First, there is a Win 94 chambered in 410. Shoots standard 410 shotgun shells pretty well from what I am told.
The other is that you are referring to a Winchester Model 97. That was a shotgun, and a great model too. Actually was the Model 1897, most call a model 97. Was chambered in 12 and 16 guage.
Functionally impossible!! The 94 action is big enough for a round the diameter of, say, the .45 Colt as a MAX. This means that for shotgun shells, it can't digest anything bigger than a .410!
