My all-time favortie is the Winchester Low Wall, but they are very limited for scope sights.
This one I built as a .22lr, a poor photo from a gopher shoot.

I've built several using Dakota actions but have to do radical alterations to the lever and add new bench-made guard and trigger.

The absolute best for a modern hunting rifle is the Hagn. Martin Hagn invented the action after Hartman, of Hartman & Weiss, had a failure with a Heeren on an Alaskan hunt. This is one in process of metal reshaping at my bench.
