I have an AI. I've only shot the 215 SGKs from the bench. (Although I carried them on an unsuccessful elk hunt.) They shoot like a house a'fire over Re-15. The "too hard" info is news to me. I believe it, but I don't think it'd discourage me from carrying them again on a hunt.
That said, I have recently been getting the rifle ready for a high country muley hunt. Bucks are hard to come by, but, if you see one, it's a pretty chance it'll be a good-sized animal. I bought some 200 NAB blems from SPS and was blown away by how good they shoot over Re-15. I might be hard pressed to go back to the Sierras.
