One MRC 1999 in 375 H&H (stainless), one in 270 Win (CM). Neither has been shot much but good groups so far. 375's raceways are a little rough but will probably smooth up with use.

Given a choice for a new build, I'd probably use a beat out pre-64 Win 70 or a 98 Mauser. Not quite sure why, as I would need to upgrade the 70 or 98 with one piece, inside-the-bolt bottom metal and improved 3-way safety and that takes the price above the MRC. Thinking about it now, I get a lot of confidence from the use of an action that's been around for decades, and for me, on an expensive hunt, that's worth a bundle.
