Yeahhhh. When i first started reloading i wanted to make sure my primer depth was ok. Primed up a 223 case and put in ar. Place against mattress thinking ok this will muffle it...pull trigger and the gf comes running. Yeah. Forgot about it having a birdcage on it and the blast will just come right out the sides. Nice burn mark on my mattress that looks like a star. Good thing i got rid of her so i dont hafta hear about it anymore.
