While deer hunting with a Remington 700 Mountain Rifle in .280, I had a cartridge case head separation. Obviously, this ended my hunting for the time. Back at camp, I tried removing the remains of the case with a cleaning rod and jag with tight patching, oversized cleaning brushes, etc. from front and back and anything else I could think of, all to no avail. It almost seemed as if the case was brazed in place. The gun is currently in a gun shop awaiting service. Is there any way I could have removed the case myself and continued the hunt? Hopefully, this is a once in a lifetime event. Of course, I'll be checking the die set-up, getting fresh brass, etc. But, I'd appreciate any tips or advice on removing stuck cases. I'm guessing it could be done with Cerro-Safe. But, I'm hoping there's something less drastic?
