Tip trimming for bore through irons
I swear I searched first guys! I'm reshafting a set of 2004 Callaway BB irons in graphite (they have graphite now but the ferrules are all beat up and I want to learn how to do this). I've got the Cally collared ferrules and tip plugs. I may ream the hosels .370 all the way through or I may hand taper the tips. What I've read here it seems to be 50/50 on which way to go.
What I can't find is tip trimming allowance. How much less do I trim the tips from the mfg recommended instructions (they don't give me bore-through trim specs)? I found one YT video that recommends 1/2" less than standard bore trim. What say you and thanks in advance!
