I suspect that nearly all of the same issues would be in play on a 696, that were in play on the 13/19/65/66 getting pounded with 125 .357's? And what I think about the cause of their issues would be the same as well. Slightly off timing, jacketed bullets, a powder charge that needed to be stomped on to get it all into the case, and perhaps a forcing cone that's a bit rough. Get all of them together in one place at one time? Poof, broken gun!
