I wold use them. Can't see any reason to get a 338 mag or 340 mag and use bullet's in them I could get in a 30-06. They are gonny have a lot more velocity and if they are cup and core bullet's may have a tendicity to come apart from the velocity. Internal damage will probably be more than I'd care for. For me the worst thing might be internal damaage that could result.
