I was shooting some Buffalo Bore 230 grain hard cast out of my G20 the other day and when I picked up my brass the primers in two of them were no where to be found. It was very cold and the brass did eject into the snow. I'm not sure if this has anything to do with it. Does anyone know what could have caused this? And should I throw them away, or throw the whole 20 away? Thanks. Wanna kill these ads? We can help!
