I fired a squib in a long-slide 1911 once. The boolit lodged pretty much in the middle of the barrel, I unscrewed the antenna off my truck and pounded it out with that. Loaded up and rocked on.
In 15 years of reloading I have made two mistakes, that's one, but I also put a double charge of unique in a 30-06 shooting a 165grain RN boolit. It stamped the markings flat on the back of the case and I had to use a rubber hammer to beat the bolt open. Definitely a double charge and not S.E.E. In both instances, I knew there was something not right about that batch of ammo. After the rifle mistake, I dont mess around! If I have any doubts about the quality of the ammo I have made, I pull every blessed one of those boolits and start over. I have only had to do that once. I decided to be more careful and to adopt reloading practices that are more absolute in the way they are conducted. Also the wife knows to hold all phone calls and not to disturb me when I am charging my brass.
