My Model Four was inherited. 270. It was amazing. Killed a lot of deer with it. Then it started to jam. I had a cheaper scope on it and bought a new one. When i shot it to site it in, it had a major malfunction. I fired. The next round lodged behind the bolt. Luckily I had shot it enough to feel that the recoil was different. I dropped the trigger assembly and removed the round. It was scary though. There was a live round in the chamber and a live round behind the bolt. If I had pulled the trigger, both would have gone off in my face. My wife was there. She hunts and shoots a 7mm Mag. Not scared of guns. She told me I could buy any rifle I want, as long as I don't shoot that one again. I sold it and the guy I sold it to mentioned that once those are bad, it's hard to fix them. I'm ok with that. It's gone. Won't blow up in my face. My Browning X-Bolt is more accurate and a better rifle. I only miss the Model Four because of the deer I killed with it.
