When I arrived at the range today the range officers were all gathered together looking at a revolver. The story was as follows: One of the range officers was shooting his father's S&W 625-3 (45acp) revolver with non-factory loads. Apparently one of the rounds was loaded with an EXCEPTIONALLY hot load and the results are below. Thankfully there were no injuries. There is still a piece of the firearm that nobody could find.
Notice how bowed the top of the frame is. Notice the crack inside of the upper section of the exposed cylinder in the first, third and fourth picture. This nearly ripped a third section of the cylinder apart.
THIS potential is why I always wear eye protection.
