Reloading: Using a Bullet Puller
How to use a bullet puller to take apart bullets when they can not be safely fired. The bullet may have been over pressed (too short) to safely fire or possibly the primer failed to fire (as in this case). I also own a more expensive collet type puller. It is more expensive but much faster. I feel if you reload you should possess a method to immediately pull apart those rounds that you deem "out of sorts" (avoids future confusion).
