Yes that is the main purpose of loosen the screws, but you can get a little more adjustment too, not much but it could help in some situations.all loosening the screws does is to allow the dial to be zeroed once the scope is set.
Also it's hard to figure out what's going on some times without actually messing with it. I hope it's something minor

I think the rail on the rifle is not aligned properly, and that the problem is not with the scope at all. The obvious and easy solution is to shim the scope mount.
Mick, what would be the best way to shim the scope mount. When I got the receiver back in 06 to build my PSL kit the rail wasn't cut down for my Romanian scope to work. I ended up using a dremel tool to trim the rail down to get the scope to fit.
Use a piece of feeler gauge to shim it. Some where on the net there is a tutorial with pics, but I can't find the bloody thing.
Basically all you need to do is to place a shim under the rear of the mount where the little bolt secures it. You will need to remove or at lest slacken the brass coloured screws first.
Thanks Mick for your help .
