"If those numbers sound the same to you then I guess "A 223 will do anything a 22-250 will do and more"."
If you are talking velocity that's one thing but killing power and flat shooting is close.

Yeah, I've hear rumours of exploding bullets in a 223 to give them more energy than they have when they move faster in the 22-250. I guess for all I know they are putting wings on them in the 223 as well to make them fly just as flat.
