Hi all, can you use any 500mm arrow with the nock removed on the Crown arrow barrel, I asked an archery store here and they seemed to think the FX arrows may be a larger size than normal?
You have to use crossbow bolts they are larger diameter
If someone would measure the OD of the barrel then this would be the standard and "fit" would be found by measuring the ID of the arrows or bolts.
It would be interesting to see if longer heavier arrows or shorter light bolts gave better game killing performance (velocity/momentum/penetration).
