I have a 450 Bushmaster with a Nikon 3.5 x 10. The scope was mounted and boresighted by my local gunsmith.
I finally received some ammo and went to the range to sight it in. The first 3 shots left a nice group, just not on the target (12 inches hgh and 14 inches to the right.) I tried to adjust the scope but there was not enough adjustment to correct the side to side movement. I ran the adjustment screw all the way out and back down to make sure it was properly seated but 6 inches to the right is as close as I could get it. I removed the scope checked the mount remounted it with the same results. The good news is the gun groups well. Is there something else I should check or is this just a bad scope?     Thanks

How does it group with iron sights?

See if you can borrow one of those laser boresighters and go out on a dim day with a sturdy bench and see if there is an issue with the rifle.

I have'nt tried Iron sights, how could the rifle be that far off?  I'm going to pull a scope off something else and try it this weekend if the rain holds off. I think it must be the scope. At least I hope it is.. I'll let ya know....

It sounds like it's mounted cocked or something.Good groups rules out loose mounting,and of course it could be a scope issue.Is it a new scope? Was it mounted on something else and worked good on it?Post a pic of the rig if you can....

The scope is probably the culprit, I only mentioned checking the iron sight vrs bore sight simply as a tool to verify the scope or it's mount being off. I have seen the internals fail so that no adjustment is possible and one or both of the cross hairs move fully to one side.

Here's my 450. The scope is clear and the mounts are straight and tight. I think the problem may be the Scope, it just won't adjust any more to the left. .When the rain stops here I'll try another scope and see what happens.
