Fortis, I have owned several #1s over the years and currently have a 7x57 1A. For guns such as the 243 or the 22-250 I use to have where I primarily shot varmints with it I always liked a good variable with at least 9x on the top end. For big game rifles such as my 7x57 I haven't found any scope that works out better for me than one of the old USA made Burris fullfield 4x32 fixed powers. The turrets on these sit a bit more forward than on say a Leupold which allows you to pull the scope back a bit in the rings. Plus these are just nice solid old scopes , bright and with a big fov.
