Newbie Question - Scope shoots high
 

I have a crossbow that I borrowed from a friend. It's a Barnett Quad 300. Seems like a good enough crossbow, but it shoots WAY high. I've lost a bolt and target point already. I tried putting washers under the front mount, as you can see in the picture.

I have NO idea what the problem would be or what steps to take. No amount of dialing in the adjustments seems to help. I'd appreciate whatever guidance you can offer.

the picture didn't work... Try it again, you are doing the right thing by raising the front to lower your point of impact. but make sure you're doing something permanents, any thing that can move or be bumped won't hold aim. Try the pic again and we'll try to help ya out.

Check your turrent and make sure your crosshair is moving . Put the crosshair on the target and turn the adjustment knob to make sure it is moving up and down. you should be changing your poi if it is working.

First, make sure the base is positioned correctly and fastened tight. Make sure the rings are the same height and are tight as well. Don't just look at it, make sure they have at least 15-20 inch lbs of pressure. (Snugged tight, esp the base). Make sure the bolts holding the barrel of the bow to the stock are tight.
Now see if the scope TRACKS. Turn it all the way down and shoot at a bag target from not more than 10 yards. Then turn it up 10 -20 clicks and shoot again - AMING AT THE SAME SPOT as the first shot, from the same distance. Did the second shot impact higher? If not, it could be the scope's reticule is loose (broken). Just to make sure turn it up another 12 clicks and try again. Still no change? It's definitely broken.
If it did move, you could try shimming the front ring. I use pieces of aluminum can cut to the same with as the bottom of the ring, covering only that half of the ring. I would not use more than 2 layers of shims, too subject to slippage.
Assuming the scope is mounted correctly and tracks, then there may be several issues. I'd start by changing the scope AFTER making sure the bow is assembled correctly and tightened down well.
Good luck.
