Those calibres in the .323 to .366 range seem to be so effective with heavy 250 gr bullets. Rounds such as the .318 (.330) Westley Richards and .333 were once famous. The 9.3 calibres are increasing in popularity. The newer .338's and the good old .35's. Most have moderate speeds and often do use a round-nose projectile.

Elmer Keith would agree with that statement.

I really do think the round-nose is the true hunting bullet (some might argue a flat point) for controlled expansion. The long pointed spitzer is perhaps a fad of the magnum velocity craze.
