The trick is to weigh, or know the real weight of every component for the rifle. 98 Mausers often run 45 ozs. or more, so they can be harder to do.
My rifle maker told me he could get the action alone down to 40 ozs., so that helps. Another 3-4 ozs. off of the barrel, etc. The real weight savings was on the stock, 18-19 ozs., ready to bolt up. After that, it's scopes, and scope mounts. E
