I have a ruger 77 MK II S.S. 270 Cal. Was deer hunting the other day, this rifle has the three postion saftey. When I went to unload it, I grabbed the bolt with the saftey all the way back, in the on position. The bolt lifted up half way up, but it wouldn't came back to eject the shell. So then I thought I need to move the saftey to the middle position, then I push the saftey to the middle postion and It went off !! damm near crapped my pants. I've tried it " yes with the ammo out" again and it will fire every time if you lift the bolt half way up with the saftey on and then move the saftey to the half way position with out touching the tigger. This is the first year I've used this rifle, been setting in the safe, only been fired to sight in the scope. My other 77 MKII you can't left the bolt at all with the saftey all the way on. Has any body else had this problem?
