Arthur Savage also used a rotary magazine in his '95, 1899 and 99 Savage. I don't believe Savage or Schoenauer copied one or the other. Rather that it was a case of parallel development. As shinbone said, the rotary mag is considered obsolete today but, honestly, for the life of me I don't know why. In a sporting, bolt action rifle it's as useful and fully as good as a box magazine...and definitely smoother in operation. Personally, I'm quite fond of the set triggers used on most of the early M/S rifles and those built after WWII until the mid/late 50's.
My first 375 H&H was in an Interarms bolt rifle. They are about as pure a '98 Mauser as can be had without actually saying Mauser. Consequently, yes, they are fine rifles. I no longer have the Interarms 375 H&H but it's been replaced by a bunch of German pre-WWI and between the wars Mausers. Both 98 and 96. Gotta love 'em!!
