It's been a while since I was 14 but I know the two guns that I used around that age. One was a lever action 30-30 that I used mainly in Michigan for shots 100 yards or less. When I was 15 I made my first trip to Wyoming with my father and used a bolt action .270. I had been shooting since I was younger with .22s and .223s. I never had a problem with either and I was a tall drink of skinny water too! Sighting in either of these guns passed about 12 shots did get the shoulder a little soar but once they were sighting in I never had a problem using them for hunting. I think if you have been shooting a while most guns would work for you.
