Its not some kind historic rifle; its a overly heavy Ruger with a real nice handle. Before they became a cult classic of a sort they were a discontinued rifle on the bargain rack for $999. I know, because I put them back on the rack after just about falling through the floor. Its your gun, do whatever you want with it, whether thats rechambering, shooting as is, looking at it or selling it.
Myself; I'd sell it and buy a Winchester, or really, just about anything else.
A little harsh... nobody who has handled the .375 RSM would argue the "overly heavy" assessment... they are pigs, and far too nose-heavy... that said, they are also an incredibly well made rifle... a solid, go anywhere, do anything sort... and usually with exceptional walnut on them. The beauty of good walnut is that it is not difficult to restore to it's former glory... or better. The .458's have better heft and balance, given the larger bore reduces significant weight. I have always thought that they should have made the .375 H&H in the Express contour... that would be just about the perfect all-around rifle.
