The .257 Roberts AI is a neat round. I don’t have one myself but I’ve always been a fan of those Ackley cartridges, they give you a nice performance without going overboard. A friend of mine uses one for deer hunting and can’t stop raving about it. He says it shoots flat and is gentle on the shoulder plus those lighter bullets really zip. If you’re already reloading, forming brass is pretty easy which is great since factory ammo is pretty scarce nowadays.
