Hello, I've never been much of a choke person as I don't do much shotgun hunting anymore. What guns I do have with chokes are marked full, mod, cyl. or something along those lines. So the 1/4 and 1/2 and 3/4 chokes you refer to are probably similar to the chokes I mentioned. Full for ducks,geese, fox, mod for pheasants and rabbits, cyl for skeet. One should never shoot slugs from a full choke barrel/choke. Others may have a better idea regarding the mixing of chokes, however, I don't see the need to mix them up as I am the person who would chose the wrong barrel first. Good luck with your hunting.
