Re: Primer shelf life?
My Father bought a sporterized '03 Springfield back in the 1960's. With the gun came a bunch of 30-06 cases with a '42 Headstamp on them. They were military brass, sized for that guns chamber and they were primed. I have no idea how long they were primed before he got them but it was at least 30+ years since he got them at the time I started to tinker with them. We were leery of using them to say the least but I had to at least fire them off to use the brass. I took 3 primed cartridges randomly out of each box and fired them (no powder or bullet). All went off. I then loaded light charges with 150gr bullets and all went off. I slowly worked up a load that was accurate in that rifle, it was not top of the charts full boogie, but a 2800fps load none the less. Those were done 10-12years ago and he still is firing them off. If stored properly primers will not go bad.
Our forefathers didn't bury their guns. They buried those that tried to take them.
