For me, having seen more than one Spanish small ring with set-back, I would stay away from anything of higher intensity than a .35 Remington. That said, a rifle built like you describe in .35 Rem. would be pretty sweet. If anything, the fact that full-stocked .35R bolt actions don't exactly grow on trees would tend to justify the build in my estimation. I would probably keep it stupid simple with just a receiver sight as well. Really trim and light, with balance. My opinion. Imagine hunting that in the woods with snow coming down.
