In shooting CAS matches I would always do like Cozmo and turn the cylinder after loading to make sure rotation was unimpeded. I wish I had a nickel for every fellow shooter who told me "You know the easy way to load that, don'tcha?" and then proceed to educate me on the "load one, skip one" thing. I noticed it seemed like their SASS number was usually 70,000 higher than mine. As Cozmo pointed out, encountering a high primer or other out of spec issue is inevitable, especially if you reload. I'd rather have my gun function than bask in the "knowledge" of some particular loading procedure. And yet, somehow my gun would wind up with the hammer down on an empty chamber despite my not following the newly received advice.
