If you read the following article you will see some states require as little as 3 hours fire arms training a year with the rest being 16 hours or under. As the article states the training is mostly target shooting on a range. While any firearm owner who enjoys shooting will probably do at least this much the average hunter is spending days tracking and shooting at a moving target. While we cant train anyone with the target shooting back a moving hard to spot target is far more useful than shooting at a piece of papers even if it has a picture of a bad guy.
