Take it easy fellas...either offer advice to the OP or move on.
So bought my crossbow and took it out to a 3D range over the weekend. Started it out at 10 yards. First bolt shoots way up in the air, probably about 2 feet above the target and lands on the wall, even though i had a shot shot through my scope. Second one goes into the target, and the third one is about 6 inches above target and also travels to the wall. It's my first time using any kind of bow. Would these very high shots just be a case of me not making sure the bolt was straight enough on the rail and locked in all the way? I did take about 10 more shots and they all hit the target. Some of those were from 20 yards away but those first couple of out of control shots really scared me. I'm taking it hunting soon and do not want a wild shot to happen again. Any advice would be great.
Jhog, definitly something wrong with your crossbow. I am not familiar enough with crossbows to tell you how to correct the problem.
I would take it into an actual bow shop and have them look at it. Also, see if they will give you a tutorial on how to use it and on how to address certain issues that might come up while in the field.
Practice, practice, practice. Know your limits and don't stretch beyond them. Pick a spot, aim small miss small. Shot placement with any archery equipment is critical.
Good luck on your hunt and get to a shop as soon as possible to see if they can correct your issue
