Has anyone considered building a .465H&H on a standard Mauser 98 action. The cases can be made from .460WBY brass and bullets are available from Woodleigh. It has approximately the same length as a .404 Jeffrey. A drop box mag could hold 3-4 cartridges and even though it is a recent development (2003) it still has the H&H pedigree. 480gr bullets at 2375fps for 6012ft-lbs at lower pressures than a Lott. The only drawback I can think of is getting a barrel in that bore size.
