Most guys would never admit to shooting a yearling on purpose...you're the first one. There are a lot of yearlings shot every year though. just take a look at the pickup beds at the hotels and restaurants after the first day of hunting. I use the same trick in pheasant hunting with a bunch of guys. I always tell the younger guys who are impressed with the long tail feathers that they should take the bigger birds with them. The younger birds with the short tail feathers are much better on the table.
