Many hunters will go to the range, fire a few rounds supported to check zero, and pronounce themselves "good" for the season. Many others don't even do that. From looking at some of the groups on targets left downrange (we all do it- be honest), there's a whole lot of hunters that would be pushing it to put a good shot on a deer even at 100 yards supported. There's much more to hunting than just marksmanship, but marksmanship is an essential part of being a successful hunter. I shoot enough that I know if I fail to successfully recover a deer I shot at, it WON'T be due to me not having practiced in the basics- it will be due to some other factor - that is still most likely my fault.
