Would you want to go on a hunting trip with someone who had never fired a gun, or who did not know how to aim? There is a big different between knowing abstractly that you need to pull the trigger and having actually done so, especially with higher-caliber rifles.
You're arguing my point: target practice is to gain skill to kill with the weapon. I wasn't taking a specific moral stance, I actually believe as long as the government is allowed to have weapons the people should be able to as well. I simply have no illusions what guns are for.
