I've never had a Mk III, but I have a I and a II. Like Jim, I have no clue how this could occur? I've heard complaints about the new loaded chamber indicator in the MkIII causing magazine feed problems. Are you sure the bolt isn't coming back then simply failing to pick up the next round? If what you described is correct, the empty casing would still be in the chamber. If it is ejecting, then the bolt is just being faster than your eye.

Ruger will fix either problem at no cost to you. But until I get a chance to take apart a Mark III and look at the differences, I can't say whether the chamber indicator could be responsible for your problem or not? I would call Ruger and describe the problem before doing anything else. They are bound to have run into it before.
