That's some expensive ammo to be using for a training course.
Blaser is good training ammo. Of course some here would say CCI ammo blows up Ruger
Interesting that the instructor thinks it fired out of alignment. If that's the case, the firing pin strikes on the fired shell would not be centered. I suppose it could be some sort of hang fire and it went off while the shooter was pulling the trigger and rotating the cylinder.

I'd say it was not likely so far out of index that it could fire the primer and not put the bulled in the forcing cone. It may well have been out of index some and overstressed the forcing cone causing the barrel to split at the cone and the resultant gas escape destroyed the shroud. Lacking full scientific detail, otherwise a reliable report.
Is there nothing so sacred on this earth that you aren't willing to kill or die for?
Nothing against Ruger (as I'd love an OLD speed six in .357 or a good Blackhawk/Redhawk), but two words in a snubby: Smith, and Wesson.
Ruger has just released that little revolver in a 357 magnum. All though it looks the same it does weigh about 4 ounces more and it's made with stainless steel instead of plastic.
