Thread: What would have this felt like?

Had old brass do that some years back. Luckily it was a very mild load, Son was shooting and he did not notice until he could not feed the next round.
Was very old brass of my Dad's, some of it had been worked hard and a touch hot.
Did the bent paper clip in some other brass when I got home and dumped the lot. Spured me to go and buy new brass.
Cheap stuff for the lever and Lapua for the bot action.
