Combination gun can be useful, not really fond of the notion of rimless cartridges in it though. Much prefer to stick to rimmed rounds, for myself. How strong the FAIR O/U actions are, for higher pressure rifle cartridges like a 308/30-06 may be another question, as to loosening up down the road, which would kill resale value. Most of the rimmed cartridges run a bit lower pressure, and will still kill stuff inside 300yds quite nicely. Guess it depends on how much shooting you will do with it, whether or not you reload, and what you want to do with it, as to how long it will take to loosen up and whether or not, other cartridges are practical for you.
