Boy this is getting real interesting...are we looking at gas handling as well as strength or just strength ? I want both in an action . And hopefully we are comparing just Factory Rifles because there are plenty of custom and semi-customs that no one mentioned.

After owning a few mausers and talking to just a few gunsmiths I would not rate it as an extremely strong action, in my opinion it has more negatives then positives so I won't build another one again. In no particular order I would list them as follows:

Remington ...
Ruger
Winchester
Sako
Weatherby
Savage ? don't know enough about them
