The bolts for my Excaliber do not have nocks. Its just an insert that is threaded with a 10-32 thread.
My buddy has a Barnette and it has shallow nocks, not the deep ones that clip on the string like a vertical bow, but just a shallow depression.
I've never used a luminox but with the xbow I'm thinking it might be wasted money. With the speed one can get from them, complete pass thru's are the norm, and you'd be looking at a red dot on the ground while the deer ran off.
For the life of me I don't understand how these TV hunters shoot a deer with a bow, and half of the shaft with the luminox hasn't penetrated the entry side of the deer??? My first bow kill was with a 45lb bow and it got full penetration through the deer.
As far as a target to shoot. Mine is 350fps, and I refuse to pay $130 for a block target at BP.
I bought the $40 yellowjacket from wallyworld. It stops the bolt, but most of the time it buries the fletchings in the block.
Now, the threaded insert that Excaliber comes into play. I built a T handle, and welded a 10-32 bolt to it.
Now I can screw it into the insert and pull the bolt from the target with no damage to the fletchings.
