JWS - welcome to the Forum. You've got to the right place to answer questions like this one.
40XB in 300win mag. Do you have much rifle shooting experience? if not, I would not really recommend the magnums to begin with. Better to start with a bit more mild recoil.
40XB any particular reason this model piques your interest? It's a nice rifle, but you can do pretty well with a different model Rem700 that would probably shoot just as well and be less expensive.
Give us some more information and we will be able to help you further...
- Shooting experience?
- Intended use for rifle - big game hunting? targets/varmints? tactical? all of these disciplines?
- At what range do you expect to engage your various 'targets'?
