In order to appreciate the .338 bore as a long range number, it has to be set up accordingly with a long barrel and a high magnification scope. The cartridge in the chamber of a long range rifle is unlikely to be a .338 Winchester; if its not a .338-378 or .338 Lapua, then its a .338 Ultramag or .338 Edge. The 9.3 was never intended for long range duty, but as a moderate range big game killer which has the reputation of being the equal of the .375 H&H, even though the paper ballistics wouldn't lead you to that conclusion. If both the 9.3X62 and the .338 Winchester are loaded with 300 gr bullets, the muzzle velocity is pretty close.
