IMHO 10lb is too heavy for a 9.3x62; I have a full custom 9.3 at a bit over 9lb, recoil is light but it does get heavy to carry by the end of the day.
I've also got an 8.2lb, 9.3 it's not pleasant to shot over the bench, but it's the one I use for serious hunting. I don't notice the recoil in the field and its good to carry, don't know that I would go any lighter.
Barrels I've had good results with the 24 inch Walthers, shoot well and easy to clean, my 9.3s are 0.60 and 0.625 at the muzzel, would not want heavier.
Scopes, one wears Leupold 2.5x8 the other Kahles 2-7. I think the Kahles is the better scope, but the Leupold is afine choice as well.
