When in doubt, go big. Of your choices my preference would be the Bob. I have an 84M in 308 and it is a dandy rifle and has been used up to zebra. The 7-08 would be a fine choice also.
Don't have any experience with the 260 and the my experience with the 243 was long ago and bad because of the bullets available at the time.

I am continually astounded at how quickly people make up their minds on little evidence or none at all.
