Re: Scope mounting
presuming your rifle's receiver has scope base mounting holes that are properly aligned, then you should have little trouble mounting a scope to properly align with the bore.
Many shooters prefer the Kelbly/Stolle dovetail, Weaver, and Picatinny types of bases, as they don't require any twisting or turning of the rings like the Redfield type bases.
Another thing to try might be to mount your base and rings, and then put a long straight piece of PVC pipe or wooden dowel in your rings and see how closely it follows the barrel.
Lastly, don't think you need to have the scope perfectly aligned, so that you won't have to make a single windage adjustment. That's just not practical, and scopes have windage adjustments for a reason. You'll want your scope pretty well centered of course, but don't go crazy with this stuff.
