Sure looks a like an uncontrolled pressure event or maybe talking when he should have been listening!
An over-pressure situation was exactly what it was. According to Hornady's response to THEIR factory load that blew off my nose. I wasn't 'talking', either. And just who, pray tell, should I lissen to on this thread? You? Fred? 'Squawker?
factory load, likely a manufacturing bobble, any other issues with that lot# ? Maybe a barrel obstruction, cleaning patch, cleaning rod etc?
