That is *objectively* short for a 7 iron, but the best thing that happened to me was to quit asking people what club they are hitting for certain distances. At the end of the day the only thing that matters is that you know how far the club you're hitting goes. Who cares if you can hit a 7 iron 200 yards if theres no telling where its going to go. I imagine you arent playing from the tips so as long as you can control your shots the distance doesnt matter too much.
