JSB exacts(if you can locate them), CPL's(Crosman premier lights) Weihrauch FT's(my new favs) and the cheap Gamo hunters shoot a tight group. When I first started the airgunning scene I wanted a heat seeking tracer pellet that would do 1600 fps.
IMO there is no need for a pellet "specialized" in plinging or hunting. As long as you can hit with it, use it. Shot placement is the key when hunting as is when punching paper. As a side note though (my bit of hypocracy for the evening)I do also have a few tins of JSB predators and crow magnums, I can't express the pure joy of watching a tree rat get hit by either of the two.
