One occasion 15 years ago when my son was 11. On an unusually cold morning, T/C Contender carbine in 30-30, big fat doe broadside about 35 yards away. Click. I reached over and opened/shut the action so it would cock again, deer still standing there. Click. My son opened the action and reloaded a fresh round. Now bambi and her two sisters are becoming concerned and start blowing at us. Bang! Since then we call that stand the clickclickbang stand.

Primer was dented, but it looked a little light. Never happened again, and my son wanted to keep the dented round as a souvenir so unknown if it would fire with a better primer strike. I think a little moisture froze in the space where the firing pin is and prevented a full hit on the primer. Maybe.
