The Scout was Col Jeff Cooper's concept of a true, all-round rifle.
A search for Coopers Commentaries will reveal much about its origins, including the fact that he chose .308 Win as "the" calibre.
This rifle was to be a "survival" tool in the truest sense, with utility for all NECESSARY disciplines.
Here is a summary:

The fact is that Steyr have bastardised the concept and have introduced calibres other than the .308. People are paying premium money in the expectation of great things and frequently seem to be disappointed.
