Regarding the revolver pic, what's you're seeing is a severely gapped and mistimed revolver, probably caused by some idiot 'snapping' the cylinder closed like in the old gangster movies. Over time, that bends the crane, which holds the cylinder in place, allowing it to lock up slightly off-center. Erosion of the barrel throat occurs over time as the weapon is fired, and is corrected by shimming the cylinder to close up to the forcing cone (where the bullet enters the barrel from the cylinder). Anything more than .003" will do what that picture demonstrates. True. It is an extreme case as well as an extreme cartridge. But, it would be hard to show the effect using a smaller weapon in better condition. To an extent, every revolver displays the same fault, because the gap between cylinder and barrel is part of the design. The first time the weapon is fired, it will jet gas to the side. Over time, wear, insult and damage will cause the gap to increase, throwing more gas, and the cylinder will drift out of alignment, shaving lead off the bullet and sending fragments sideways along with the gas. This also makes hitting anything more a matter of luck than skill, because the bullet is not launched cleanly. A hammer is a pretty simple tool. And it isn't hard to break. A gun can do many of the same things, but it is more complicated. There is more to go wrong. A semi-automatic doesn't have the cylinder alignment problem, but it has its' own set of things to know and do, and not do. Not necessarily. I've fired older revolvers with a considerable gap which displayed perfectly acceptable accuracy despite the shavings/unburnt powder jetting to the side. It's when the crane is bent from the 'wrist-snap' closing method that causes them to enter off-center. The weapon in the image appears to be a Ruger Redhawk/Super Redhawk, which is sized and chambered for .44 Magnum on up. Those big cartridges throw a lot of flame even in a tight gun, and one with even a minimal mistiming issue will show immense side-blast. Hmmm... Well, of those guns I noticed shaving lead, and this is a very small sample, all of them sucked. I suppose I might have overlooked the problem in a weapon I liked. So, in terms of what can go wrong, there is the gap between barrel and cylinder, there is the alignment of the cylinder axis with the centerline of the barrel, and there is the small matter of actually lining the chamber up behind the barrel every time the action rotates. Three different things. On the other side of the coin, the automatic has its' share of issues. A weak round can fail to cycle, leaving you momentarily disarmed. A dud also requires two hands to deal with, and until you do, no gun. For some folks, the ability to just move along to the next round is worth a lot. Not to mention some are fussy with different bullet shapes, which can limit their performance, there is a built-in instability for a dropping-breech design like the 1911 and others, and feeding is dependent on the weakest part of the weapon, the magazine. Revolvers can jam as well, from extreme dirt and grit to overpowered rounds locking against the recoil plate.
