You can certainly stick a bullet in a barrel, and fire another on top of it, and get away with it. But you will most assuredly want a new barrel after that, because it will bulge the barrel where the first bullet stuck. The first is a Dan Wesson 357 barrel, 4 bullets stuck near the muzzle. Next is a S&W M&P Model 10 38spl barrel, all 6 in there, with the first one almost out of the muzzle. Last, a 1911 45acp barrel with a nice bulge. That will usually stick the slide partially to the rear when the barrel bushing comes up tight against the bulge.
