I have both 223 and 308 in rem 700p. I really like them both. For "my" purposes the 223 does what the 308 can do out to 500m if the wind is playing fair. With that said i plan on re-barreling my 308 to a 260 some day to give me a bit more range. My 308 load (178Amax) loses a lot of accuracy beyond 700m; but being fair is is on the cool side. My 223 shoots 69smk very well, but they still aren't cheap bullets to buy. Lately i have tried running bulk 55gr fmjs, and have been pleasantly surprised by the performance out to 500m and it makes for pretty inexpensive fun which is my intended use for the 223.
So my recommendations, if this is a serious, long range precision rig, look at the 6.5/260 cartridges. Reloading helps. If your just looking for getting into long range while trying to keep the cost down go with 223.
