Sounds like you are on the right track. I would recommend trying more than one bullet to start out, though. Part of the fun is trying a few different bullet/sabot combos. Plus, what one rifle shoots well won't always work in another. Having a couple different bullets and sabots on hand for experimenting is always a good thing. A couple other good bullets to try are:
300 Gold Dot
250 XTP
300 XTP
Barnes Expander 250 or 300

Actually, there are a lot of good bullets out there, and we all have our favorites.
