I was looking at a Kriefhoff "Big Five" double the other day and also noted they can be had in both .375 H&H Magnum and .375 Flanged among other calibres.

Now I always thought the Flanged version is loaded generally down in pressure and velocity a little due to it being used in weaker actions ie doubles and singles vs bolt actions for the Magnum version.

So if the Krieghoff can handle the magnum version could not a flanged version also be loaded to the same velocity levels?

(given the fact the flanged version is the only one that really seriously should be considered in a double).

Second question. If you had the choice of either a 9.3x74mmR or a .375 Flanged which would you go for? And why?
