well,,maybe i should just be quiet about the coon killin,,BUT here we go
just remember if you are going to use STEEL you are going to pick up a choke,,,SO if you are shooting an open barrel you could be at a loose modified choke,,at best and tight improved cylinder at worst
steel is one of those things we are all going to have to use in the future,, and i was never a steel guy until i went to a shooting seminar put on by the state here where i live,,man what an eye opener
the state furnished the shells and instructors,, all i had to bring was lunch and a shot gun,,,the gun i was shooting was an old double i have cut to 24" cylinder bore,,i used it for cowboy action when i was doing that a lot
they were throwing clays for us,,i was shooting steel 8's outa my ol double and grinding those birds to smoke,, the yardage varied from incoming at 20yrds to passing at 30-35,,,to out going at 40+,,,,this was the very first time i had ever used STEEL shot,,,i will tell ya i was really impressed,,all the BS i have heard went right out the door
this smaller shot size may or may not work for coons,,, BUT,, i would definitely get the biggest shot size in steel you can find,, i don't know much about steel shot sizes,,, but BB's should work just fine,,if you can get bigger stuff try a box of that
you should put it on a pattern board to see what your gun will do with it,,,once you see where it patterns and what the pattern looks like,, you will know if it will work or not,,,try it at 35yrds,,,i bet you will be surprised with steel,,i know i was
a .22 on a running coon,,,ya right,,,a body shot won't do it,,, i pick the scatter gun
MY .02 YMMV
