i think that common sense should prevail.
small game, yes. whitetail, sure. hogs and bigger game, umm, probably not.
kill range will mostly be inside 20 yards, i'd think.
in all instances i wouldn't go below 9gpp (380grs). going higher will be dependent on how comfy you feel with the arrow's trajectory at all distances and how you aim. i would definitely consider going over 400grs, up to 450grs if possible.
what you need bring to the hunt ... consistent accuracy at 20yds or less, under hunting venue conditions, yes. sharp coc broadhead, yes. knowing the proper shot to take, yes. praying for added luck, yes.
