I just tried loading a cartridge with an O-ring, without actually firing it. The extractor cut clean through the O-ring. So this method would be heavy on O-ring consumption in my rifle. Did you remove the extractor for your experiments? Obviously I could do that, but it would mean using a brass rod to push out each fired case. Any suggestions?
