I use pure neatsfoot oil for my hunting patches. If I do not shoot my rifle during the day's hunt, I trust the load to be safe for as many days as I might need it. The patch, even dripping wet with oil when loaded, is stretched very tightly around the ball, and the bore gets coated with its contents all the way to the powder. There is not enough oil left in the cloth to foul the powder during the course of the (insert number) days hunt. It does not need an over powder wad. That is assuming you are not using 18 grains of 3Fg as your hunting charge. If I have shot my rifle during the day, and loaded it again, which is guaranteed, I discharge the rifle at camp and clean it right away, then re-load it. My rifle stays loaded all the time I'm hunting. That's just the way I do it.
