Just reading an older thread.
On the load and velocity above, that should not be taken as representative and perhaps the chrono reading was not reliable.
A 338/375 Ruger is in the approximate class/capacity as the 340 Weatherby. The 340 cannot safely send a 250 grain downrange at 3100fps. The 340 is more of a 2850-2900fps round. In fact, the 338 Lapua, with its much increased capacity, should not be expected to send 250 grains at 3100fps. The Lapua is normally rated at 2950-3000 fps with 250 grainers. Bore-riding bullets or long parallel throats could extend these expectations, of course.
Anyway, even though I love 416Rigby-based cartridges, I think that a 338 "Ruger" is probably about ideal for a 338 calibre and could have been the initial Winchester offering 50 years ago if it weren't for the silly belts that gave up all of the capacity in the case body.
