congrats on your xbow. i would try 100-125 or 150 gr. broadheads. that crossbow shouldnt be too picky. as far as arrows go the factory arrows are good but many use black eagle excutioners as an alternative arrow.if you get a chance check this forum out. they know everything Excalibur. http://www.excaliburcrossbow.com/php...wforum.php?f=1
