I had a Ruger model 77 in 30-06 as my first deer rifle. I had a gunsmith put a Timney trigger on it. That gun wasn't right after that. I could close the bolt and the button wouldn't stay back so it wasn't ****ed. I took the safety off once to shoot at a deer and it fired. I closed the bolt once and it fired. You are asking yourself why I kept using the gun right? Well I had it looked at by the original gunsmith and 3 others with no luck. It kept malfunctioning. I could never trust that gun again so I sold it to a gun store with the original trigger. I told them what it was doing and that several gunsmiths had tried to fix it. I hope to heck they actually got it fixed before they re-sold it.
I now have a Browning BAR in 30-06 and LOVE IT.
