Re: jewell, timney or shilen trigger?
I have a Timney in my 700. I like it. Adjusting it down to the advertised 1.5lb capability wasn't a problem, although adjusting down to that weight required the sear engagement to be readjusted. I guess that's what happened to the guy above. If you get a Timney, just specify the pull weight and all will be adjusted for you at the factory. I got mine at 3lbs, but decided to go lower. My only gripe with the Timney is that the trigger is wide. I think it's too wide.
A friend of mine that has his rifle built almost just like mine went with a Shillen. I think I like the Shillen better, just because of the trigger it self. It isn't as wide and feels for comfortable.
