims that they’ve been working for 6 years to add boron to their Grain Flow Forging process, and the result is an iron that produces more distance than traditional forged irons.
The JPX-850 Forged is definitely among the better looking irons in the “forgiving players club” segment. The top line and sole are thin enough to appeal to better player, but they’re not paper thin. The offset is fairly minimal, and a rounded toe creates a classic appearance.
The cavity is a little busy, but the all-silver color scheme balances that out well.
Sound & Feel
Feel is the thing most golfers associate with Mizuno, and it’s the one area where the I was really disappointed in the JPX-850 Forged irons. The feel at impact is quite hard. For a club with “forged” in the name, I expected a much softer feel.
I was also surprised at the lack of feedback from this iron. I hit the JPX-850 Forged back to back with the JPX-850 and the amount of feedback was nearly the same. With both clubs, shots anywhere near the center feel almost identical.
Whether it’s the boron, the “Ultra CNC Milled Pocket,” or something else, the JPX-850 Forged irons are long. In fact, in our testing, they were longer than their SGI brother, the JPX-850. We found that these produced more ball speed and had lower launch and spin. All that added up to 9 more yards total (7 carry), on average.
In terms of the forgiveness, the JPX-850 Forged is average for this category. Slight mishits will still end up somewhere on the green, but you’ll be in bunkers and lakes if you wander too far from the sweet spot. Mizuno recommends these clubs for 6 to 16 handicaps, and I think that’s right on the mark. They definitely don’t stand out for forgiveness, but they’re certainly easier to hit than blades.
If you want a club that makes you look like a player, but you don’t want to give up distance iron yardages, the Mizuno JPX-850 Forged irons are for you. Though the feel is lackluster, the distances this set produces will make up for it in the eyes of some players.
