Well that stinks. Had my first 44 mag case head separation today. Dan Wesson 744 23.5 gr H110 .431" 240 gr Zero JSP Remington brass that has been fired many times. Unsure of the amount. Recoil was normal. Didn’t even know it happened until I was done shooting and the case head was sticking out at an angle. Any advice for getting the brass removed from the cylinder?? Seems like it’s really in there. Someone told me to get some compressed air and flip upside down so it freezes the brass and cylinder to help contract the brass. Then use a cleaning brush to knock it out. Going to try that before I use any tools and risk scratching the cylinder. Was a fun day though! Shot plenty of rounds.
