Trying to reshaft some Mack Daddy 4 wedges and the hosel depth seems a lot deeper than shaft will allow, .355 shaft. There is a ridge inside hosel, old shaft came out fine, one wedge had quite a bit of epoxy under tip others did not. Looks like you would have an insert of some kind or a lot of epoxy under tip. What am I missing?
I have seen this before and a couple of things come to mind. Callaway may just have not gotten the one shaft all the way to the bottom of the bore. Since he has more than one of these wedges I would clean out the hosel bore and then compare the bore depths to see if they are all the same. If the one that has epoxy at the bottom of the bore measures the same depth as the others the bore could be a little small at the bottom or the shaft tip of that shaft a little larger. I would first dry fit the new shafts to see if they are installing all the way to the bottom of the bore and if not I would have use a letter “T” size (.358”) to slightly open up the bottom of the bore so that the shafts would install correctly.
