Any reason why you need Triple-X shafts for hunting? I would recommend using a smaller diameter shaft for hunting anyway. Those "fat" shafts are great for line cutting, but that's just excess surface area (i.e. more friction) for a hunting shaft.
Don't get me wrong, I too would prefer to use the same shafts in my 3-D shoots as when hunting (less changes to make at the end of either season), but I'm not sure those shafts are recommended for hunting.
However, if you must use those shafts, I believe this link
may be of some assistance. You would only need the glue in adapters. Also, with a 0.383" inside diameter, you may be able to use an insert for an aluminium arrow (probably 23xx to 25xx). You'll have to check to see what size fits best.
Hope this helps,
