Yes.
Years ago, when I was just getting into custom barreled guns, I had a very informative conversation with a national quality (now deceased) rifle builder. He said if he did everything right building a rifle on a Rem 700 action, he might expect .5 MOA. Do everything just as well on Win 70, and he would expect .75 MOA. The design makes the difference, and I think a Mauser would be even worse. The action twists more, the recoil is transmitted more back into the action, the lock time is slower.
I appreciate Mauser actions as much as the next guy--my last several builds have been based on them. But if my goal was a gun that was "schit eating grin" accurate, they would be about the last place I would start.
