One other factor is barrel rifling twist. Are the rifling twists of the 10.75 and .404 the same? This also has bullet choice impact. Perhaps Buckstix knows for his new rifle?
The barrel twist is the "16.5" that is stamped on the barrel. I don't know the twist rate of a 404.
The Mauser, Oberndorf factory used the same 420 mm = 16.5” twist length in their .404, .416 and 10.75x68 barrels. See page 275 of on Speed’s Mauser – OOSR book.
