Hard lessons, but good remindersMost of my ammo failures were of my own making.
I've had case head separation on 300 win mag, blown primers for a couple reasons and squib loads along with the primer failures. As Jovy has stated if it feels wrong stop keeping the muzzle pointed in a safe direction waiting to a five count and unload.
I have a 10mm auto casing I found that was completely blown out and split down the side from the mouth to the web of case. I looked for fingers but didn't see any. I would have liked to see the handgun that fired it though.
Good catch! Shows how small oversights in reloading can cause big problems.I had taken a trip down to Nevada to shoot with a buddy. When I got down there, I was getting misfires in my 223 bolt action.
It wasn't until I got home that I figured out the problem- headspace. The sizing die I was using got a build up of lube and other crud, and was pushing the shoulder back too far when sizing. I now clean the die more often and use a Hornady case gauge to confirm case dimensions.
