S&W 1500, Mossberg 1500, and Weatherby Vanguard are the same action. Polishing, quality of wood, wood finish, trigger guard, barrel contour are the different cost factors.
I have owned a new S&W (had to be rebarreled), and a used Mossberg and Weatherby. I shot prairie dogs for 10 years before the S&W barrel was "problematic".
