I guess nobody else has blown up a rimfire, so I'll tell my tale of woe. Being an enthusiastic but naive teenager, I thought it would be interesting to slightly flatten the nose of a .22 LR. When I started to squeeze it slightly in a vise, to my surprise the bullet receded all the way into the case. Foolishly shot it. Very loud, and the magazine from by beloved Remington 511P bounced off my forearm. No other damage, and what was left of the case extracted OK.

Same rifle I used for my ill fated shooting at a live round inserted an a medium fresh cow pie adventure.
