Mauser actions, whether repeater or SS, really do not make optimum target rifles. They are too flexible - the siderails are not deep enough. Military actions also have the thumb cut in the left rail to weaken them. In addition, the front guard screw comes up into the bottom of the recoil lug which is not as good as the M70 where it comes into a flat and pulls the receiver down more uniformly. I grant that some FN actions are well made and make elegant rifles, but they are not champion shooters.
