Brian's right. If one is having mishaps with his reloading then there's some serious holes in your procedures and an effort to identify the problem area should be made and corrective action taken to be sure it doesn't happen again.
If you've ever loaded a good batch of ammo, then you should be able to do it every time. What was different when the batch with the mishaps occurred? One should have no distractions, no drinking, no drugs, no television, nothing that could interfere with your thought process. The ABC's of Reloading do not allow for skipping B.
