Hiaring,
I think you'll find the 22-250 to be a bit more than you care to shoot on a gopher field. Also, that 1/12 will not accommodate the low drag bullets you're hoping to use. Not that you need low drag bullets on a gopher field, but it won't handle them.
I'd look at getting a new Howa in .223. Get the standard short action. They are twisted 1-9" and should handle most any bullet you want to give a try on the gopher fields this season.
The SWFA 10X's are good scopes but I'd get the mil/mil version and not the MOA.
If you decide against a Howa or Weatherby Vanguard and stick with Savage, I'd at least steer clear of the 22-250 for your purposes. I break mine out on gophers every once in a while, but it gets old pretty quick.
The .223 sized stuff is more better.
