My view is a little different. My .257 is on an Arisaka Type 38 action, and my favorite loads are too long to fit in my Remington 722's magazine. My view is that the 722 is ideal for a .250 Savage (or .22/250), but just a little short for the .257 Roberts, at least the way I like to load it. I suspect Remington would have sold more rifles had they chambered the .257 Roberts in their 721 instead.
I guess it depends on what bullets you want to load in your .257 AI, and how far out you want to load them. OAL should be the same for either case with similar bullets loaded the same distance from the lands. If you're happy with your .257 Roberts loads, you should be with the AI version also -- but I wouldn't be.
