The .30/40, .303, .30/03, .30/06, .405win, .35win have all been regulars in the 95 Winchester for 100 years plus. Not too mention the .45/90 and /50/110 in the 86 Winchester. These are all longer rounds. The 9.3 is a bit out of character but it should work. Very many 95Winchesters went to Europe for the Russian army, I'll bet there are some 95s over there rebarreled in 9.3x??. Still does seem strange for a lever Winchester.
