"Question:
How do the Vienna mounts compare to the claw mounts? My new-to-me 1903 is my only M-S with original scope mounts so I have no claw mounts for a frame of reference."

I have no 'Vienna Snapper' to cross reference but my claw mount is simple, efficient, reliable, and always returns to precise 'zero'.

From what I have read the Vienna mounts are every bit as good, perhaps a bit less durable(?).
