If you want a dependable mount system, do not waste time and money on a "no-tap" mount, no matter what the maker says. A good solid mount is the basis for any sort of accuracy that you will get from a scope mounted rifle. If the rifle is a collectable, you will need to weigh the aspects of destroying much of it's collector value by tapping the receiver. In today's world, you may be way ahead of you simply buy a Savage Package Rifle and save the old Mauser for the museum. After all the money that you may spend on the 98k, in order to end up with a passable hunting rifle, you may find out that you are still disappointed in the accuracy that the old world, old technology bore can produce. I am in no way down on military surplus conversions. I have owned and shot a fair number of those, even to the point of having a couple re-barreled and re-chambered. Had a really beautiful 98k in 8mm-06 Ackley Improved. The practical ballistics that I could produce from that rifle only slightly edged out a garden variety 30-06 and I had a bundle in the thing.
