I have had more than a half-dozen rifles built on Mauser actions, and I still two and my daughter has one. My .257 AI is on a Mexican Mauser action, as is my daughter's 7mm-08. Both will shoot 1/2-inch three-shot groups with loads that they like. The .257 AI has a Krieger barrel and the 7mm-08 has a Douglas Premium barrel. The third one is a .404 Jeffrey built on an InterArms Mark X action. It easily shoots one-inch three-shot groups from a good bench rest--with open sights. All three of these rifles were built by the same gunsmith who is literally a wizard when it comes to building on Mauser actions.
I have also had several rifles built on both short and long Remington 700 actions, but I no longer own any and have no plans to acquire any more. YMMV.
