So I was out elk hunting this year over near John Day oregon. We spotted a heard of 40 or 50 elk about a 1 mile away from us. We decided to hop into my buddies truck so we could get closer. We placed all our rifles in the truck and took off. My buddies girlfriend was hunting with us and placed her gun in the back between the seats. She did not unload her gun(by the way she is a very safe and experienced hunter) Anyways we hit a slick spot and this stupid smart a.. toyota cut power to the truck like it is supposed to and we rolled 2 and a half times. When the truck came to a stop we all smelled that awesome smell of gun powder. Her gun had gone off and the safety was on, while the truck was rolling. I CHECKED THE SAETY AND IT WAS ON! The gun is a Ruger M77 270 and is a factory unaltered gun. I told u all this story to ask a question, has any ever heard of a gun firing when the safety is on? PS[ i know i know why did she have a bullet in the chamber? We all ahve rode hunted so dont judge!!!!!!!!!!!!!!
