Ray, I think that if you look at the BC difference between the "lightweight" .338's and the heavier(excluding roundnose) bullets,you'll find that the heavier offer much higher BC's. At ranges beyond 400 yards, they offer flatter trajectories,less wind drift,higher velocities, and higher energy. So,they should be a better performer on all game at extended(400+ yards)ranges. A 225 grain TTSX(with a BC of .514),from my wife's rifle at 2950+,gives some pretty good down range performance!!! memtb
