I have a set of Callaway Z22 irons in steel (project 6) shafts.

My favorites are the C8 swing weight clubs 3-6-8-9 and the rest of them are c6, what can I do to get them (meaning the C6 clubs) to C8 ?

Shorten them at the butt ?

First of all, I'm a bit confused on your first sentence. Please clarify...

  • Do you have X22 irons, or maybe X22 Tour ? (Calla made no Z22)
  • Do you have Project X 6.0 shafts? (X22 irons came with stock Uniflex shafts, while X22 Tour came with PX, or TT Dynamic Golf S300 shafts as stock. Of course, someone could have ordered X22 irons with a PX shaft upgrade)

If you want to bring swingweight C6 irons to C8, you would need to lengthen the shaft. But, you don't want to do this - it will mess up the shaft length gaps, and the resulting distance between different irons. For the X22 irons, the 3-iron has a 39" shaft, and the remaining shafts on numbered irons get 1/2" shorter as the numbers and lofts get higher.

You need to add more weight to the head area of the 4, 5, 7 and PW. ( In irons, 2 grams added to head = +1 SW). You could do this one of three ways:

  1. Remove the grip, pour about 4 grams of tungsten powder down the shaft, and stabilize it with a rammed cork... Re-grip.
  2. Remove the shaft, insert a 4-gram tip weight into the tip end of the shaft, and re-epoxy the shaft into the hosel.
  3. Put 4 grams of lead tape - or two squares of 2-gram rubberized tungsen tape - on each clubhead.

If you have a golf shop do this for you, also have them check the irons to see if they make factory specs before doing the adjustments. Make sure your set doesn't have faulty shaft-trim lengths that are messing up the swingweight.

C8 seems low for men, especially someone swinging 6.0's. I fooled around with a 43 inch C5 driver for a while and it felt like I was swinging a shaft with no head, couldn't feel it. Anyway GW's sells bottles of powder, corks and rods for next to nothing. But if I was going to mess around I would buy a cheap SW scale and make sure the SW is what you think it is. You could try lighter grips I think Winn makes some in the 28g range.

Thanks to both replies.

I have a GW swing weight scale and a 1/4" roll of lead, I kept tapping different lengths of lead roll to the hosel of the C6 4 iron and to get it to C8 it took 10 gr.

Does this sound right?

I'm assuming you have one of the basic scales which requires you to "eyeball" the weight changes, rather than getting a digital readout to the tenth of a gram.

If you used the naked eye, I would guess you would need 4 to 5 grams of weight to make the change to +2 swingweights. So, I'm a little surprised it took so much lead tape.

By the way, are you the first owner on these irons? If not, who did you buy them from?

You might want to take the irons to a clubfitter to get them checked over.

I NOW have a Ralph Maltby swing weight scale, Ed Mitchell 4 gr weights, there needle grip remover and there iron corks & epoxy and the epoxy is drying right now.

As soon as it's dry, i'll re-install the grips and see where the SW is at.

Many Thanks for your on going advice WUTiger :beer:

Ok, grips on and there real close, maybe additional 1/2 t0 1 gr would have got it dead on.

Thanks again !!

If you're within 1/2 to 1 gram, your process variance is less than 1/2 a swingweight. No one can tell the difference between say, D0 and D1, so you're in great shape.

Swing on!

    • Nah, man. People have been testing clubs like this for decades at this point. Even 35 years. @M2R, are you AskGolfNut? If you're not, you seem to have fully bought into the cult or something. So many links to so many videos… Here's an issue, too: - A drop of 0.06 is a drop with a 90 MPH 7I having a ball speed of 117 and dropping it to 111.6, which is going to be nearly 15 yards, which is far more than what a "3% distance loss" indicates (and is even more than a 4.6% distance loss). - You're okay using a percentage with small numbers and saying "they're close" and "1.3 to 1.24 is only 4.6%," but then you excuse the massive 53% difference that going from 3% to 4.6% represents. That's a hell of an error! - That guy in the Elite video is swinging his 7I at 70 MPH. C'mon. My 5' tall daughter swings hers faster than that.
    • Yea but that is sort of my quandary, I sometimes see posts where people causally say this club is more forgiving, a little more forgiving, less forgiving, ad nauseum. But what the heck are they really quantifying? The proclamation of something as fact is not authoritative, even less so as I don't know what the basis for that statement is. For my entire golfing experience, I thought of forgiveness as how much distance front to back is lost hitting the face in non-optimal locations. Anything right or left is on me and delivery issues. But I also have to clarify that my experience is only with irons, I never got to the point of having any confidence or consistency with anything longer. I feel that is rather the point, as much as possible, to quantify the losses by trying to eliminate all the variables except the one you want to investigate. Or, I feel like we agree. Compared to the variables introduced by a golfer's delivery and the variables introduced by lie conditions, the losses from missing the optimal strike location might be so small as to almost be noise over a larger area than a pea.  In which case it seems that your objection is that the 0-3% area is being depicted as too large. Which I will address below. For statements that is absurd and true 100% sweet spot is tiny for all clubs. You will need to provide some objective data to back that up and also define what true 100% sweet spot is. If you mean the area where there are 0 losses, then yes. While true, I do not feel like a not practical or useful definition for what I would like to know. For strikes on irons away from the optimal location "in measurable and quantifiable results how many yards, or feet, does that translate into?"   In my opinion it ok to be dubious but I feel like we need people attempting this sort of data driven investigation. Even if they are wrong in some things at least they are moving the discussion forward. And he has been changing the maps and the way data is interpreted along the way. So, he admits to some of the ideas he started with as being wrong. It is not like we all have not been in that situation 😄 And in any case to proceed forward I feel will require supporting or refuting data. To which as I stated above, I do not have any experience in drivers so I cannot comment on that. But I would like to comment on irons as far as these heat maps. In a video by Elite Performance Golf Studios - The TRUTH About Forgiveness! Game Improvement vs Blade vs Players Distance SLOW SWING SPEED! and going back to ~12:50 will show the reference data for the Pro 241. I can use that to check AskGolfNut's heat map for the Pro 241: a 16mm heel, 5mm low produced a loss of efficiency from 1.3 down to 1.24 or ~4.6%. Looking at AskGolfNut's heatmap it predicts a loss of 3%. Is that good or bad? I do not know but given the possible variations I am going to say it is ok. That location is very close to where the head map goes to 4%, these are very small numbers, and rounding could be playing some part. But for sure I am going to say it is not absurd. Looking at one data point is absurd, but I am not going to spend time on more because IME people who are interested will do their own research and those not interested cannot be persuaded by any amount of data. However, the overall conclusion that I got from that video was that between the three clubs there is a difference in distance forgiveness, but it is not very much. Without some robot testing or something similar the human element in the testing makes it difficult to say is it 1 yard, or 2, or 3?
