I have had the 1717, Cooper 57M Classic and the 452 American.
The 1717 was the most accurate, the Cooper fit the best by far.
Buying one today, I would look hard at the new Tikka.
Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
