11 months ago I had 24 primers go off at once. It sounded like one explosion. I sent a picture of my injured hand to the priming tool manufacturer.
That got their attention. The top guy called 4 times. All these years I send suggestions for product improvement to reloading equipment manufacturers, and I am ignored. But get hurt with their equipment and I am job #1.
It was caused by trying to insert a primer into a military 38 special case with crimped primer pocket. Usually I just see crimps in 308 and 223.
I have since switched priming systems. I have had to make a lot of modifications to get it to work right.
