I have no idea how much my arrows weigh. Guy at the shop where I bought the bow said they were close to the minimum for 73# pull on this bow (X Force). I shoot the Pro Series 200X Weave Radials. They are 27" long with 2" blazer veins and a 90 gr tip. Any guesses on this?? 325 gr 400 gr??? Help me figure this out, I have no way of weighing them!!
