Sproule, 30 yards is pretty much too far out for a recurve. Well unless you use sights and the bow is real fast. I can understand that if your bow is really slow that a deer may jump the string at 10 yards. Of course a responsible hunter wouldn't hunt with something that slow would he? I know I wouldn't. I'm guessing your arrow would be going all of 100 ft/sec or so.
Sproule maybe for the deer's sake you should be using a crossbow. Maybe a nurf bow!
