I've never seen a reamer for for it, or found any mention of a 358 AI. But you have to admit, it would be something different.

I could go with one of the larger 35 cals, but this is part of my mission to have one barrel for every round based on the 308 case. I figure that an AI is still techincally based on the 308 case, so that counts. Plus I get the cool factor that comes with having something different.

More than likely, I'll end up with a standard 358 though. It's just such an interesting and over looked round. I've always wanted one anyways.
