I sent MB an email asking about the coating on 45-70 bullets, and could they be driven to 2200 fps. In typical MB fashion, Brad responded in less than 24hrs (I figured Monday would be plenty quick). He didn't know about 2200 fps. I figure it's pushing the envelope, but based on what I've read here and elsewhere, I suspect the coating process they are using will top out in that ballpark. Brad did say they didn't have the one I asked about available coated at present, but they will eventually offer the coating on all products. Sounds good to me.
