I know, it had to happen sometime. I bought some nice new carbon arrows from wally-world and they are not the same weight as the arrows I bought from the gun shop. Be it lighter or heavier they are 6" higher at 20 yards and more at 35. I have a indoor range at my buddies work when they are closed, it is all setup for 35 yard shots and I cocked and loaded a new arrow and pulled the trigger. Less than a second after that I spent $15 dollars to hear the worst sound ever as the arrow mashed into to a brick wall. The arrow stuck in about 2" which was cool and I would have got a picture but did not have anything to take one. So are the arrows crap or just lighter than the one that excalibor sell with the crossbow? Will using the speed settings on the scope help? I re-zeroed my scope for the new arrows (14 CLICKS DOWN), and tried to turn down the speed setting on the scope but the excalibor arrow still hit 6" low. You guys know everthing so any help will rock!!
