At the time, they were made to help fit a weight class. I was not aware that they were "out of date," but I have not followed bench rest for many years. Just in the last year or two, someone was looking for a scope to go with a rifle from that period, and he thought that a Remington was too expensive or hard to find or both. Probably if you Google "remington benchrest scope," you will get an idea of whether or not that is true.
