If your bases and your rings are tight, then you can only have one of three problems....
1. Frustration.
2. Bad rounds (probably not this one but you never know)
3. Bad scope.
Give it one more try and make sure it wasn't frustration. Check everything before you leave the house. Make sure your bases and rings are tight and you are bore sighted good. I had a problem recently with one of my rifles and it was frustration. Good luck and let us know.
