I thought I would share this as I have never seen this happen before. Was out with my mate and his 308 Steyr zeroing last night, on the last shot he noticed a hell of a kick and the bullet was way off. Looking down with the torch we spotted this and a hairline fracture on the other side as well, you will even notice the scope has slid forward.
Ammo used was factory Sako.
Gutting thing is this rifle was purchased Jan 2013 last year and has had less than 80 shots through it!
