I've just checked and it appears hunting as such has been incorporated into the Rifle Shooting and Shotgun Shooting merit badges. The BSA rifle Shooting philosophy and merit badge requirements are:
“ Unless a rifle is handled incorrectly or recklessly, it is not dangerous. A rifle, like any other precision instrument, is manufactured to perform a specific task and can do so at no risk to the user or others. By earning this badge, Scouts can develop their shooting skills while learning safe practices. ”
The Rifle Shooting merit badge was one of the Original 57 Merit Badges issued by the Boy Scouts of America in 1911.
