The VX7 I picked meets your stated criteria (6x max magnification, 62' FOV, 3.8" - 4.5" eye relief, and under 42mm objective).

I haven't developed a bunch of 9.3x62 experience, but one of the rifles I sold after commissioning the additional barrel was a Ruger Express in .338 WM...seemed like just as much overlap as the 375 H&H on the high end. Why wouldn't you shoot a 9.3x62 past 250 yards? I realize the SD and BC are going to be lower, but it seems like it would do just about as well as the .338 WM if you were shooting some of the 236 or 250 grain bullets out there (though I understand those aren't the ideal bullet weights for most 9.3 barrels, and I expect to shoot 286 & 300 grain bullets most or all of the time).

I'm not a fan of long-range hunting- I think there are lots more people trying to do it than there are people skilled/qualified to do it. And I didn't have the 9.3x62 assembly built with the primary intention of hunting it beyond 200 yards. But my plan is to take that assembly to the Henry Mountains when (if?) I finally draw a bison tag and that's one place I think longer range shots are going to be needed. It's also a place I'd want more than a .338 WM, and I'm hopeful that 286 grain Barnes X bullets will shoot reasonably well out to 400 yards if that hunt comes to be.

Not trying to cast stones here, just trying to learn more about this round from people more experienced with it than me.
