I hand load #0 buck(cast my own shot). Patterns look lethal
out to 50 yards. Chokes and wad combos are important. I ended
up with Ballistic Products Multi-metal wads, un-slit(added my
own secret slits), and a factory modified choke tube. When I
tried tighter chokes, with typical hunting wads, the patterns
do-nut holed, or clumped. I played with Ballistic Products
Multi-metal wads(no slits, numbers of slits, types of slits),
until I found some interesting results, and then played with
chokes. Unfortunately I haven't gotten any on coyote results,
since my coyote shooting won't start for a few months yet. I
have to save the world from ducks and deer first. 
Although if they continue to howl outside my window at night,
I might have to start early.
The loads look good on paper, and I expect it won't take too
many .31 cal holes to tumble Wiley.
