Greg,
I use bore snakes when hunting with a blackpowder rifle - which is the majority of my big game hunting. I do not do it with a shotgun because I am rarely far from a truck and if actually needed "in the field," it probably would not suffice. The only time I have ever needed anything when hunting with a shotgun is when a fall or slip ends with a muzzle being plugged. At that point, your type of snake is probably useless. Willows, cattails, and Phragmites are usually abundant and sufficient.
But if I was going to carry a snake, I would either use a plastic-coated cable snake, or I would make one from the heaviest gauge weed-trimmer line. The latter is what I use with my rifles. The line is stiff enough to push through many obstructions, though I think it would not be hard to find snow or mud that would be too stiff for it to overcome. At the other end, a brass washer and pierced foam earplug or similar will work as a jag. I skewer a cotton patch with the sharpened tip of the line. The patch can be soaked in water or whatever you like. With bp rifles, I like to keep them clean of fouling asap rather than wait until I get back to camp.
Anyway, maybe something in those comments would be useful, but I think it really revolves around what your motivation is for using one in the field.
