I have had to hunt for MRP over the years since it replaced N205, but generally I can find some when I look. My big score was at a gun store going out of business sale, and I bought all they had -- and at a good price too.
As JB says, Norma has distribution problems. I have also heard from a Swedish source that some RL22 is MRP that didn't pass their quality checks. I have used RL22 in some hand loads to good effect.
Something to do when it isn't hunting season.
