I am trying an arrow build using a bunch of Carbon Express PileDriver 450 Hunters (300 spine) that I have laying around. On the Carbon Express Feradyne website, they only list one diameter measurement- and don't specify if it's ID or OD. Anyone know off the top of their head if it's ID or OD? I really don't want to call Feradyne; their customer service is suckass. In case anyone was just going to shoot me the actual specs; these shafts are older- I would say 2015? Older PileDriver shafts have slightly different specs than the brand new ones. Older ones are listed .3 grains heavier and slightly smaller diameter (whichever diameter) than brand new.
If you look at the chart on the bottom the .318" is the outer diameter and if you look down to the nock size it says .244 for inner diameter
thanks but are these are the newer ones? The GPI is a little different. Maybe the diameters are the same.
